live-layers.md | # OmniUsdLiveFileFormat Overview
## OmniUsdLiveFileFormat
OmniUsdLiveFileFormat is a SdfFileFormat plugin that represents “live” SdfLayer`s. The `OmniUsdLiveFileFormat implements the required SdfFileFormat API to properly translate “live” data into Sdf data structures. As such, the vast majority of the code actually lives in OmniUsdLiveData.
> The OmniUsdLiveFileFormat plugin is being transitioned to a new multi-threaded implementation. Within the code-base this new multi-threaded implementation is being referred to as “live v2” whereas this original OmniUsdLiveFileFormat is considered “live v1”. “v1” and “v2” do not refer to a new version of the “live” protocol on Nucleus but an iteration on the actual OmniUsdLiveFileFormat plugin.
See also [Live Layer Details](live-layers-details.html)
## OmniUsdLiveRegistry
This stores a list of all currently active OmniUsdLiveData objects. This is used during omniClientLiveProcess to iterate over every object to call SendDeltas. It is also used during a layer reload which happened because a remote client called layer->Clear(). We trigger a layer->Reload() in that case to generate the appropriate notices, but we need OmniUsdLiveFileFormat to re-use the same underlying OmniUsdLiveData.
## OmniUsdLiveData
OmniUsdLiveData is a concrete implementation of SdfAbstractData which is responsible for:
- Storing the actual layer data in-memory (using OmniUsdLiveTree).
- Communication with Nucleus (through [Client Library Live Functions](omni-client-live.html)).
- Building and sending deltas.
- Reading and applying delas.
- Generating notices.
See also [Live Layer Data](live-layers-data.html)
## OmniUsdLiveTree
This class stores the actual layer data, including both nodes and field values.
## OmniUsdValueHelper
This class is responsible for packing and unpacking VtValues.
See also [Value Format](live-layers-wire-format.html#value-format)
## ChildrenHelper
This class is used to help generate a reorder command from a children list, and also for building a children list from a reorder command.

localization.md | # Localization
## Status of Localization
Localization currently lacks tooling to extract the localization tags mentioned
in this document and there is no plan to implement this tooling in the immediate
future. If you would like to integrate localization in a project, the guidance
in this document should be followed and the localization tooling will need to
be written; there is a prototype implementation here but the code parsing implementation needs to be rewritten using clang’s parser
API, so that it can reliably parse code.
## Localization Overview
When writing code that handles text that will be seen by an end-user, the
Carbonite localization system (l10n::IL10n) must be used.
In C++ code, this system must be used through the
`CARB_LOCALIZE()` macro.
For Python code, bindings are provided which do the equivalent of
`CARB_LOCALIZE()`.
## Usage of CARB_LOCALIZE()
It is required that the full string literal be passed into the
`CARB_LOCALIZE()`, rather than storing it in a separate variable.
This is done to allow the strings to be hashed at compile time, as well as to
make it easy to track which strings are used in UI code, so these can easily be
extracted from the code to compile a list of strings to send to a translation
company.
```cpp
void uiCode(const char *arg)
{
otherUiCode(CARB_LOCALIZE(arg)); // very bad
const char *const kUiString = "Operation Failed successfully";
otherUiCode(CARB_LOCALIZE(kUiString)); // bad
otherUiCode(CARB_LOCALIZE("Operation Failed successfully")); // good
}
```
The returned value from
`CARB_LOCALIZE()` should never be cached; if system
settings are changed, the returned string from
`CARB_LOCALIZE()` may change, so
caching values may lead to stale strings showing on the UI.
Do not use line continuators inside of strings. These will look strange when
they show up in the table of translation entries sent to the translator.
Overly long strings should be broken up using string concatenation
(e.g. `const char s[] = "concat" "enation";`).
Avoid using hex escapes in strings when possible, since they can be
troublesome; for example `"\x7f" "delete"` would show up in the translation
file as `"\x7f" "delete"`.
# Usage of CARB_LOCALIZE() in scripts
The script bindings offer a function named `get_localized_string()`, which has behavior that is identical to the `CARB_LOCALIZE()` macro. Because scripts are not compiled, this function will hash the entire string on every call. If repeatedly hashing strings performs too poorly, the hash can be calculated ahead of time using `get_hash_from_key_string()`; then, the localized version of the hash can be looked up with `get_localized_string_from_hash()`.
`get_localized_string_from_hash()` does take an additional string parameter, which will be returned if that localization entry is missing. It is important that this string parameter still be the key string, so that end users will still see readable US English text in the case where the localization system broke.
Avoid the usage of raw strings in python for localization strings. The file sent to the translators will not show that the strings are raw strings, so the translators may be confused.
It is required to use the `carb.l10n` namespace when calling these functions (e.g. `carb.l10n.get_localized_string("string")`), so that tooling can extract localization keystrings.
# Localization Key Strings
The strings passed into `CARB_LOCALIZE()` are referred to as key strings. The key strings are separate from the US English translation to allow the US English string to change without having to modify all occurrences of that key string in the code.
Key strings should be identical to their US English translation, if possible, because this will make the UI code easiest to read. This will also make the UI usable (although likely odd looking), if the localization system was unable to load. Additionally, using shortened versions of the US English translations as key strings could result in unintended collisions, so that should be avoided entirely.
In the case where one US English string has multiple translations in another language depending on the context, the key strings for each translation should have a suffix added that disambiguates it.
# Formatted Localized Strings
UI strings that need formatted information in them should use the C++20 `std::format` style string formatting. This functionality is available in the ‘fmt’ package, which is available through packman. This is the best formatting style in this case because it does not have security issues if incorrect format strings are used.
If multiple formatted arguments are given in a format string, the format string should always use positional arguments. This should make the process of changing the format order more obvious to translators. For example `"you were going {} km/h in a {} km/h zone"` should instead be written as `"you were going {0} km/h in a {1} km/h zone"`.
# Management of Localized Strings
New localized strings in code must be wrapped in a `CARB_LOCALIZE()` macro. The localization tool (localize.sh/localize.bat) will run through the codebase and extract all of the localized strings into the localization data file (localization.csv). It is the responsibility of the developers to ensure that all strings shown on the UI are wrapped with these macros or script bindings.
*the localization tool is a planned feature* |
logging.md | # Omniverse Logging
Fast, feature rich, and easy to extend
## Overview
Omniverse’s logging system is designed around the concept of a “channel”. A channel is a stream of related messages. For example, the audio subsystem may contain channels named `audio.mp3.decode`, `audio.mp3.encode`, and `audio.spatial`. There can be any number of channels within the process and channels can span multiple shared objects (e.g. .dll/.so).
Each message logged is associated with a single channel. Additionally, each message has an associated *level* (i.e. severity). The available levels are as follows:
- **Fatal**: Unrecoverable error. An error has occurred and the program cannot continue.
- **Error**: Error message. An error has occurred but the program can continue.
- **Warn**: Warning message. Something could be wrong but not necessarily an error.
- **Info**: Informational message. Informational messages are usually triggered on state changes and typically not seen every frame.
- **Verbose**: Detailed diagnostics message. A channel may produce many verbose messages per-frame.
The levels above are sorted by severity. *Fatal* messages are considered the most severe message while *Verbose* messages have the least severity.
To give a concrete example of channels and logging levels at work, a Python programmer would log an informational message as follows:
```python
omni.log.info(f"loading {filename}", channel="audio.vorbis.decode")
```
Logging is a helpful debugging tool for not only users but also developers. However, logging every message in the system would not only slow down the application but also provide a mountain of mostly useless data. Because of this, the logging system supports per-channel filtering of messages. Each channel has the following properties to support this filtering:
- **Level Threshold**: Minimum level at which messages should be logged. For example, if a channel’s level is *Warn*, messages with lower severity (e.g. *Info* and *Verbose*) will be ignored (i.e. not logged).
- **Enabled**: If disabled, the channel will ignore all messages sent to it.
By storing these properties per-channel, the user is able to control which channels are able to write messages to the log. For example, the user can enable all messages for the `audio.mp3` channels and only fatal messages for the `audio.spatial` channel as follows:
```bash
example_app.exe --/log/channels/audio.mp3.*=verbose --/log/channels/audio.spatial=fatal
```
In addition to the per-channel settings, the logging system itself has an *enabled* flag and a *level* threshold. By default, channels will respect the global *enabled* flag and global *level* threshold. However, per-channel, the user
is able to
**override** (i.e. ignore) the global settings. In the command-line example above, when we set the level thresholds, we implicitly told each channel to: be enabled, log only messages at the given severity or above, and **override** (i.e. ignore) the global **enabled** flag and **level** threshold.
::: tip
**Tip**
The global log’s default **enabled** flag is true and its default **level** threshold is **Warn**. Channels, by default, are set to **inherit** (i.e. respect) the global log’s flags.
This means, that by default, an Omniverse application will log all channels’ messages that are of **Warn**, **Error**, or **Fatal** severity.
:::
Above, we covered the basic concepts of the logging system. In the following sections we’ll cover:
- How users can configure logging via the command-line and config files.
- How programmers can write log messages, configure settings, add channels, etc.
- How programmers can be notified of logging events such as a new message, new channels, etc.
## Logging for Users
Logging can be configured by the user via the command-line and/or configuration files.
### Command-Line
Log settings are specified on the command-line with the `<code>--/log/</code>` key. For example, to disable the log:
```bash
example_app.exe --/log/enabled=false
```
Multiple log settings can be supplied on the command-line. For example, to enable all messages (i.e. enable **Verbose**) across all channels, but disable all audio channels:
```bash
example_app.exe --/log/enabled=true --/log/level=verbose --/log/channels/audio.*=disable
```
Supported command-line flags can be found in [Settings Reference](#logging-settings-reference).
### Config Files
Omniverse supports two configuration file formats, JSON and TOML. If an application’s name is **example_app.exe**, the application will attempt to read its configuration from **example_app.config.json** or **example_app.config.toml**.
An example JSON config file is as follows:
```json
{
"log": {
"enabled": true,
"channels": {
"test.unit.logtest": "verbose",
"omni.core.*": "error"
}
}
}
```
The equivalent in TOML:
```toml
[log]
enabled = true
[log.channels]
"test.unit.logtest" = "verbose"
"omni.core.*" = "error"
```
While each file type has a different format, their settings follow the same structure. Available log settings can be found in [Settings Reference](#logging-settings-reference).
### Settings Reference
The following settings are supported by the logging system:
- **/log/level**: The global logging level. Can be one of **verbose**, **info**, **warn**, **error**, or **fatal**. Defaults to **warn**. Example: `/log/level=verbose`
- **/log/enabled**: The global log enabled flag level. Can be **true** or **false**. Defaults to **true**.
Example:
```code
/log/enabled
=
true
```
/log/channels
--------------
Sets the level of all channels matching the given wildcard. The wildcard support * and ?. Values for can be one of verbose, info, warn, error, fatal, or disable. The setting supplied will override the global log settings.
More than one filter can be specified. Multiple filters are resolved in order, provided that they are set in the carb::settings::ISettings system in that order (this may be dependent on the type of serializer used).
The log system subscribes to these carb::settings::ISettings keys and changes the log levels immediately when they are changed in the carb::settings::ISettings system.
Example:
```code
/log/channels/audio.*
=
info
```
/log/async
----------
If true, logging a message does not block the thread calling the logging function. This can increase application performance at the cost of log message appearing slightly out-of-order in the log. Defaults to false.
/log/file
---------
Filename to which to log. Defaults to the empty string (does not log to file).
Example:
```code
/log/file
=
log.txt
```
/log/fileFlushLevel
-------------------
Severity at which a message should be immediately flushed to disk. Accepted values are verbose, info, warn, error, or fatal. The default value is verbose.
Can have a performance penalty.
Example:
```code
/log/fileFlushLevel
=
error
```
/log/flushStandardStreamOutput
------------------------------
If true, immediately flush each message to stdout. Enabling has a performance penalty. Default to false.
/log/enableStandardStreamOutput must be enabled.
Example:
```code
/log/fileFlushStandardStreamOutput
=
true
```
/log/enableStandardStreamOutput
-------------------------------
Log each message to stdout. Defaults to true.
Example:
```code
/log/enableStandardStreamOutput
=
false
```
See also:
```code
/log/flushStandardStreamOutput
/log/outputStream
/log/outputStreamLevel
```
/log/enableDebugConsoleOutput
-----------------------------
Log each message to the attached (if any) debugger’s output console. Defaults to true.
Example:
```code
/log/enableDebugConsoleOutput
=
false
```
See also:
```code
/log/debugConsoleLevel
```
/log/enableColorOutput
----------------------
Taste the rainbow, in text form on the console. Messages will be colored based on severity (e.g. error message are red). Defaults to true.
Example:
```code
/log/enableColorOutput
=
false
```
### /log/processGroupId
Sets the process group ID for the logger. If a non-zero identifier is given, inter-process locking will be enabled on both the log file and the stdout/stderr streams. This will prevent simultaneous messages from multiple processes in the logs from becoming interleaved within each other. If a zero identifier is given, inter-process locking will be disabled. Defaults to 0.
Example:
```
/log/processGroupId = 12009
```
### /log/includeChannel
Writes the channel name as a part of the message. Defaults to `true`.
Example:
```
/log/includeChannel = false
```
### /log/includeSource
**Deprecated**: Alias for `/log/includeChannel`.
Example:
```
/log/includeSource = false
```
### /log/includeFilename
Writes the name of the file that logged the message. Defaults to `false`.
Example:
```
/log/includeFilename = true
```
### /log/includeLineNumber
Writes the line number within the file that logged the message. Defaults to `false`.
Example:
```
/log/includeLineNumber = true
```
### /log/includeFunctionName
Writes the name of the function that logged the message. Defaults to `false`.
Example:
```
/log/includeLineNumber = true
```
### /log/includeTimeStamp
Writes the time at which the message was logged. Defaults to `false`.
Example:
```
/log/includeTimeStamp = true
```
Can be enabled in addition to `/log/setElapsedTimeUnits`.
### /log/includeThreadId
Writes the id of the thread that logged the message. Defaults to `false`.
Example:
```
/log/includeThreadId = true
```
### /log/setElapsedTimeUnits
Writes the elapsed time since the first message was logged. The time printed will use the system’s high-resolution clock. Defaults to `none`.
Valid values are as follows:
- "" or "none": The time index printing is disabled (default state).
- "ms", "milli", or "milliseconds": Print the time index in milliseconds.
- "us", "µs", "micro", or "microseconds": Print the time index in microseconds.
- "ns", "nano", or "nanoseconds": Print the time index in nanoseconds.
Example:
```
/log/setElapsedTimeUnits = ms
```
Can be enabled in addition to `/log/includeTimeStamp`.
### /log/includeProcessId
Writes the id of the process that logged the message. Defaults to `false`.
Example:
```
/log/includeProcessId = true
```
### /log/outputStream
Stream to which to log messages. Options are `stdout` and `stderr`. Defaults to `stdout`.
Example:
```
/log/outputStream = stderr
```
### /log/outputStreamLevel
Severity level at which to log to the output stream. Accepted values are
**Severity level at which to log to the standard output stream.** Accepted values are **verbose**, **info**, **warn**, **error**, or **fatal**. The default value is **verbose**.
- `/log/enableStandardStreamOutput` must be enabled.
- Example: `/log/outputStreamLevel = info`
**Severity level at which to log to the debugger’s output console.** Accepted values are **verbose**, **info**, **warn**, **error**, or **fatal**. The default value is **verbose**.
- `/log/enableDebugConsoleOutput` must be enabled.
- Example: `/log/outputStreamLevel = info`
**Severity level at which to log to file.** Accepted values are **verbose**, **info**, **warn**, **error**, or **fatal**. The default value is **verbose**.
- `/log/file` must be set.
- Example: `/log/fileLogLevel = info`
**Enable most options: channel names, line number, function name, time stamp, thread id, and elapsed time.** Default to **false**.
- Example: `/log/detail = true`
**Enable all of the flags enabled by `/log/detail` along with the filename and process id.**
- Example: `/log/fullDetail = true`
**Indicates whether opening the file should append to it.** If false, file is overwritten. Default is **false**.
- Example: `/log/fileAppend = true`
## Basic Logging for Programmers
The Omniverse logging system is designed to filter messages generated by native code at low cost. In fact, the runtime cost of ignoring a message is a single comparison of an `int32_t`. The cheap cost of filtering messages allows developers to litter their codebase with log messages. Additionally, thoughtful use of logging channels allows both users and developers to quickly get to the information they desire.
A message can be logged with one of the following macros:
```c++
#include <omni/log/ILog.h>
void logAtEachLevel()
{
OMNI_LOG_VERBOSE("This is verbose");
OMNI_LOG_INFO("Þetta eru upplýsingar");
OMNI_LOG_WARN("Սա նախազգուշացում է");
OMNI_LOG_ERROR("这是一个错误");
OMNI_LOG_FATAL("This is %s", "fatal");
}
```
By default, log messages are sent to a “default” channel. The name of this default channel can be specified per shared object or per translation unit. See [Default Channel](#carb-logging-default-channel) for further details.
> **Note**
> Older Omniverse code uses logging macros like `CARB_LOG_ERROR(...)`. When linking to newer versions of the logging system, these macros log to the default logging channel.
While logging to the default channel is easy, the developer will quickly want to log to custom channels. To do this, the developer must first create the channel:
```c++
OMNI_LOG_ADD_CHANNEL(kMp3EncodeChannel, "audio.vorbis.encode", "Vorbis audio encoding.")
```
```c
OMNI_LOG_ADD_CHANNEL(kMp3DecodeChannel, "audio.vorbis.decode", "Vorbis audio decoding.")
OMNI_LOG_ADD_CHANNEL(kSpatialChannel, "audio.spatial", "Spatial (3D) audio.")
```
The `OMNI_LOG_ADD_CHANNEL` macro not only defines necessary storage for the channels book-keeping, it also registers the channel with the logging system. Because of this storage allocation and registration, it is important this macro be called only once per-channel (else you’ll get compiler errors).
There’s subtlety to the statement above. `OMNI_LOG_ADD_CHANNEL` should only be called once per-channel, but that’s once per shared object. For example, if you have a DLL named `audio-mp3.dll` and another named `audio-flac.dll`, both of which contain a channel named `audio.settings`, each DLL will contain a call to `OMNI_LOG_ADD_CHANNEL` for the channel.
`OMNI_LOG_ADD_CHANNEL` should be called within a `.cpp` file and at global namespace scope.
To log to a channel, the developer simply passes its identifier as the first argument to the logging macros covered above:
```c
OMNI_LOG_ERROR(kMp3DecodeChannel, "failed to load '%s'", filename);
// ...
OMNI_LOG_VERBOSE(kSpatialChannel, "sound source is %f meters from listener", distance);
```
If the developer wishes to use the channel identifier in a `.cpp` outside of the file in which `OMNI_LOG_ADD_CHANNEL` was called, the following macro can be used to “forward-declare” the channel identifier:
```c
OMNI_LOG_DECLARE_CHANNEL(kMp3EncodeChannel)
```
`OMNI_LOG_DECLARE_CHANNEL` can be called multiple times within a shared object and even multiple times within a translation unit.
In the following sections, we cover additional considerations for plugin authors, application authors, and Python developers.
### Plugin Authors
When creating an Omniverse plugin, it is necessary to call:
```c
OMNI_MODULE_GLOBALS("example.log.plugin", "Example plugin showing how to use logging.")
```
This macro not only sets storage needed by the plugin, it also allocates and registers a default logging channel. The name of this channel is the name of the first argument to the macro.
For Carbonite plugins, the following necessary macro performs similar actions:
```c
const struct carb::PluginImplDesc kPluginImpl = { "carb.windowing-glfw.plugin", "Windowing (glfw).", "NVIDIA", carb::PluginHotReload::eDisabled, "dev" };
CARB_PLUGIN_IMPL_EX(kPluginImpl, carb::windowing::IWindowing, carb::windowing::IGLContext)
CARB_PLUGIN_IMPL_DEPS(carb::input::IInput)
```
In short, by default, plugin authors have access to a default logging channel. The name of default channel will be the same name passed to `carb::PluginImplDesc` (e.g. `carb.windowing-glfw.plugin`).
As described above, additional channels can be added with `OMNI_LOG_ADD_CHANNEL`.
# Application Authors
When creating an Omniverse application, it is necessary to call:
```c++
OMNI_APP_GLOBALS("example.windowing.native.app", "Native (C++) example app using example.windowing.");
```
This macro not only sets storage needed by the application, it also allocates and registers a default logging channel. The name of this channel is the name of the first argument to the macro.
For Carbonite applications, the following necessary macros performs similar actions:
```c++
CARB_GLOBALS("example.dictionary");
```
In short, by default, application authors have access to a default logging channel for use with their executable.
As described above, additional channels can be added with `OMNI_LOG_ADD_CHANNEL`.
Both `CARB_LOG_*` and `OMNI_LOG_*` macros can be called with an application. However, if you wish to log to a non-default channel, one of the `OMNI_LOG_*` macros must be used.
It is recommended that Carbonite applications should transition to using `OMNI_APP_GLOBALS` or `CARB_GLOBALS_EX` rather than `CARB_GLOBALS` since the others allow application authors to set a description for their default channel.
```c++
CARB_GLOBALS_EX("test.cleanshutdown", "Tests that a Carbonite app ends cleanly even without shutdown of the framework.");
```
# Python Programmers
Logging is available to Python modules via the `omni.log` module:
```python
import omni.log
omni.log.verbose("This is verbose")
omni.log.info("Þetta eru upplýsingar")
omni.log.warn("Սա նախազգուշացում է")
omni.log.error("这是一个错误")
status = "bad"
omni.log.fatal(f"This is {status}")
```
By default, the module’s name is used as the channel name. However, the channel can be specified via the `channel=` argument:
```python
omni.log.info(f"loading {filename}", channel="audio.vorbis.decode")
```
The global log can be accessed via `omni.log.get_log()`. For example:
```python
log = omni.log.get_log()
# disable logging except for the "audio.vorbis.decode" channel
log.enabled = False
log.set_channel_enabled("audio.vorbis.decode", True, omni.log.SettingBehavior.OVERRIDE)
log.set_channel_level("audio.vorbis.decode", omni.log.Level.VERBOSE, omni.log.SettingBehavior.OVERRIDE)
```
# add a callback that can see non-ignored message
def on_log(channel, level, module, filename, func, line_no, msg, pid, tid, timestamp):
print(f"received a message on {channel} from {module} at {filename}:{line_no}: {msg}")
consumer = log.add_message_consumer(on_log)
omni.log.error("this message is ignored because the default channel is disabled")
omni.log.fatal("this message is ignored because the channel is disabled", channel="audio.spatial")
omni.log.verbose("this message will be seen", channel="audio.vorbis.decode")
log.remove_message_consumer(consumer)
### Warning
Logging in Python is significantly slower than logging in native code. 🤷
## Advanced Logging for Programmers
### Default Channel
When using `CARB_LOG_*`, `g_carbClientName` is used as the name of the channel to which to log.
When using `OMNI_LOG_*`, if no channel identifier is specified, the message is logged to the “default” channel. By default, the identifier for the default channel is `kDefaultChannel`. However, this can be overridden by defining the `OMNI_LOG_DEFAULT_CHANNEL` preprocessor symbol. One way to do this is via the compiler’s command-line:
```bash
g++ -DOMNI_LOG_DEFAULT_CHANNEL=kAnotherChannel MyPlugin.cpp -o MyPlugin.o
```
Another way is to simply define the macro before including `omni/log/ILog.h`:
```cpp
#define OMNI_LOG_DEFAULT_CHANNEL kAnotherChannel
#include <omni/log/ILog.h>
OMNI_LOG_ADD_CHANNEL(kAnotherChannel, "example.log.another", "Another logging channel.")
void writeToAnotherChannel()
{
// kAnotherChannel (i.e. example.log.another) is the default channel
OMNI_LOG_INFO("writing message to 'example.log.another'");
}
```
The default channel can be redefined multiple times in a translation unit. For example:
```cpp
OMNI_LOG_ERROR("i'm logged to the previous default channel");
#undef OMNI_LOG_DEFAULT_CHANNEL
#define OMNI_LOG_DEFAULT_CHANNEL kAlphaTestChannel
OMNI_LOG_ERROR("i'm logged to the alpha %s", "channel");
#undef OMNI_LOG_DEFAULT_CHANNEL
#define OMNI_LOG_DEFAULT_CHANNEL kBetaTestChannel
OMNI_LOG_ERROR("i'm logged to the beta channel");
```
### Logging in Public Headers
The Omniverse SDK consist of many utility headers which contain nothing but inline code. Logging from within these public headers can be advantageous. Header authors have two broad approaches to log from within public headers.
**Log to the default channel.** This is the simplest approach. Here all messages logged by the header will be logged to the default channel of the module that included the header.
Something to consider is that such an approach may pollute a module’s default channel. For example, given the example.audio.dll module, whose default channel is named example.audio, if a message from carb/extras/Path.h logs to the default channel, that message will be logged to the example.audio channel. If that header is included in another module, say example.filesystem.dll
</em>, the header’s messages would also appear in <em>example.filesystem.dll</em>’s default channel.
Based on what the header is doing, this behavior can be a benefit or an annoyance. If a header is found to be an annoyance, the default channel can be changed before including the header and restored after the include. See Default Channel for more details.
**Log to header specific channels.** Here public header authors create channels specific to their functionality. An example of such a header:

// Forward declare the channel identifiers so they can be used in this header.
OMNI_LOG_DECLARE_CHANNEL(kExampleUsefulChannel);
OMNI_LOG_DECLARE_CHANNEL(kExampleUselessChannel);
namespace example {
inline void myUsefulFunction() {
OMNI_LOG_INFO(kExampleUsefulChannel, "i'm helping"); // logs to "example.useful"
}
inline void myUselessFunction() {
OMNI_LOG_INFO(kExampleUselessChannel, "i'm not helping"); // logs to "example.useless"

} // namespace example
// This macro allows consumers of the header to allocate storage for this header's channels. It also adds the channels
// to the channel list of the module that included this header. This macro should be called once per module that
// includes this header.
#define EXAMPLE_ADD_CHANNELS() \
OMNI_LOG_ADD_CHANNEL(kExampleUsefulChannel, "example.useful", "Output from myUsefulFunction"); \
OMNI_LOG_ADD_CHANNEL(kExampleUselessChannel, "example.useless", "Output from myUselessFunction")
```
Above we see this approach requires three steps:
1. Forward declare your channels with `OMNI_LOG_DECLARE_CHANNEL`.
2. Specific the new channels when logging.
3. Provide a utility macro consumers of your header can call to add your header’s channels.
The macro defined by the last step should be called once, and only once, in each module that consumes the header. Failure to call the macro will result in link errors. As such, it’s recommended the variable names used to identify the channels are descriptive in order to help guide the user to the missing macro call.
## Message Consumers
The logging system allows for clients to register an interface that will be notified each time a message is to be written to the log (i.e. a message that has not been filtered out).
In C++:
```c++
auto log = omniGetLogWithoutAcquire();
bool sawFatalMessage = false;
auto consumer = log->addMessageConsumer(
[&sawFatalMessage](const char* channel, omni::log::Level level, const char* moduleName, const char* fileName,
const char* functionName, uint32_t lineNumber, const char* msg, uint32_t pid, uint32_t tid,
uint64_t timestamp) noexcept {
if (omni::log::Level::eFatal == level) {
sawFatalMessage = true;
}
});
```
```cpp
}
});
OMNI_LOG_FATAL("this is a fatal message");
log->removeMessageConsumer(consumer);
REQUIRE(sawFatalMessage);
```
Note, in the C++ ABI, the actual notification mechanism happens via the
`omni::log::ILogMessageConsumer` interface. The lambda wrappers in the example above are wrappers around that interface.
The `omni::log::ILogMessageConsumer` can be used to create custom logging “back-ends”. In fact, the Carbonite framework creates such a custom backend to handle parsing log settings and logging appropriately formatted messages to file/stdout/stderr/debug console/etc. Thinking “big picture”, the logging system is a router: it takes messages from multiple input channels and multiplexes them to multiple message consumers:
```mermaid
graph LR
log{ILog} --> std[StandardLogger]
log --> l0[ILogMessageConsumer]
log --> l1[ILogMessageConsumer]
c0(audio.mp3.encode) --> log
c1(audio.mp3.decode) --> log
c2(audio.spatial) --> log
c3(omni.core) --> log
classDef bold font-weight:bold,stroke-width:4px;
class log bold
```
Tests can use `omni::log::ILogMessageConsumer` to ensure messages are logged at appropriate times. As an example, consider the `MessageConsumer` class in `source/tests/test.unit/omni.log/TestILog.cpp`.
GUIs can create an `omni::log::ILogMessageConsumer` to capture log messages and draw them to a graphical element.
### Channel Update Consumers
Developers are able to register callbacks to be informed about state changes in the logging system. The following state changes are supported:
- Channel added to the log
- Channel removed from the log
- Log’s `enabled` flag updated
- Log’s `level` updated
- A channel’s `enabled` flag was updated
- A channel’s `level` was updated
- A channel’s description was updated
The callback mechanism takes the form of the `omni::log::ILogChannelUpdateConsumer` interface. See `showMessageConsumer()` in `source/tests/test.unit/omni.log/TestILogDocs.cpp` for example usage.
### Controlling the Default Log Instance
Omniverse applications are initialized with the `OMNI_CORE_INIT` macro. This macro calls `omniCreateLog()` to instantiate the log returned by `omniGetLogWithoutAcquire()`. If the application wishes for a custom implementation of `omni::log::ILog` to be used, the user can simply pass the custom instance to the `OMNI_CORE_INIT` macro. |

Manipulator.md | # Manipulator
Manipulator provides a model-based template that is flexible for implementing navigation and editing objects, points, and properties. It’s a container that can be reimplemented. It can have a model.
## Immediate mode
It’s possible to regenerate the content of the Manipulator item by calling the `invalidate` method. Once it’s called, Manipulator will flush the old children and execute `build_fn` to create new ones. Suppose the `invalidate` method is called inside `build_fn`. In that case, Manipulator will call `build_fn` every frame, which provides, on the one hand, a maximum of control and flexibility to the scene configuration. Still, on the other hand, it also generates a continuous workload on the CPU.
```python
class RotatingCube(sc.Manipulator):
def __init__(self, **kwargs):
super().__init__(**kwargs)
self._angle = 0
def on_build(self):
transform = sc.Matrix44.get_rotation_matrix(
0, self._angle, 0, True)
with sc.Transform(transform=transform):
sc.Line([-1, -1, -1], [1, -1, -1])
sc.Line([-1, 1, -1], [1, 1, -1])
sc.Line([-1, -1, 1], [1, -1, 1])
sc.Line([-1, 1, 1], [1, 1, 1])
sc.Line([-1, -1, -1], [-1, 1, -1])
```
```python
sc.Line([1, -1, -1], [1, 1, -1])
sc.Line([-1, -1, 1], [-1, 1, 1])
sc.Line([1, -1, 1], [1, 1, 1])
sc.Line([-1, -1, -1], [-1, -1, 1])
sc.Line([-1, 1, -1], [-1, 1, 1])
sc.Line([1, -1, -1], [1, -1, 1])
sc.Line([1, 1, -1], [1, 1, 1])
# Increase the angle
self._angle += 1
# Redraw all
self.invalidate()
# Projection matrix
proj = [1.7, 0, 0, 0, 0, 3, 0, 0, 0, 0, -1, -1, 0, 0, -2, 0]
# Move camera
rotation = sc.Matrix44.get_rotation_matrix(30, 50, 0, True)
transl = sc.Matrix44.get_translation_matrix(0, 0, -6)
view = transl * rotation
scene_view = sc.SceneView(
sc.CameraModel(proj, view),
aspect_ratio_policy=sc.AspectRatioPolicy.PRESERVE_ASPECT_FIT,
height=200
)
with scene_view.scene:
RotatingCube()
```
## Model
The model is the central component of Manipulator. It is the dynamic data structure, independent of the user interface. It can contain nested data, but it’s supposed to be the bridge between the user data and the Manipulator object. It follows the closely model-view pattern.
When the model is changed, it calls `on_model_updated` of Manipulator. Thus, Manipulator can modify the children or rebuild everything completely depending on the change.
It’s abstract, and it is not supposed to be instantiated directly. Instead, the user should subclass it to create the new model.
```python
class MovingRectangle(sc.Manipulator):
"""Manipulator that redraws when the model is changed"""
def __init__(self, **kwargs):
super().__init__(**kwargs)
self._gesture = sc.DragGesture(on_changed_fn=self._move)
def on_build(self):
position = self.model.get_as_floats(self.model.get_item("position"))
transform = sc.Matrix44.get_translation_matrix(*position)
```
```python
with sc.Transform(transform=transform):
sc.Rectangle(color=cl.blue, gesture=self._gesture)
def on_model_updated(self, item):
self.invalidate()
def _move(self, shape: sc.AbstractShape):
position = shape.gesture_payload.ray_closest_point
item = self.model.get_item("position")
self.model.set_floats(item, position)
class Model(sc.AbstractManipulatorModel):
"""User part. Simple value holder."""
class PositionItem(sc.AbstractManipulatorItem):
def __init__(self):
super().__init__()
self.value = [0, 0, 0]
def __init__(self):
super().__init__()
self.position = Model.PositionItem()
def get_item(self, identifier):
return self.position
def get_as_floats(self, item):
return item.value
def set_floats(self, item, value):
item.value = value
self._item_changed(item)
# Projection matrix
proj = [1.7, 0, 0, 0, 0, 3, 0, 0, 0, 0, -1, -1, 0, 0, -2, 0]
# Move/rotate camera
rotation = sc.Matrix44.get_rotation_matrix(30, 30, 0, True)
transl = sc.Matrix44.get_translation_matrix(0, 0, -6)
scene_view = sc.SceneView(
sc.CameraModel(proj, transl * rotation),
aspect_ratio_policy=sc.AspectRatioPolicy.PRESERVE_ASPECT_FIT,
height=200
)

materials.md | # Omniverse Materials
Materials in Omniverse are supported using [MDL](#term-MDL).
The NVIDIA Material Definition Language (MDL) is a shading language specifically designed for defining and describing the appearance of materials in computer graphics. It allows artists and developers to create highly realistic materials by specifying their physical properties, surface characteristics, and how they interact with light.
## Key Features
- **Physically Based:** MDL is based on the principles of physically based rendering, which aims to simulate the behavior of light in a physically accurate manner. This enables the creation of materials that closely resemble real-world substances.
- **Modularity:** MDL supports a modular approach to material creation, allowing users to define reusable building blocks called material components. These components can be combined and layered to create complex materials with different properties.
- **Procedural Texture Generation:** MDL includes a rich set of procedural texture functions that can be used to generate textures based on mathematical algorithms. This enables the creation of textures with intricate patterns and variations.
- **Scalability:** MDL materials are designed to be scalable, meaning they can adapt to different levels of detail and performance requirements. This allows materials to be used in a variety of contexts, from real-time rendering in games to high-quality rendering in film and visual effects.
- **Interoperability:** MDL is designed to be compatible with various rendering engines and applications. It provides a standard format for material exchange, allowing materials to be shared and used across different software and hardware platforms.
For more information on MDL.
## Asset Validation for Materials
Asset Validation in Omniverse refers to the process of verifying the integrity and correctness of assets within the USD ecosystem. Asset validation ensures that the USD files adhere to the required standards, have valid data structures, and are compatible with the supported features and functionalities.
> **Attention**
> The USD ecosystem is becoming more strict in enforcing standards. In some cases this can break older assets authored previous to these changes. We have introduced an Asset Validator Extension to help fix these issues and create more robust assets. If you suspect something is wrong when you load an asset or you see a warning, please run the extension which can be found under the :menuselection:
> Windows > Utilities > Asset Validator
> sub menu. Refer to the [Asset Validator Documentation](https://docs.omniverse.nvidia.com/extensions/latest/ext_asset-validator.html) for more info.
## Material rules
| Rule | Result |
| --- | --- |
| Missing Material Binding API | Ensures the MaterialBindingAPI is applied to on prims with bound materials |
### Dangling Material Bindings
Ensures that the bound material exists in the scene
### Material path verification
MDL assets require absolute paths or relative paths prefixed with `./` to resolve properly. This Rule suggests to prefix ambiguous MDL asset path(s) with a `./` to enforce that it is a relative path (i.e `./M_PlantSet_A13.mdl`).
### Texture Checker
A RuleChecker which handles locating texture files automatically.
### Normal Map Texture Checker
UsdUVTexture nodes that feed the inputs:normals of a UsdPreviewSurface must ensure that the data is encoded and scaled properly
The full set of Asset Validation Rules
### Overview
### Material Templates
Omniverse comes with several template materials, including a physically based glass; several general purpose multi-lobed materials useful for dielectric and non-dielectric materials, skin, hair, liquids and other materials requiring subsurface scattering or transmissive effects; and USD’s UsdPreviewSurface.

<h4>
Overview
</h4>
<p>
The UsdPreviewSurface shading model aims to provide a simple and intuitive set of parameters for defining a surface appearance. It is part of the larger USD ecosystem and provides a standard way to describe surface appearances in USD files. It facilitates interoperability and asset exchange between different software tools and rendering engines, making it easier to share and collaborate on 3D scenes and assets, and as such does not require MDL.
</p>
<p>
The USD Preview Surface shading model supports various features listed below. These parameters can be defined and adjusted within a USD file, allowing for consistent material representation across different applications and renderers that support USD.

## OmniSurfaceBase and OmniSurfaceLiteBase
### Overview
**OmniSurfaceBase** and **OmniSurfaceLiteBase** are physically-based materials designed based on Autodesk® Standard Surface[^2], capable of modeling a wide variety of surface appearances, including plastic, concrete, water, car paint, skin, foliage, foam, wax, wood, velvet, etc.
**OmniSurfaceBase** and **OmniSurfaceLiteBase** come with a small set of parameters with intuitive meanings, ranges, and predictable results.
**Note**
For creating simple materials, the use of **OmniSurfaceLiteBase** is encouraged. In general, **OmniSurfaceLiteBase** renders faster.
**Note**
**OmniSurfaceBase** is not fully supported in RTX - Real-Time mode yet.
**OmniSurfaceBase** consists of the following sections:
- [Base (Diffuse reflection, Metal)](#omnisurfacebase-base-diffuse-reflection-metal)
- [Specular (Specular reflection)](#omnisurfacebase-specular-specular-reflection)
- [Transmission (Specular transmission)](#omnisurfacebase-transmission-specular-transmission)
- [Subsurface (Subsurface scattering, Diffuse transmission)](#omnisurfacebase-subsurface-subsurface-scattering-diffuse-transmission)
- [Coat (Specular reflection thin-shell)](#omnisurfacebase-coat-specular-reflection-thin-shell)
- [Sheen (Specular retro-reflection)](#omnisurfacebase-sheen-specular-retro-reflection)
- [Thin film](#omnisurfacebase-thin-film)
- [Emission](#omnisurfacebase-emission)
- [Geometry (Opacity, Geometry normal, Displacement)](#omnisurfacebase-geometry-opacity-geometry-normal-displacement)
**OmniSurfaceLiteBase** is a subset of **OmniSurfaceBase** and consists of the following sections:
- [Base (Diffuse reflection, Metal)](#omnisurfacebase-base-diffuse-reflection-metal)
- [Specular (Specular reflection)](#omnisurfacebase-specular-specular-reflection)
- [Coat (Specular reflection thin-shell)](#omnisurfacebase-coat-specular-reflection-thin-shell)
- [Emission](#omnisurfacebase-emission)
- **Geometry (Opacity, Geometry normal, Displacement)**
## Parameters
### Base (Diffuse reflection, Metal)
| Display Name | Name | Type | Default |
|--------------|---------------------|--------|---------|
| Weight | diffuse_reflection_weight | float | 0.8 |
| Color | diffuse_reflection_color | color | 1.0, 1.0, 1.0 |
| Diffuse Roughness | diffuse_reflection_roughness | float | 0.0 |
| Metalness | metalness | float | 0.0 |
This layer models the base layer, a statistical mix between diffuse reflection and diffuse transmission components.
**Weight**
This parameter sets the weight of diffused reflection or metallic reflectance.
**Color**
This parameter sets diffuse reflection color of the dielectric surface or reflectance value of metallic surface by the probability that light is reflected or transmitted for each wavelength.
**Diffuse Roughness**
Oren-Nayar surface roughness coefficient, simulating view-dependent diffuse reflection. At 0.0, the surface behaves similarly to a fully Lambertian reflection. Higher values are suitable for powdery surfaces like dust, sand, dried clay, concrete, etc.
### Diffuse Roughness
- **Diffuse Roughness: 0.0**
- **Diffuse Roughness: 0.5**
- **Diffuse Roughness: 1.0**
### Metalness
- **Metalness: 0.0**
- **Metalness: 0.5**
- **Metalness: 1.0**
- **Metalness: Texture**
The metallic reflection is modeled as a GGX microfacet conductor BRDF. The absorption coefficient and complex index of refraction are computed from the base color and the specular reflection color. The base color controls the metallic surface appearance, and specular reflection weight and specular reflection color parameters only affect the edge tint.
See [Thin Film](#omnisurfacebase-thin-film) section for more information.
### Metals
- **Nickel**
- Metalness: 1.0
- Base Color: 0.649, 0.610, 0.541
- Specular Color: 0.797, 0.801, 0.789
- **Gold**
- Metalness: 1.0
- Base Color: 0.944, 0.776, 0.373
- Specular Color: 0.998, 0.981, 0.751
- **Copper**
- Metalness: 1.0
- Base Color: 0.926, 0.721, 0.504
- Specular Color: 0.996, 0.957, 0.823
### Specular (Specular reflection)
| Display Name | Name | Type | Default |
|--------------|---------------------|--------|---------|
| Weight | specular_reflection_weight | float | 1.0 |
| Color | specular_reflection_color | color | 1.0, 1.0, 1.0 |
| Roughness | specular_reflection_roughness | float | 0.2 |
| IOR Preset | specular_reflection_ior_preset | enum | ior_custom |
| IOR | specular_reflection_ior | float | 1.5 |
| Anisotropy | specular_reflection_anisotropy | float | 0.0 |
| Rotation (rad) | specular_reflection_anisotropy_rotation | float | 0.0 |
This layer models a GGX microfacet dielectric BRDF under the coating layer. Due to Fresnel, this layer is not energy conversing. Thus the energy that is not reflected is transmitted to the underlying layers.
**Weight**
This parameter sets the amount of the specular reflection. Lowering this value increases light transmission through the object’s volume.
| Specular Reflection Weight: 0.0 | Specular Reflection Weight: 0.5 |
|-----------------------------------|-----------------------------------|
| Specular Reflection Weight: 1.0 | Specular Reflection Weight: Texture |
| The effect of skin oil residue on the surface | |
When metalness is greater than 0.0, this parameter sets the edge tint weight for the metal surface.
| Specular Reflection Weight: 0.0 | Specular Reflection Weight: 0.5 | Specular Reflection Weight: 1.0 |
|----------------------------------|----------------------------------|----------------------------------|
| Metalness: 1.0<br>Specular Color: 0.1, 1.0, 0.72 | Metalness: 1.0<br>Specular Color: 0.1, 1.0, 0.72 | Metalness: 1.0<br>Specular Color: 0.1, 1.0, 0.72 |
**Color**
This parameter sets the color of the specular reflection. While some metallic (conductor) surfaces have colored specular reflections, dielectric surfaces have only achromatic specular reflections.
| Specular Reflection Color: 1.0, 1.0, 1.0 | Specular Reflection Color: 0.0, 0.7, 1.0 |
|------------------------------------------|------------------------------------------|
| Specular Reflection Weight: 1.0 | Specular Reflection Weight: 1.0 |
**Tip**
Setting the specular reflection color for dielectric surfaces other than white is not physically correct.
When metalness is greater than 0.0, this parameter sets the edge tint color.
| Specular Reflection Color: 1.0, 1.0, 1.0 | Specular Reflection Color: 0.0, 0.7, 1.0 |
|--------------------------------------------|--------------------------------------------|
| Specular Reflection Weight: 1.0<br>Metalness: 1.0 | Specular Reflection Weight: 1.0<br>Metalness: 1.0 |
**Roughness**
This parameter sets the surface microfacet’s irregularities that cause light diffusion. At 0.0 simulates a perfect and smooth reflective surface, while increasing the value causes reflective highlights to diverge or appear blurred.
| Specular Reflection Roughness: 0.0 | Specular Reflection Roughness: 0.25 |
|-------------------------------------|-------------------------------------|
| Specular Reflection Weight: 1.0 | Specular Reflection Weight: 1.0 |

Specular Reflection Weight: 1.0
Specular Reflection Roughness: 0.5
Specular Reflection Weight: 1.0
Specular Reflection Roughness: 1.0
Specular Reflection Weight: 1.0
Roughness affects both specular reflection and specular transmission.
Specular Reflection Roughness: 0.0

Tip
====
Roughness can create effects like torn surfaces, galvanized metal, or surfaces with fingerprints and smudges.
Smudges on Clay

Galvanized Metal
================
IOR Preset
==========
This parameter presents a list of known IORs (index of refractions) for various materials, including glass, ice, diamond, skin. One can use custom IOR by setting this parameter to ior_custom and a value for the specular reflection’s IOR parameter.
IOR
===
This parameter sets IOR (index of refraction), which affects surface Fresnel reflectivity. The IOR defines the ratio between reflection on the surface front, facing the viewer, and the surface edges, facing away the viewer.
At values above 1.0, the reflection appears stronger on the surface edges and weaker on the surface front. At values less than 1.0, the Fresnel is disabled, and the specular reflection appears as a uniform highlight over the surface.
Tip
===
At high values, the surface will look similar to a metallic surface. If a metallic look is desired, the metalness parameter is encouraged instead since the range [0, 1] can be easily mapped with an input texture.

**Anisotropy**
This parameter sets the specular reflection anisotropy. Reflectance changes based on the surface orientation are called anisotropic. If the reflectance is uniform in all directions and does not change based on the surface’s rotation or orientation, it is isotropic.
At values above 0.0, the surface transmits and reflects incoming light with a directional bias. Thus it appears rougher in a specific direction.

## Rotation (radians)
This parameter sets the orientation of the anisotropic effect in radians. At 1.0, the anisotropic effect is rotated by 180 degrees. For brushed metallic surfaces, the anisotropic effect should stretch out in a direction perpendicular to the brushing direction.

This layer models a GGX microfacet BTDF within a homogeneous medium interior to the object, under the specular reflection layer. It shares a few key parameters with the Specular reflection layer, including Roughness, IOR, Anisotropy, and Anisotropy Rotation.
If thin-walled enabled, the surface appears double-sided, represented as an infinitely thin shell. Upon specular transmission, the incoming light is not refracted to the opposite side. The refraction index sets to the surrounding medium.
If thin-walled disabled, the surface is considered to be a boundary of a finite-sized solid object. And according to the specular reflection layer, the incoming light refracts when entering and leaving the object.
### Note
**Specular Transmission vs. Geometry Opacity**
Specular transmission controls the surface transparency, while geometry opacity controls the surface visibility. One can use the specular transmission to create a glass surface and then use the opacity to cut the surface.
### Note
In the RTX – Interactive (Path Tracing) mode, if refraction appears black, one may need to increase **Max Bounces Specular/Transmission** and **Max Bounces** in the render settings panel.
Please see RTX Interactive (Path Tracing) mode render settings for more information.
### Enable Specular Transmission
Enables specular transmission layer
### Weight
This parameter sets the amount of light to pass and scatter through the surface. At 0.0, the surface is completely opaque, while at 1.0, the surface is fully transparent.

This layer models the effect of light absorption and scattering within a homogeneous medium interior to the object, where the exiting rays leave at a different surface location than the incident rays.
Subsurface can be used to create materials like plastic, marble, skin, wax, milk, and leaf.
In the path-tracer mode, the subsurface component is calculated using the “Random Walk” technique. The Random Walk uses a stochastic or random process to trace the effect of light scattering through an object, with no assumption about geometric features of the object, i.e., local surface flatness, concavities.
In the real-time mode, the subsurface component is calculated by combining the diffusion profile and path tracing techniques. The diffusion profile is based on the Monte Carlo simulation result that describes the distribution of energy coming out of a semi-infinite flat surface of the scattering medium.
If thin-walled enabled, the subsurface represented as the diffuse transmission of light through an infinitely thin shell.

## Enable Subsurface
Enables diffuse transmission and subsurface layer.
## Weight
This parameter sets the amount of diffuse transmission and subsurface scattering. At 0.0, the surface is represented as diffuse only surface, and a higher value increases the visibility of diffuse transmission and subsurface scattering.
### Table: Subsurface Weight
| Subsurface Weight: 0.0 | Subsurface Weight: 0.5 | Subsurface Weight: 1.0 |
|-------------------------|-------------------------|-------------------------|
## Scattering Presets
This parameter presents a list of known subsurface scattering colors and radiuses for various materials, including apple, milk, ketchup, skin. One can use custom values by setting this parameter to scattering_colors_custom and set a value for color and radius parameters.
## Color
This parameter sets the color of the subsurface scattering effects. When incoming rays reach the surface, they will get tinted by the subsurface color. The subsurface color and radius parameters determine the absorption and scattering within the medium interior to the object.
### Table: Subsurface Color
| Whole Milk | Skin |
|------------|------|
| Subsurface Color: 0.950, 0.930, 0.850 | Subsurface Color: 0.999, 0.615, 0.521 |
<p id="omnisurfacebase-subsurface-scattering-color"><strong>Radius (mfp)</strong></p>
<p>This parameter sets the scattering radius, which describes as the mean free path (mfp). The mean free path is the average distance that rays travel before scattering below the surface and within the volume.</p>
<p>As the rays travel through the volume, they bounce around and emerge from the surface at different locations. This value corresponds to the average length the ray travels between each bounce. The higher the path length is, the further the ray is allowed to scatter within the volume.</p>
<p>At 0.0, there will be no scattering effect. Lower values mean scattered light is absorbed quicker, resulting in a more opaque look. At higher values, the surface appears more translucent.</p>
<p>The scattering radius can be different per spectra.</p>
<p>For example, skin material would have a higher red value in the radius since red light (620-670nm) penetrates and scatter deepest into the skin compared to green and blue lights.</p>
The effect of radius depends on the absolute size of the objects, and hence radius is a scene scale-dependent parameter.
**Scale**
This parameter scales the effect of scattering radius or the mean free path distance. If the scene is not modeled to scale, the scale parameter can be used to adjust the scattering effect. Lowering this value makes the object more diffuse, while at a higher value, it becomes more translucent.
The *Scale* parameter is adjusted based on the scene unit; if the scene scale is in meter, the scale of 1.0 corresponds to 1.0 meter.
**Anisotropy**
This parameter sets the scattering directionality or anisotropy of the “Henyey-Greenstein” phase function of the interior medium to the object. At 0.0, scattering sets to isotropic, and light is scattered uniformly in all directions. Values above 0.0 biases the scattering effect forward in the direction of the light, while values below 0.0 biases the scattering effect backward in the opposite direction of the light.
> **Tip**
> Unlike hard materials, i.e., jade and marble, water-based materials, i.e., orange juice, ketchup, and skin, exhibit strong forward scattering.

This layer models GGX microfacet dielectric BRDF top coating. Due to Fresnel, this layer is not energy conserving. Thus the energy that is not reflected is transmitted to the underlying layers.
The coating simulates an infinitely thin shell dielectric layer, i.e., glass, enamel, lacquer, over the surface. It can create materials like metallic car paint, carbon fiber, oily skin, and wet asphalt.
**Weight**
This parameter sets the amount of surface coating. Lowering this value increases light transmission through the object’s volume.
> **Tip**
> For a realistic result, this parameter should be set to less than 1.0.

## IOR Preset
This parameter presents a list of known IORs (index of refractions) for various materials, including glass, ice, diamond, skin. One can use custom IOR by setting this parameter to ior_custom and a value for the specular reflection’s IOR parameter.
## IOR
This parameter sets IOR (index of refraction), which affects surface Fresnel reflectivity. The IOR defines the ratio between reflection on the surface front, facing the viewer, and the surface edges, facing away the viewer.
At values above 1.0, the reflection appears stronger on the surface edges and weaker on the surface front. At values less than 1.0, the Fresnel is disabled, and the coating appears as a uniform highlight over the surface.
## Anisotropy
This parameter sets the specular reflection anisotropy. Reflectance changes based on the surface orientation are called anisotropic. If the reflectance is uniform in all directions and does not change based on the surface’s rotation or orientation, it is isotropic.
At values above 0.0, the surface transmits and reflects incoming light with a directional bias. Thus it appears rougher in a specific direction.
## Rotation (radian)
This parameter sets the orientation of the anisotropic effect in radians. At 1.0, the anisotropic effect is rotated by 180 degrees. For brushed surfaces, the anisotropic effect should stretch out in a direction perpendicular to the brushing direction.
## Affect Color
This parameter controls the saturation of diffuse reflection and subsurface under the coating layer.
In the real world, refracted rays exhibit internal reflection within the coating medium, which can go back down to the underlying surface to reflect again, thus making the surface more saturated and darker. `Affect Color` can be used to emulate this effect. At 0.0, this parameter has no effects.
## Affect Roughness
This parameter controls the roughness of the specular reflection, and specular transmission under the coating layer.
In the real world, refracted rays exhibit internal reflection within the coating medium, which can go back down to the underlying surface, which may scatter due to the roughness of the undercoating surface. `Affect Roughness` can be used to emulate this effect. At 0.0, this parameter has no effects.
# Base and Coat Layer
Coat Affect Roughness: 1.0
## Normal
This parameter sets the “normal direction” for the coating layer, which affects the Fresnel blending of the coating layer over the surface. The coat normal can create surface effects like raindrops, imperfections in car paint, or glazing on the food.
> **Note**
> The “coat normal” only affects the coating layer and has no effects on the underlying surface normal.

# Sheen (Specular retro-reflection)
Display Name | Name | Type | Default
--- | --- | --- | ---
Weight | specular_retro_reflection_weight | float | 0.0
Color | specular_retro_reflection_color | color | 1.0, 1.0, 1.0
Roughness | specular_retro_reflection_roughness | float | 0.3
This layer creates an energy-conserving retro-reflective sheen BRDF. Sheen simulates surface micro-fibers, with axes oriented parallel to the surface normal, creating specular highlights at grazing angles.
Sheen can create soft backscattering materials like fine powder, dust, satin, leaf, and peach fuzz on the skin.
## Weight
This parameter sets the density and length of micro-fibers. At 0.0, sheen has no effects.
### Sheen Weight: 0.0
### Sheen Weight: 1.0
## Color
This parameter tints the color of the sheen, i.e., micro-fibers.
### Sheen Color: 1.0, 1.0, 1.0
### Sheen Color: 0.75, 0.07, 0.45
## Roughness
This parameter sets the sheen effect roughness. Micro-fibers diverge more from the “surface normal” direction at a higher value, resulting in a softer look.
## Emission
### Display Name
### Name
### Type
### Default
| Display Name | Name | Type | Default |
|--------------|----------------|--------|---------|
| Weight | emission_weight| float | 0.0 |
| Emission Mode| emission_mode | enum | emission_lx |

This layer adds directionally uniform EDF under the coating layer, which describes the light-emitting properties of the surface.
It can create materials like an incandescent light-bulb, glowing lava, and LED panel.
### Note
In the RTX – Interactive (Path Tracing) mode, to reduce the noise in the indirectly lit area using emissive materials, one may need to increase the **Total Samples per Pixel**.
Please see RTX Interactive (Path Tracing) mode render settings for more information.
| Total Samples per Pixel: 8 | Total Samples per Pixel: 32 |
| --- | --- |
| Total Samples per Pixel: 128 | Total Samples per Pixel: 512 |
**Weight**
This parameter sets the amount of light emission from the surface.
| Emission Weight: 0.0 | Emission Weight: 0.5 |
| --- | --- |
| Emission Weight: 0.75 | Emission Weight: 1.0 |
**Emission Mode**
This parameter specifies the physical units to use for the emission intensity.
1. “Nit” is the unit of luminance and describes the surface power of a visible light source. The overall illumination of the scene changes depends on the size of the light source.
One nit is equal to one candela per square meter. 1 nit = 1 cd/m^2
The candela per square meter is the base unit of luminance. Candela is the base unit for luminous intensity.
A light source that emits one candela of luminous intensity onto an area of one square meter has a luminance of one candela per square meter or one nit. As an example, a calibrated monitor has a brightness of 120 cd/m^2 or 120 nits.
2. “Lux” is the unit of illuminance and describes the total amount of visible light that a light source emits. The overall illumination of the scene does not change depending on the size of the light source.
One lux is equal to one lumen per square meter. 1 lux = 1 lm/m^2
A light source that emits one candela of luminous intensity from an area of one steradian has a luminous flux of one lumen.
A light source that emits one lumen of luminous flux onto an area of one square meter has an illuminance of one lux. As an example, very bright sunlight has a brightness of 120,000 lux.
**Intensity**
This parameter sets the emission intensity. The emission mode parameter sets the physical unit for this parameter.
A few examples of illuminance under various lighting conditions:
| Lighting Condition | Illuminance (lx) |
| --- | --- |
| Sunlight | 100,000 - 120,000 |
| Daylight | 10,000 - 25,000 |
|----------|----------------|
| Overcast | 1000 |
| Twilight | 10 |
| Full moon | 0.05 – 0.3 |
| Ceiling lamp | 400 - 800 |
| Table lamp | 200 - 300 |
| Candle light | 12.57 |
**Color**
This parameter sets the emission color.
| Emission Color: Rainbow | Emission Color: Lava |
|-------------------------|----------------------|
**Use Temperature**
Enable the use of color temperature value instead of color.
::: note
**Note**
This parameter will override the default emission color, including any textures assigned to the emission color parameter.
:::
**Temperature (Kelvin)**
This parameter specifies emission color using a color temperature in the Kelvin unit. Lower values are warmer, i.e., redder, while higher values are cooler, i.e., bluer. The default value of 6500K is close to D65 illuminant, the white point in sRGB and Rec. 709 color spaces.
| Emission Temperature: 3200.0 | Emission Temperature: 5000.0 | Emission Temperature: 6500.0 |

| Use Temperature: Enabled | Use Temperature: Enabled | Use Temperature: Enabled |
## Thin Film
| Display Name | Name | Type | Default |
|--------------|--------------|------|---------|
| Enable Thin Film | enable_thin_film | bool | false |
| Thickness (nm) | [Thickness Value] | [Type] | [Default] |
| thin_film_thickness | float | 400.0 |
|---------------------|-------|-------|
| IOR Preset | thin_film_ior_preset | enum | ior_custom |
| IOR | thin_film_ior | float | 1.52 |
This layer models a reflective thin film when a metal and or specular reflection layer presents. Due to interference, a view-dependent iridescence effect occurs when the thin film layer thickness is close to the visible spectrum.
It can create materials like a peacock feather, burnt metal, soap bubble, and car paint.
**Enable Thin Film**
Enables thin film layer
**Thickness (nm)**
This parameter sets the thickness of the thin film layer in nanometers. At 0.0, the iridescence effect is disabled.
> **Tip**
> A typical soap bubble thickness is about 250 - 600 nanometers. By contrast, human hair thickness is in the range of 40,000 - 100,000 nanometers wide.
**IOR Preset**
This parameter presents a list of known IORs (index of refractions) for various materials, including glass, soap bubble, diamond. One can use custom IOR by setting this parameter to ior_custom and a value for the specular reflection’s IOR parameter.
**IOR**
This parameter sets the refractive index of the thin film layer.
> **Tip**
> The refractive index of water is 1.33, and a typical soap is 1.5. For a realistic result, the refractive index of the thin film should be less than soap and greater than water, i.e., 1.34 - 1.49.
## Geometry Section (Opacity, Geometry normal, Displacement)
| Display Name | Name | Type | Default |
|--------------------|-----------------|--------|---------|
| **Thin Walled** | thin_walled | bool | false |
| **Enable Opacity** | enable_opacity | bool | false |
| **Opacity** | geometry_opacity| float | 1.0 |
| **Opacity Threshold** | geometry_opacity_threshold | float | 0.0 |
| **Geometry Normal** | geometry_normal | float3 | state::normal() |
| **Displacement** | geometry_displacement | float3 | 0.0, 0.0, 0.0 |
### Thin Walled
This parameter sets the surface as an infinitely thin double-sided shell with a refraction index of the surrounding medium, so refracted rays exit immediately instead of entering the medium.
Thin-walled is ideal for geometrically thin objects, like a sheet of paper, soap bubble, and leaves.
**Note**
“Dispersion” has no effects when Thin-Walled enabled.
**Tip**
When Thin-Walled is enabled, “subsurface” is represented as the diffuse transmission of the light through an infinitely thin shell, i.e., translucence.
## Enable Opacity
Enables the use of opacity
## Opacity
This parameter controls the travel of rays through the surface. At 0.0, the surface is invisible to the cameras, while at 1.0, it is completely opaque.
It can create render-time geometric detail on low-resolution and thin geometries.
### Tip
Unlike transmission, renderers are optimized to use opacity to quickly skip over empty parts of a surface with a few operations.
## Opacity Threshold
This parameter controls the opacity threshold. At a value lower or equal to the opacity map, the surface renders completely transparent. At a value greater than the opacity, the surface renders fully opaque.
## Geometry Normal
This parameter replaces the surface geometric normal with the one evaluated from a map. “Geometry Normal” has no effects on the coating layer.
## Displacement
This parameter sets the direction and distance of position modification of the surface.
### Important
This feature is not supported yet.

## Melanin Concentration
### Blonde
- Melanin Concentration: 0.2
### Light Brown
- Melanin Concentration: 0.35
### Brown
- Melanin Concentration: 0.5
### Dark Brown
- Melanin Concentration: 0.75
### The Crow - Black
- Melanin Concentration: 1.0
## Melanin Redness (Pheomelanin)
This parameter sets the melanin redness, which is the ratio between brown eumelanin and red pheomelanin. At higher values, the hair fiber becomes redder. The melanin redness has no effects when the melanin concentration parameter is 0.0.
### Melanin Redness (Pheomelanin): 0.0
### Melanin Redness (Pheomelanin): 0.5
### Melanin Redness (Pheomelanin): 0.75
### Melanin Redness (Pheomelanin): 1.0
## Melanin Randomize
This parameter randomizes the amount of melanin concentration within hair fibers.
> **Note**
> The melanin randomization is not supported yet, one may map a texture noise to the melanin concentration parameter instead.
### Melanin Randomization: 0.0
### Melanin Randomization: 1.0
## Specular (Specular reflection)
| Display Name | Name | Type | Default |
| --- | --- | --- | --- |
| Roughness | specular_reflection_roughness | float | 0.2 |
| Anisotropic Roughness | specular_reflection_anisotropic_roughness | bool | false |
| Azimuthal Roughness | specular_reflection_azimuthal_roughness | float | 0.2 |
| IOR Preset | specular_reflection_ior_preset | enum | ior_custom |
| IOR | specular_reflection_ior | float | 1.55 |
| Shift (deg) | specular_reflection_shift | float | 3.0 |
This hair model classifies light paths based on the number of internal reflections. Light paths are named after their event type. The first three light paths are R, TT, and TRT, where R indicates a reflection and T a transmission event.
These primary light paths are modeled as separate lobes with a dedicated longitudinal and azimuthal roughness. In contrast, longer light paths are implicitly accounted for a fourth lobe without additional parameters.
While the fourth lobe needs no azimuthal roughness, the longitudinal roughness of the fourth lobe is set to longitudinal roughness of the “third lobe”.
**Roughness**
This parameter sets the longitudinal roughness of the reflection along the hair fiber. At 0.0, reflection becomes sharp and bright, while at 1.0, a deviation based on specular_reflection_shift in degrees, for a very rough reflection.
**Anisotropic Roughness**
This parameter enables the use of the azimuthal roughness parameter. When disabled, the roughness parameter controls both longitudinal and azimuthal roughness.
**Azimuthal Roughness**
This parameter sets the azimuthal roughness of the reflection in the hair fiber’s tangent direction when the anisotropic roughness parameter is enabled. At a lower value, the reflection looks sharp, while at a higher value, reflection wraps around the hair fiber, giving a smoother look.
One could consider azimuthal roughness as a phase function of the hair fiber’s volume, which changes the translucency and affects the multiple scattering albedo.
| Anisotropic Roughness: Disabled | Anisotropic Roughness: Enabled |
|----------------------------------|--------------------------------|
| Azimuthal Roughness: 0.0 | Azimuthal Roughness: 0.1 |
| Roughness: 0.2 | Roughness: 0.2 |
| Anisotropic Roughness: Enabled | Anisotropic Roughness: Enabled |
|----------------------------------|--------------------------------|
| Azimuthal Roughness: 0.3 | Azimuthal Roughness: 0.5 |
| Roughness: 0.2 | Roughness: 0.2 |
**IOR Preset**
This parameter presents a list of known IORs (index of refractions) for various materials, including hair and wet hair. One can use custom IOR by setting this parameter to ior_custom and a value for the specular reflection’s IOR parameter.
**IOR**
This parameter sets the index of refraction. Individual hair fibers are modeled as dielectric cylinders, with hair fiber reflecting off and transmitting into the fiber depending on the IOR.
At a lower IOR value, hair fibers exhibit strong forward scattering, while at a higher IOR value, stronger reflection.
> Tip: The IOR for typical human hair is about 1.55. A lower value can give hair fibers a muted look, while a higher value gives a wet look.
| Muted and thick hair | Wet hair |
|----------------------|----------|
| IOR: 1.2 | IOR: 1.8 |
**Shift (degree)**
This parameter sets the angle of the hair fiber’s scales. values above 0.0 shift the primary and the secondary specular reflections away from the hair fiber’s root, while values less than 0.0 shift the specular reflection toward the root.
Recommended values for human hair:
| Hair Origin | Scale angle (degrees) |
|-------------|-----------------------|
| Piedmont | 2.8 ± 0.2 |
| Light brown European | 2.9 ± 0.3 |
| Dark brown European | 3.0 ± 0.2 |
| Indian | 3.7 ± 0.3 |

| Weight | diffuse_reflection_weight | float | 0.0 |
| Color | diffuse_reflection_color | color | 1.0, 1.0, 1.0 |
It adds a Lambertian diffuse component for greater control over the look of hair fibers.
**Weight**
This parameter sets the weight of the additional diffuse reflection component. At 0.0, the hair fiber exhibits specular scattering, while at 1.0, completely diffuse scattering.
> Note
> A healthy-looking human hair fiber does not have any diffuse component. However, the diffuse component can create effects such as makeup, dirty or damaged hair, and fabric threads.
**Color**
This parameter sets the color of the diffuse scattering component.
## OmniHairBase Emission
### Emission
| Display Name | Name | Type | Default |
|--------------|---------------|--------|---------|
| Weight | emission_weight | float | 0.0 |
| Emission Mode | emission_mode | enum | emission_lx |
| Intensity | emission_intensity | float | 1.0 |
| Color | emission_color | color | 1.0, 1.0, 1.0 |
| Use Temperature | emission_use_temperature | bool | false |
| Temperature | emission_temperature | float | 6500.0 |
This layer adds an additional directionally uniform EDF, which describes the light-emitting properties of the surface.
> **Note**
> Realistic hair fibers do not have any emissive property, and these are just for artistic control.
> **Note**
> In the RTX – Interactive (Path Tracing) mode, to reduce the noise in the indirectly lit area using emissive materials, one may need to increase the **Total Samples per Pixel**. Please see [RTX Interactive (Path Tracing) mode render settings](rtx-renderer_pt.html) for more information.
### Weight
This parameter sets the amount of light emission from the surface.
### Emission Mode
This parameter specifies the physical units to use for the emission intensity.
<em>
and describes the surface power of a visible
light source. The overall illumination of the scene changes depends on the size
of the light source.
</em>
One nit is equal to
<em>
one candela per square meter
</em>
. 1 nit = 1 cd/m^2
The candela per square meter is the base unit of
<em>
luminance
</em>
.
<em>
Candela
</em>
is the
base unit for luminous intensity.
A light source that emits one candela of luminous intensity onto an area of one
square meter has a luminance of one candela per square meter or one nit. As an
example, a calibrated monitor has a brightness of 120 cd/m^2 or 120 nits.
2. “Lux” is the unit of
<em>
illuminance
</em>
and describes the total amount of visible light
that a light source emits. The overall illumination of the scene does not change
depending on the size of the light source.
One lux is equal to
<em>
one lumen per square meter
</em>
. 1 lux = 1 lm/m^2
A light source that emits one candela of luminous intensity from an area of one
steradian has a luminous flux of one lumen.
A light source that emits one lumen of luminous flux onto an area of one square
meter has an illuminance of one lux. As an example, very bright sunlight has a
brightness of 120,000 lux.
**Intensity**
This parameter sets the emission intensity. The emission mode parameter sets the
physical unit for this parameter.
A few examples of illuminance under various lighting conditions:
| Lighting Condition | Illuminance (lx) |
|--------------------|------------------|
| Sunlight | 100,000 - 120,000 |
| Daylight | 10,000 - 25,000 |
| Overcast | 1000 |
| Twilight | 10 |
| Full moon | 0.05 – 0.3 |
| Ceiling lamp | 400 - 800 |
| Table lamp | 200 - 300 |
| Candle light | 12.57 |
**Color**
This parameter sets the emission color.
**Use Temperature**
Enable the use of color temperature value instead of color.
> **Note**
> This parameter will override the default emission color, including any
> textures assigned to the emission color parameter.
**Temperature**
This parameter specifies emission color using a color temperature in the Kelvin
unit. Lower values are warmer, i.e., redder, while higher values are cooler,
i.e., bluer. The default value of 6500K is close to D65 illuminant, the white
point in sRGB and Rec. 709 color spaces.
## Geometry (Opacity, Geometry normal, Displacement)
| Display Name | Name | Type | Default |
|--------------|---------------|--------|---------|
| Enable Opacity | enable_opacity | bool | false |
| Opacity | geometry_opacity | float | 1.0 |
| Opacity Threshold | geometry_opacity_threshold | float | 0.0 |
| Geometry Normal | geometry_normal | float3 | state::normal() |
| Displacement | geometry_displacement | float3 | 0.0, 0.0, 0.0 |
### Enable Opacity
Enables the use of opacity
### Opacity
This parameter controls the travel of rays through the surface. At 0.0, the surface is invisible to the cameras, while at 1.0, it is completely opaque.
#### Note
Although it is not physically correct, one may reduce the opacity to create softer-looking hair fibers at the cost of increased render time.
| Full Look | 50% Hair-Thinning |
|-----------|------------------|
| Opacity: 1.0 | Opacity: 0.5 |
| 75% Hair-Thinning | Haircut |
|------------------|---------|
| Opacity: 0.25 | Opacity: Texture |
## Opacity Threshold
This parameter controls the opacity threshold. At a value lower or equal to the opacity map, the surface renders completely transparent. At a value greater than the opacity, the surface renders fully opaque.
## Geometry Normal
This parameter replaces the surface geometric normal with the one evaluated from a map.
## Displacement
This parameter sets the direction and distance of position modification of the surface.
### Important
This feature is not supported yet.
## Presets
OmniHarBase comes with an existing library of presets. These presets can be used as a starting point for creating a new hair look.
| Black | Auburn |

## Color Space
Texture Slots in Omniverse Apps contain a dropdown allowing the selection of color-space. Choosing the correct color space is critical to correct visual output and should be set to match the Color Space of the image being used. As a general rule, data images like Normal, Roughness, Metallic, etc. are best using RAW while full color images like Base/Diffuse Color should be set to sRGB. Auto can be used to help guess the color space but should be used cautiously as it can guess incorrectly based on several factors.
| Color Space | Result |
|-------------|--------|
| Auto | Assigns the Color Space based on metadata or bit depth of the image. Checks for gamma or color space metadata in the texture file. If the texture is 8-bit or has 3 channels or if it is 8-bit and has 4 channels, the image is read in sRGB. Otherwise read the image in RAW. |
| sRGB | Applies sRGB to Linear color transformation. |
| RAW | Uses texture data as it’s read from the file. |
## Applying Materials
In order to assign a material to an object, the material must be added to your stage. This can be accomplished several ways. Using drag and drop, you can drag your material to an empty part of the Viewport or to the Stage panel. If you wish to use one our the Omniverse materials, you can use the Create menu.
Once a material is in the scene, the material can be assigned to any location. With your object or scene location selected, you can assign the material by going to the Details panel and selecting your material in the dropdown under **Materials on selected models**. If an scene has multiple material, a searchable list box will open so you can select the appropriate material to assign. You can scroll through the list of materials or type the name or partial name of your material.
## Apply a Material to a Mesh
1. Select the mesh you want to apply a material to.
2. In the details panel look for the heading “Materials on selected models”
3. In the dropdown under that heading select the material you wish to apply.
4. At this point your material is applied to the selected mesh and adjustment of the material inputs should present themselves as changes occur.
## Search Material List
Sometimes the dropdown list can become exhaustive in length, a search widget found at the top of the dropdown can help alleviate this issue.
While menu dropped down:
> 1. Select Search bar at top top of drop-down panel.
> 2. Type character string in material name.
> 3. Select appropriate material.
## Drag and Drop Assignment
In Omniverse USD Composer, materials can be dragged from the stage and dropped onto assets or prims based on the selection mode you are in.
- If you have Object Selection Mode enabled, dragging a material from the stage onto an object will replace the material of ALL prims that make up the selected asset.
- If you have Prim Selection Mode, dragging a material from the stage to an object will replace the prim where the material is dropped.
## Creating Materials
Materials can be easily created in Omniverse USD Composer using the Create > Materials menu.
Creating materials can be done in 2 common ways.
#. Create a material on a mesh : This method is when you want to create a material in your scene AND apply it to selected meshe(s).
#. Create a Material in a scene : This method simply creates a material inside the scene’s look folder but does NOT apply it to a mesh.
> IF your model does not have UVs, you will need to enable “World Space UV” to display textures.
### Create Material on Mesh
For a quick easy way to apply a new material to your mesh you can create and automatically apply the material by simply selecting a mesh or several meshes before creating a new material.
1. Select the mesh you want to apply a material to.
2. Select Create > Material > Omni PBR, Omni Glass, etc.
3. In the status bar (bottom right of screen), you will likely see a 0% bar for a few moments. Wait until it completes and disappears to confirm it is fully loaded.
4. In the Stage window, Select the Looks folder and Find the shader you selected (ie: Omni PBR). Feel free to rename this as desired.
5. If the material is fully loaded, you should see inputs for the material in the Details panel.
6. At this point your material is applied to the selected mesh and adjustment of the inputs should present themselves as changes occur.
### Create Material in Scene
There are times when you may want to pre-build a series of MDL’s and you do not want to select the meshes each time as a needed step. In this case, you can simply create the materials first, fill them in, and later apply the materials to selected objects.
1. Deselect all by left clicking a blank area in either the Stage or the Viewport.
2. Select Create > Material > Omni PBR
3. In the status bar (bottom right of screen), you will likely see a 0% bar for a few moments. Wait until it completes and disappears to confirm it is fully loaded.
4. In the Stage window, Select the Looks folder and Find the shader you selected (ie: Omni PBR). Feel free to rename this as desired.
5. If the material is fully loaded, you should see inputs for the material in the Details panel.
6. You can now fill in the materials input properties as needed to set it to your desired materials look however it has not been applied yet and will not display.
## Material Selection
As materials are an intricate part of the visual process, Omniverse USD Composer has several selection methods for working with Materials.
### Looks
Whenever a material is added to a scene, it will be stored in a “looks” directory in your Stage. This is where all material references are shown and managed.
> When a USD is nested, it will carry its looks folder with it. Therefore it is possible to have several looks folders in the appearing in stage, one for each imported USD is possible.
### Scene Material Quick Linking
With an asset selected, Click the arrow to right of material input to “jump” to the bound material.
## Locate MDLs on your Nucleus
Floating MDLs (MDLs existing in a reachable Nucleus Path) can be quickly located from the stage.
Select a **Shader** in the scene and locate the Details panel.
Select the Right Arrow next to the module will quickly jump the Content Browser to the MDLs location on the nucleus.
Using the Folder icon will allow reassignment to a different MDL.
Note: Locating MDLs with this method only works if your material exists on the Nucleus, therefore materials generated from the “Create” panel will not be located by this method as they exist as direct system references and not a particular location.
## Finding Objects attached to a Material
Selecting all objects bound with a specific material in your current scene can be quite useful at times.
In the Stage, Right Click on a material and choose “Select Bound Objects”.
## Material Swap
Allows you quickly swap one material for another while maintaining any USD connections for the target material.
### Choose a Target Material
To use the material swap tool, simply select a material you wish to replace in your content browser, then while highlighted, select “User Selected”. The Material to replace input window should now reflect the path to the material you expect to replace.
### Choose a Source Material
Next, choose a material in your browser you wish to use to replace. Press User Selected again to populate the input with the path to the source material.
### Swap
Once swapped, the target material should now have the same properties and settings as the source material. Any assets using this material will be updated.
## UDIM Support
### Overview
Omniverse USD Composer has UDIM support done in a way that is both convenient and powerful. By using the standard naming conventions used in a typical UDIM scenario, you simply replace the UDIM number with `<UDIM>` on ANY texture file input to invoke UDIM support.
### Using UDIM’s in Omniverse USD Composer (Video)
### Drag and Drop assignment of UDIM sequences
By default, file sequences of UDIM textures are displayed in the Content Browser as discreet file names and thumbnails. UDIM sequences can be displayed compactly through the Options dialog. Enabling **Display UDIM Sequence** displays the sequence as a single file name with the UDIM tile numbers replaced with the UDIM token. Dragging and dropping the sequence to a texture parameter on a material inserts the sequence into the material.
To open Options, click the 3 lines in the upper right of the Content Browser. **Display UDIM Sequence** is persistent and will save with your configuration.
Manually replacing the UDIM frame number with the UDIM token is still applicable to any MDL parameter texture input.
### Example UDIM Sequence
If you have a sequence of textures slated for use in a UDIM prepared mesh like this…
```
my_texture.1001.png
my_texture.1002.png
my_texture.1003.png
```
Simply replace the number with `<UDIM>` in any MDL texture input dialogue.
```
my_texture.<UDIM>.png
```
Note: Using UDIMs instead of multiple material assignments can benefit larger scenes/meshes by easing the assignment of a multitude of textures by its naturally automated process.
## Primvars
Primvars are additional data attached to a geometric object. The data is defined as a USD token and value pair and can be accessed using an MDL data_lookup node in the Material Editor. The data can then be used to drive shading parameters for rendering.
## Expanding Your Library
You can expand your library of MDLs by writing your own custom MDLs and importing them. You can also use Substance Designer to develop MDLs using a visual interface.

mdl-in-omniverse_Overview.md | # Overview — Omniverse Kit 52.0.1 documentation
## Overview
The Omni MDL extension provides access to the MDL SDK Python bindings. This low-level binding is automatically generated from the C++ API using SWIG. With only a limited number of exceptions, it offers the same functionality as the native API using a nearly identical set of functions and classes. For detailed API documentation, examples, and the source code, please consult:
- NVIDIA Ray Tracing Documentation
- NVIDIA MDL Github
### MDL in Omniverse
The MDL SDK relies on the neuray API which is shared with the NVIDIA Iray renderer. At its core, there is a database that stores the MDL modules, their definitions, and calls. Calls are instantiated function definitions along with their parameters. Since parameters can reference other calls, they describe entire material graphs that correspond to the USD materials composed of USD shader nodes. This means that MDL provides the implementation of the abstract material description in USD.
The binding itself is independent of Omniverse and Kit. To be able to work on the same database as Omniverse, another extension, called omni.mdl.neuraylib, is used.
Getting an `INeuray` instance is the first step for all MDL SDK development:
```python
import omni.mdl.pymdlsdk as pymdlsdk # low-level MDL python binding that matches the native SDK
import omni.mdl.neuraylib # interface the OV material backend
# acquire the neuraylib instance from OV
ov_neuray_lib = omni.mdl.neuraylib.get_neuraylib()
# feed the neuray instance handle into the python binding
ov_neuray_handle = ov_neuray_lib.getNeurayAPI()
neuray: pymdlsdk.INeuray = pymdlsdk.attach_ineuray(ov_neuray_handle)
```
For accessing the materials used by the active renderer, an `ITransaction` is needed. Instead of creating the transaction directly using the `IDatabase` component, call the `omni.mdl.neuraylib` functions for proper interop with Omniverse.
```python
# acquire the neuraylib instance from OV
ov_neuray_lib = omni.mdl.neuraylib.get_neuraylib()
# create a transaction after loading so we we can see the loaded module
# we also request a handle from omni.mdl.neuraylib to initialize an omni.mdl (Python Binding) transaction.
ov_transaction_handle = ov_neuray_lib.createReadingTransaction()
transaction: pymdlsdk.ITransaction = pymdlsdk.attach_itransaction(ov_transaction_handle)
```
## Python Usage
For a more complete example, please see the Python usage page.
## User Guide

### CHANGELOG |
Memory.md | # DLL Boundary Safe Memory Management
Passing pointers across DLL boundaries could lead to heap corruption if the DLLs use different runtimes. Each runtime has its own heap manager, so attempting to free memory in a DLL that was allocated in a different DLL is unsafe. However, it is desirable to be able to pass pointers, or objects that contain pointers (such as a string), across DLL boundaries. In order to achieve this, Carbonite provides memory management functions that are DLL-boundary-safe.
There are three available functions: `carb::allocate()`, `carb::deallocate()`, and `carb::reallocate()`. These functions are analogous to `malloc`, `free`, and `realloc`. These functions all use an internal memory management function in `carb.dll`/`libcarb.so` ( `carbReallocate()` ), so that all allocations and deallocations use the same C Runtime, and thus are safe for use by different plugins.
## Linking
The functions mentioned above are `inline` functions that all depend on a function (`carbReallocate()`) located within the Carbonite dynamic library (`carb.dll`/`libcarb.so`). Using these functions means that the Carbonite dynamic library must be loaded before the functions can be called.
However, the default definition of this function is weakly-linked, meaning that it is possible to build plugins which implicitly require the Carbonite dynamic library to be loaded without the hassle of explicitly linking against Carbonite’s import library or dynamic library. If strong linking is required (i.e. for an application using allocation functions prior to loading the Framework), `CARB_REQUIRE_LINKED` may be set prior to including `carb/memory/Memory.h`. |
Menu.md | # Visual Scripting Menus
## Window -> Visual Scripting
OmniGraph functionality appears in a few of the main menus. The first one is in the *Window* menu, and it lists the available UI panels and windows that can be opened for interacting with OmniGraph.
Both the *Action Graph* and *Generic Graph* entries will open up one of the [Visual Graph Editors](GraphEditors.html#omnigraph-graph-editors) window in which you can create and modify an OmniGraph.
The *Node Description Editor* entry directs you to a window in which you can visually create an extension and framework for Python nodes, including the .ogn file and a template for your node implementation. The [Node Description Editor](NodeDescriptionEditor.html#omnigraph-node-description-editor) is experimental and temporary, however you can use it as a gentle introduction to the world of node writing.
The *Toolkit* entry opens a window containing a debugging interface for users that want to peek into some of the internals of OmniGraph. Inside the [Toolkit](Toolkit.html#omnigraph-toolkit) you will find entries that allow you to inspect various facets of the OmniGraph data. The contents of the window evolve as new features are introduced.
## Create -> Visual Scripting
In order to support a more consistent experience when creating new objects OmniGraph has added an entry into the *Create* menu that enables creation of simple OmniGraph types.
Through this menu you can create new instances of the three main types of OmniGraph - [Action Graph](../Glossary.html#term-Action-Graph) , [Push Graph](../Glossary.html#term-Push-Graph) , and [Lazy Graph](../Glossary.html#term-Lazy-Graph) . The difference between them lies only in their primary method of evaluation. An [Action Graph](../Glossary.html#term-Action-Graph) will evaluate when triggered by an event. A [Push Graph](../Glossary.html#term-Push-Graph) will evaluate every time the application updates, or “ticks”. A [Lazy Graph](../Glossary.html#term-Lazy-Graph) will evaluate only the subsection of a graph that has changed since the last evaluation.
## Edit -> Preferences
Like many other subsystems, OmniGraph has a set of user-configurable settings. They can be found in the *Visual Scripting* panel of the *Preferences* window.
| Edit Preferences Menu | Visual Scripting Panel |
| --- | --- |
|  |  |
## Settings Editor
## Window -> Property and Window -> Stage
These two menu entries, though normally applied to USD stages and prims, have specialized features added to support OmniGraph.
In the stage window you can see the special icon that indicates an OmniGraph prim definition. Different colors indicate different graph types - green for Action Graph, pink for Push Graph, and yellow for Lazy Graph. The prim types are **OmniGraph** for the main graph prim, and **OmniGraphNode** for the prims below it that correspond to nodes in the graph.
In the property panel the prim properties are divided into three sections when OmniGraph nodes are present. The top section “**OmniGraph Node**” represents the OmniGraph-specific interface to the attribute values, explained in Property Panel. The middle section “**Compute Graph**” is an OmniGraph-centric representation of the attributes on the node. The lower section “**Raw USD Properties**” presents the prim’s property values as USD sees them.
In many cases the contents of the bottom two sections will be very similar but occasionally a node will not store some of its data in USD, only storing it as temporary data in Fabric. |
MenuLayout.md | # Menu Layout
This extension adds support for menu layout on demand.
Menu layout defined with omni.kit.menu.utils.MenuLayout could be replaced with [[settings.exts."omni.app.setup".menu_layout]] in kit file.
For example:
```c++
layout_menu = [
MenuLayout.Menu(
"Layout",
[
MenuLayout.Item("Default", source="Reset Layout"),
MenuLayout.Item("Viewport Only"),
MenuLayout.Seperator(),
MenuLayout.Item("Save Layout", source="Window/Layout/Save Layout..."),
MenuLayout.Item("Load Layout", source="Window/Layout/Load Layout..."),
MenuLayout.Seperator(),
MenuLayout.Seperator(),
MenuLayout.SubMenu("Utilities", [
MenuLayout.Group("Viewport", source="Window/Viewport"),
]),
],
),
MenuLayout.Menu(
"Window",
[
MenuLayout.SubMenu("Layout", [
MenuLayout.Item("Quick Save", remove=True),
MenuLayout.Item("Quick Load", remove=True),
]),
MenuLayout.Sort(exclude_items=["Extensions"], sort_submenus=True),
]
)
]
```
could be replaced with:
```toml
[settings.exts."omni.app.setup".menu_layout.Layout]
```
items = [
"Default=Reset Layout",
"Viewport Only",
"",
"Save Layout=Window/Layout/Save Layout...",
"Load Layout=Window/Layout/Load Layout...",
"",
"Utilities",
]
Utilities.type = "SubMenu"
Utilities.items = ["Viewport=Window/Viewport"]
Utilities.Viewport.type = "Group"
[settings.exts."omni.app.setup".menu_layout.Window]
items = ["Layout", "sort"]
Layout.type = "SubMenu"
Layout.items = ["-Quick Save", "-Quick Load"]
sort.type = "Sort"
sort.exclude_items = ["Extensions"]
sort.sort_submenus = true |
MenuOrder.md | # Root Menu Order
This extension adds support for root menu order on demand.
Menu order can be specified in `[[settings.exts."omni.app.setup".menu_order]]` sections.
For example:
```toml
[settings.exts."omni.app.setup".menu_order]
window = -7
Tools = 80
Layout = 90
Help = 100

## Kit Extensions Upgrade
This section on upgrading Kit extensions contains information about breaking changes necessary to get building.
A fair amount of the toolset that we build on has been upgraded. This includes a new version of Visual Studio (2019), Boost 1.76, Python 3.10 and USD 22.11. These changes do impact Kit Extension developers and this next section will walk through some of the changes needed to upgrade an Extension to support all these changes.
The following steps assume that your Kit Extension is based on the Kit Extensions Template. The steps here should help the upgrade process but might be different depending on how the repository is set up to build.
### Visual Studio 2019
The first step is to make sure your Extension is compatible with Visual Studio 2019.
- Update your host-deps.packman.xml
- Change your premake dependency to a more recent version. Currently, this is “5.0.0-beta1+nv1-${platform}”
- Make your msvc dependency compatible with Visual Studio 2019. Currently, this is “2019-16.11.17-2”
- Also use an updated version of winsdk which is “10.0.19608.0”
- Next, you’ll need to update your version of repo_kit_tools in repo-deps.packman.xml. This updated version is needed so that premake will use the Visual Studio 2019 generator during the build process. This will require repo_kit-tools version 0.9.4 or later
These updated dependencies should get the Extension repository pulling in the necessary dependencies for a Windows build using Visual Studio 2019
**NOTE:** An issue was encountered where the Extension(s) would still issue Windows build errors if built from a normal Windows Command Prompt. Switching to a Visual Studio 2019 Command Prompt fixed the issue. The exact build error was:
```shell
TRACKER : error TRK0005: Failed to locate: "CL.exe". The system cannot find the file specified.
C:\omniverse\kit-ext-tpl-cpp-int\_compiler\vs2019\omni.example.cpp.commands.tests\omni.example.cpp.commands.tests.vcxproj
TRACKER : error TRK0005: Failed to locate: "CL.exe". The system cannot find the file specified.
C:\omniverse\kit-ext-tpl-cpp-int\_compiler\vs2019\omni.example.cpp.commands.plugin\omni.example.cpp.commands.plugin.vcxproj
```
### Issues with USD
The main issue that we are aware of when building a USD plugin, such as a SdfFileFormat plugin, against Visual Studio 2019 is an optimization that the compiler makes with release builds. Visual Studio 2019 enables the “/Zc:inline” option by default, we need to make sure that this option is disabled otherwise USD will not be able to construct your USD plugin in a release build.
- In premake.lua make sure that you add the ”/Zc:inline-” buildoption for release builds to disable that behavior
- If you are curious about why this needs to be done you can read more about the issue [here](#kit-sdk)
### Kit SDK
Next, we’ll need to point our Extension at a kit-sdk dependency that includes all the changes necessary for Usd 22.11 and Python 3.10:
The kit-sdk dependency is usually declared within kit-sdk.packman.xml if using the Kit Extension Template
- **kit-sdk@105.0.1**
- 105.0.1+release.109439.ed961c5c.tc.${platform}.${config}
- **kit-sdk@105.1**
- 105.1+master.121139.5d3cfe78.tc.${platform}.${config}
We will also need to correctly import these new upstream dependencies from our kit-sdk dependency:
- In target-deps.packman.xml (or kit-sdk-deps.packman.xml) make sure that you are importing both the python and nv_usd dependencies from kit-sdk
- Make sure that your import path is pulling from all-deps.packman.xml in Kit
- filter to include “python”
- filter to include “nv_usd_py310_${config}”
This only needs to be added or changed if you extension depends on nv_usd. So if you see a dependency like nv_usd_py37_${config} make sure that it is updated to nv_usd_py310_${config}
At a minimum, your target-deps.packman.xml should be updated to look something like:
- If you are pulling your nv_usd or python dependencies directly, it might be a good time to update your dependencies and import directly from Kit’s all-deps.packman.xml. This will help align versions of Python and USD with the supported version of Kit for your Extension. For example, if you are declaring your python and nv_usd dependencies like the following:
```xml
<project toolsVersion="5.6">
<dependency name="nv-usd_${config}" linkPath="../_build/deps/usd_${config}">
<package name="nv-usd" version="20.08.nv.1.2.2404.6bf74556-win64_py37_${config}-main" platforms="windows-x86_64"/>
<package name="nv-usd" version="20.08.nv.1.2.2404.6bf74556-linux64_py37-centos_${config}-main" platforms="linux-x86_64"/>
<package name="nv-usd" version="20.08.nv.1.2.2404.6bf74556-linux-aarch64_py37_${config}-main" platforms="linux-aarch64"/>
</dependency>
<dependency name="python" linkPath="../_build/deps/python">
<package name="python" version="3.7.12+nv1-${platform}" platforms="windows-x86_64 linux-x86_64 linux-aarch64"/>
</dependency>
</project>
```
- Both python and nv_usd dependencies should be updated to use importing, i.e:
```xml
<project toolsVersion="5.6">
<import path="../_build/${platform}/${config}/kit/dev/all-deps.packman.xml">
<filter include="python"/>
<filter include="nv_usd_py310_${config}"/>
</import>
<dependency name="nv_usd_py310_${config}" linkPath="../_build/target-deps/nv_usd/${config}"/>
</project>
```
## Update premake lua
We should have all of the necessary dependencies for MSVC 2019, Python 3.10, Boost 1.76 and USD 22.11 correctly set up. The next part of the process is updating the premake.lua scripts for each extension. Unfortunately, each one of these premake.lua scripts can be different depending on what’s required to build the extension. For example, if your extension is purely Python no changes to premake.lua should be necessary. But if your extension depends on USD and links against Boost for Python bindings it’s very likely that premake.lua will need to be updated
### Update Python Include Paths or Links
If you have an Extension that creates Python bindings for a Native Extension, you’ll more than likely need to tweak some include paths and links in premake.lua.
- In premake.lua for each Extension search for usages of “python3.7” and update to “python3.10”. Typically, these will be limited to “includedirs” and “links” in premake.
- This should be as simple as search and replace but YMMV with complex build scripts.
- The important part is that the Python 3.10 headers and binaries can be found when you go to build / link your Extension.
### Update Boost Links
If the Extension you are building depends on Boost, include paths and links might need to change. This is definitely the case with Windows as the DLL includes the MSVC toolset along with the Boost version number in its name. These values are now vc142 and 1_76, respectively.
- For convenience, the link_boost_for_windows function can be used. When calling “link_boost_for_windows({“boost_python310”})” that should correctly link against Boost for Python 3.10 using the vc142 toolset.
### Common Errors
The location of the omni.usd binary has changed. To properly link against omni.usd you will need to change the library path to find it:
- libdirs {"%{kit_sdk}/extscore/omni.usd.core/bin"} -> libdirs
- **Unable to find Python headers / library for building Python bindings**
- The following error usually means that an include directory within a premake5.lua build script might be misconfigured and not set to the correct directory
- **Within your premake5.lua scripts a couple examples of incorrect paths:**
```lua
includedirs { target_deps.."/python/include/python3.10**m**" }
includedirs { target_deps.."/python/include/python3.7m" }
includedirs { target_deps.."/python/include/python3.7" }
```
- **These include directories should be set to the following now that Kit is using Python 3.10**
```lua
includedirs { target_deps.."/python/include/python3.10" }
```
## Usd 22.11 and Python 3.10 Updates
From here, the Extension repository should at least be able to find all the necessary dependencies, build and link against them. The next part will be to make any necessary changes for Python 3.10, such as calling `super().__init__()`, and USD 22.11. These changes can vary wildly between repositories and developers should refer to all the documentation in this guide on how to properly migrate their repository.
## 22.08
- Added the apiSchemaOverride feature to usdGenSchema that allows a schema definition to explicitly define sparse overrides to properties it expects to be included from a built-in API schema.
## 22.05
- Changes for usdGenSchema:
- Disabled inheritance for multiple apply API schemas, now that built-in API schemas are supported for multiple apply schemas.
- Fixed issue where schema tokens with invalid C++ identifiers would be generated. These tokens will now be converted into a valid identifier. Tokens beginning with a numeral are now prefixed with ‘_’.
- Added ability to generate C++ identifiers using property names and values exactly as authored in schema.usda instead of camel-casing them by specifying useLiteralIdentifier in the GLOBAL schema metadata. This is helpful in scenarios where schema.usda is generated using utilities like usdgenschemafromsdr instead of being hand authored.
- Fixed Python 3 compatibility by explicitly included the None keyword in reserved list.
## 22.03
- Changes for applied API schemas:
- Multiple-apply API schemas can now include other multiple-apply API schemas as built-ins.
- `"prepend apiSchemas"` must be used in schema.usda to set built-in API schemas on another schema.
- Applied API schemas authored on a prim can no longer change the type of a property defined by that prim’s type or built-in API schemas.
## 21.11
- Updated connectedAPIBehavior so that APISchemas can now provide connectableAPIBehavior by explicitly registering a new behavior associated with the APISchemaType or by providing plug metadata to configure the connectability behavior. Note that the latter can be used for codeless schemas.
- Single apply API schemas can now include built-in API schemas and can auto apply to other single apply API schemas. API schemas are now only allowed to inherit directly from UsdAPISchemaBase.
- Applied API schemas can no longer inherit from other other applied API schemas, which allows UsdPrim::HasAPI() to be a much faster query. Non-applied schemas may still inherit from other non-applied schemas.
## 21.08
- Added support for “codeless” USD schemas that do not have any C++ or Python code. Changes to these schemas’ definitions do not require any code to be recompiled; instead, the generatedSchema.usda just needs to be regenerated via usdGenSchema and reinstalled.
- Added ability to specify allowed prim types for API schemas in the customData dictionary for the schema in schema.usda.
- Added UsdPrim::CanApplyAPI and CanApply to all API schema classes to check if an API schema can be applied to a prim based on the restrictions above.
- API schemas can now provide connectability behavior, which can override behavior based on prim type.
## 21.05
- Updated usdGenSchema to not error when generating a dynamic schema and libraryPath is not specified.
- Fixed usdGenSchema to honor apiName metadata for auto generated tokens.h. This results in correct doxygen documentation for the correct API names.
- usdGenSchema now adds a type alias for abstract typed schemas, which means abstract typed schemas now have an official USD type name which is registered with the UsdSchemaRegistry.
- Auto apply API schemas in USD can now specify abstract typed schemas to auto apply to, indicating that the API should be applied to all schemas that derive from the abstract schema type.
## 21.02
- Added support for auto-apply API schemas. This allows single-apply API schemas to be automatically applied to prims using one of a list of associated concrete schema types instead of requiring the user to manually apply the API schema.
- Renamed UsdSchemaType to UsdSchemaKind to disambiguate between the schema type (e.g. UsdGeomSphere) and kind (e.g. non-applied, single-apply, etc).
- Deprecated functions using the "schema type" terminology in favor of "schema kind".
## Breaking Change: Applied API Schemas, Inheritance, and Built-Ins
As of v21.11, USD no longer supports inheritance chains for API schemas (although still fully supported for IsA schemas). The primary reason for this breaking change was the need to make `UsdPrim::HasAPI<SchemaType>()` more efficient by not continuously checking derivation chains. To that end, support for inheritance was removed from API schemas. Instead, API schemas have the ability to define built-ins, which are semantically similar to defining inheritance chains, but more performant from a USD run-time perspective.
Unfortunately, this has a significant impact to our own custom schema
definitions (particularly physics) and requires that these schemas be
migrated to conform to the new requirements.
## Inheriting `</APISchemaBase>` and Applying Built-Ins To Represent Dependencies
All API schema types (both single and multiple-apply) are now required to inherit `</APISchemaBase>`. This means that any derivation chains that exist in applied API schemas must be converted such that the inherits attribute of the schema type is `</APISchemaBase>`:
```c++
class "MyAppliedAPI" (
inherits = </APISchemaBase>
) {
}
```
To simulate inheritance and define a dependency chain, USD has introduced the concept of built-ins. This is the inverse of the auto-applied API schema feature - when an applied API schema is applied to a prim instance, all applied API schemas declared as built-ins are applied as well. Built-ins work recursively such that if SchemaType1API declared built-ins of SchemaType2API and SchemaType3API, and SchemaType2API declared built-ins of SchemaType4API, then applying SchemaType1API to a prim instance will also apply SchemaType2API, SchemaType3API, and SchemaType4API.
> All built-ins specified must be either single-apply API or named instances of multiple-apply API schemas (IsA schemas cannot be built-ins).
Declaring an applied API schema type as a built-in involves placing it’s schema type name in the prepend apiSchemas attribute of the schema type that uses it as a built-in:
```c++
class "ExampleSchema1API" (
inherits = </APISchemaBase>
customData = {
token apiSchemaType = "singleApply"
}
prepend apiSchemas = ["ExampleSchema2API"]
) {
}
```
This definition states that when ExampleSchema1API is applied to a prim instance, ExampleSchema2API will also be applied as a schema built-in to ExampleSchemaAPI. This mimics inheritance in the sense that applying ExampleSchema1API will always also apply ExampleSchema2API, so all attributes from both will be present on the prim (as you would expect in the normal inheritance chain).
**Note: A schema can have a stronger opinion on a property that may come from one of its built-ins if it declares the property itself. This is useful to override the default value of the property. Be careful not to do this unintentionally and do things like e.g. change the type of the property!**
Multiple-apply schemas have an additional set of consequences since they must always be applied to a prim instance using the same instance name. This results in the following:
- If a multiple-apply API schema is listed as a built-in without an instance name, it is always applied to the prim instance using the same instance name as the schema type declaring the built-in.
- If a multiple-apply API schema is listed as a built-in with an instance name, it will be applied with a suffixed instance name that combines the built-in instance name and the instance name of the schema type declaring the built-in.
For example, consider the following definition:
```c++
class "MultipleApplySchema1API" (
inherits = </APISchemaBase>
customData = {
token apiSchemaType = "multipleApply"
}
prepend apiSchemas = ["MultipleApplySchema2API"]
) {
}
```
Applying MultipleApplySchema1API to a prim instance with the instance name foo will also result in MultipleApplySchema2API being applied to the prim instance with the instance name foo. Now consider a slight modification to this definition:
```c++
class "MultipleApplySchema1API" (
inherits = </APISchemaBase>
customData = {
token apiSchemaType = "multipleApply"
}
prepend apiSchemas = ["MultipleApplySchema2API:bar"]
) {
}
```
In this case, applying MultipleApplySchema1API to a prim instance with the instance name foo will result in MultipleApplySchemaAPI2 being applied to the prim instance with the instance name foo.
applied with the suffixed instance name foo:bar.
Note that built-ins apply to IsA schema types as well (that is, you can define a list of built-in API schema types that are applied to a prim instance of the IsA type). In this case, inherited types will inherit the built-ins from their base types.
### What do I need to change?
Based on this breaking change, there are two things that must be done in existing schemas:
- All applied API schemas must be changed to inherit from `</APISchemaBase>`
- The existing inheritance hierarchy must be converted to a set of built-ins (see examples below)
As an example, consider three applied API schemas Schema1API, Schema2API, and Schema3API, each currently inheriting from the one before as so:
```c++
class "Schema1API" (
inherits = </APISchemaBase>
customData = {
token apiSchemaType = "singleApply"
}
) {
}
class "Schema2API" (
inherits = </Schema1API>
customData = {
token apiSchemaType = "singleApply"
}
) {
}
class "Schema3API" (
inherits = </Schema2API>
customData = {
token apiSchemaType = "singleApply"
}
) {
}
```
To convert these, each would be modified to inherit APISchemaBase and to prepend the schema type they inherit as follows:
```c++
class "Schema1API" (
inherits = </APISchemaBase>
customData = {
token apiSchemaType = "singleApply"
}
) {
}
class "Schema2API" (
inherits = </APISchemaBase>
customData = {
token apiSchemaType = "singleApply"
}
prepend apiSchemas = ["Schema1API"]
) {
}
class "Schema3API" (
inherits = </APISchemaBase>
customData = {
token apiSchemaType = "singleApply"
}
prepend apiSchemas = ["Schema2API"]
) {
}
```
Since built-ins are recursive, we get the properties that we would expect from all three applied schemas when applying Schema3API to a prim, just as we would in the inheritance scenario.
### Accessing API Schema Attributes
Unfortunately, using the API schemas becomes a bit more burdensome than it is with inheritance. Prior to this change, a developer could modify any of the inherited attributes via the most-derived type:
```c++
Schema3API schema3API = Schema3API::Apply(prim);
```
```c++
int x = schema3API.GetSchema3Attr1().Get<int>();
double y = schema3API.GetSchema2Attr1().Get<double>();
```
This same approach does not work with built-ins, and so it is necessary at the current time to acquire the different API schemas in the built-ins set to set the attributes on each appropriately:
```c++
Schema3API schema3API = Schema3API::Apply(prim);
int x = schema3API.GetSchema3Attr1().Get<int>();
Schema2API schema2API = Schema2API(prim);
double y = schema2API.GetSchema2Attr1().Get<double>();
```
This requires (extensively) refactoring existing code, especially for schemas like physics that have API schemas that are heavily inheritance based. The expectation is that this will be addressed by USD to make this more developer friendly.
### Breaking Change: Schema Kind
From v21.02 onward, what used to be schema type is now referred to as schema kind. This change was made to disambiguate the schema type name (e.g. Schema1API) and what kind of schema it is (e.g. single-apply, multiple-apply, etc.). While the impact is small, it does require:
- Regeneration of the schema classes such that the GetSchemaKind method is generated over the GetSchemaType method (which will return a UsdSchemaKind not a UsdSchemaType)
- Code changes in any code that uses those methods of the schema (or associated methods of the UsdSchemaRegistry to reflect on schema types).
In practice, since the values of UsdSchemaKind are the same as the old UsdSchemaType enumeration, this means replacing any code that calls GetSchemaType with calls to GetSchemaKind and using UsdSchemaKind as the return value, on both schema types themselves and any code involving the UsdSchemaRegistry.
Also, if your plugInfo.json is missing the schemaKind field, it may silently fail to load.
For details on API breakage, see:
[Other Breaking Changes: Schemas: pugInfo.json: plugInfo.json now requires schemaKind field]
### Breaking Change: Retrieving Schema Type Names
From v21.02 onward, the GetSchemaPrimSpec method on UsdPrimDefinition has been removed. This method was used to get the “schema prim spec”, from which the schema type name of an e.g., C++ type could be retrieved. While there is no direct replacement on UsdPrimDefinition, similar functionality can be found in the UsdSchemaRegistry singleton object via the method GetSchemaTypeName:
```c++
/// Return the type name in the USD schema for prims or API schemas of
the
/// given registered \\p SchemaType.
template <class SchemaType>
static TfToken GetSchemaTypeName() {
return GetSchemaTypeName(SchemaType::_GetStaticTfType());
}
```
### New Feature: Auto-Applied API Schemas
An auto-applied API schema refers to a single-apply API schema that will be automatically attached to a set of prim instances of one or more defined schema types. This is a new feature that requires no migration of existing schema content and has two advantages:
- An existing schema set can be extended with additional attributes without having to modify the original schema. That is, if a schema Schema1 supplied a set of attributes, and a developer decides that there is an additional set of attributes that are directly relevant to prims that have Schema1 applied, then they can create a new schema Schema2API containing those new attributes and declare that it should be auto-applied to all prim instances of type Schema1 (in the case of typed schemas) or for which Schema1 is applied (in the case of API schemas), without modifying Schema1 itself. In the case of IsA schemas, the auto-apply rule would trigger on the specified schema being applied to a prim instance as well as any inherited type of that schema being applied.
- All prim instances that satisfy the auto apply to criteria automatically get the new schema applied without developers having to explicitly call Apply on each prim they want the schema to apply to.
The mechanism for defining this in a schema definition is via the apiSchemaAutoApplyTo attribute of the API schema type’s customData dictionary. This is an array of token strings defining the names of the schemas applied to a prim instance that trigger the auto-apply rule. Note this is an or set, not an and set (only one of the listed schemas need be applied to a prim instance for the auto-apply rule to trigger). For example, if a developer wanted to auto-apply a new schema type Schema1API to all prim instances of type UsdGeomMesh, their definition would look as follows:
```c++
class "Schema1API" {
inherits = </APISchemaBase>
customData = {
apiSchemaAutoApplyTo = ["UsdGeomMesh"]
}
}
```c++
token apiSchemaAutoApplyTo[] = ["UsdGeomMesh"];
}
}
```
Note that this functionality only applies to single-apply API schemas (as multiple-apply API schemas require an instance name to be specified on application).
The above technique is applied at schema generation time, which is sufficient for a broad number of use cases. USD also has an additional mechanism for supplying this information which applies later in the pipeline (i.e. after schema generation has occurred and is distributed). This is referred to as plugin defined auto-applied API schemas. This allows developers to specify additional auto-apply rules that may only affect a subset of schema consumers. While an uncommon use case, USD allows this type of auto-apply schema to be specified directly in the plugInfo.json file via the AutoApplyApiSchemas key contained in the Plugins.Info key. Representing the example above in the plugInfo.json file would look as follows:
```json
{
"Plugins": [
"Info": {
"AutoApplyAPISchemas": {
"Schema1API": {
"apiSchemaAutoApplyTo": [
"UsdGeomMesh"
]
}
}
}
]
}
```
## New Feature: Abstract Typed Schemas and the Schema Registry
Prior to v21.05, USD did not record abstract typed schemas as official USD type names in the schema registry. This effectively meant that developers could not refer to these abstract typed schemas in scenarios such as auto-apply of API schemas. This minor change makes abstract typed schemas first class citizens in the schema registry, and their type names can be used in auto-apply scenarios to capture a large number of prims who’s schemas are derived from the abstract schema. That is, consider the scenario below:
Figure 1: Abstract Typed Schemas with Auto-Apply
In this case, AppliedSchema1API will be auto-applied to all prims of type ConcreteSchema1, ConcreteSchema2, or ConcreteSchema3. Prior to this change, AppliedSchema1API would only have been allowed to specify one (or more) of the concrete schema types to auto-apply to.
## New Feature: Codeless Schemas
v21.08 introduced the concept of codeless schemas. These schemas have no generated code - only the type definition. This makes them easy to distribute, use, and iterate; providing a data contract without binary distribution issues (although codeless schemas are still discovered through the standard USD plug-in system). You may already be taking advantage of this feature - it was cherry picked into NVIDIA’s v20.08 USD source and made available to usdgenschema. Codeless schemas can be declared by adding the skipCodeGeneration attribute to the GLOBAL schema metadata. Note that this will cause all schemas defined in the schema.usda file to be codeless, so if you want both codeful and codeless schemas be sure to separate out their definitions into different schema.usda files.
As an example, let’s define a codeless schema for the following simple scenario:
Figure 2: Codeless Schema Example
```c++
over "GLOBAL" (
customData = {
bool skipCodeGeneration = true
}
) {
}
class "Schema1API" (
inherits = </APISchemaBase>
customData = {
token apiSchemaType = "singleApply"
}
)
{
int schema1:property1 = 5 ()
int schema1:property2 = 2 ()
}
```
The downside to codeless schemas is that you don’t get the nice wrappers for accessing properties on a prim associated with that schema that are available through the code generation. All property access must go through the generic API’s available on UsdPrim.
```c++
TfType schemaType = UsdSchemaRegistry::GetAPITypeFromSchemaTypeName("Schema1API");
bool hasApi = prim.HasAPI(schemaType);
if (hasApi)
{
int schema1APIProperty1Value = 0;
}
```c++
int schema1APIProperty2Value = 0;
prim.GetAttribute("schema1:property1").Get<int>(&schema1APIProperty1Value);
prim.GetAttribute("schema1:property2").Get<int>(&schema1APIProperty2Value);
assert(schema1APIProperty2Value == 2);
prim.GetAttribute("schema1:property2").Set<int>(schema1APIProperty1Value);
prim.GetAttribute("schema1:property2").Get<int>(&schemaAPIProperty2Value);
assert(schema1APIProperty2Value == 5);
}
```
## New Feature: Additional GLOBAL Schema Metadata to Define Use of Literal Identifier Names
In v22.05, USD added the ability for schema authors to specify that property names should be generated verbatim as written rather than the normal behavior of camel-casing them. This is a minor change, but helpful in scenarios where the schema.usda file is auto-generated by a tool rather than hand authored (e.g. usdgenschemafromsdr). To invoke this behavior, a new metadata key was added to the GLOBAL schema metadata:
```c++
over "GLOBAL" (
customData = {
string libraryName = "exampleLibrary"
string libraryPath = "."
bool useLiteralIdentifier = true
}
)
}
```
Adding this metadata informs usdgenschema to attempt to use the written property names verbatim. Note that normal rules still apply for identifiers, and usdgenschema will make the property name a valid identifier (via TfMakeValidIdentifier) if it is invalid, even in cases where useLiteralIdentifier is set in the GLOBAL metadata.
## New Feature: Defining Sparse Overrides From Built-Ins
In v22.08, USD introduced the ability for an API schema to perform a sparse override of a built-in’s property. In this scenario, an API schema may have an opinion on the default value of a property from one of its built-ins, without defining or owning the property itself. This is functionally similar to an over for the property, where the API schema defines a stronger opinion of the default value. Consider the following:
Figure 3: Sparse Overrides on Built-Ins
This new functionality can be taken advantage of by adding the apiSchemaOverride to the customData dictionary of the property.
```c++
class "Schema1API" (
) {
uniform int schema1:property = 5 (
)
}
class "Schema2API" (
prepend apiSchemas = ["Schema1API"]
) {
uniform int schema1:property = 2 (
customData = {
bool apiSchemaOverride = true
}
)
}
```
In this scenario, Schema2API has declared Schema1API a built-in and provided a sparse override of the schema1:property default value. Note that when doing this, the property must be declared with the exact same type and variability (e.g., uniform int in the above example), otherwise the override is ignored. Also note that this functionality is only available to API schemas and does not apply to overriding properties via IsA schema inheritance.
## Ar 2 (Asset Resolution Re-architecture)
### Introduction
## The Public Interface to Ar (Asset Resolution)
The public interface to Ar (Asset Resolution) has changed significantly, hence the version change from 1.0 to 2.0. While it is a significant change, the functionality is mostly the same but provides better hooks for cloud-based asset backends such as Nucleus. The parts of Ar that changed mostly relate to removed and renamed methods. In most circumstances, methods were removed since they really only applied to Pixar’s way of resolving assets. Other methods were renamed to more accurately convey their intent.
## Breaking Change: IsSearchPath() Removed
Search paths are no longer a part of the public interface of Ar 2.0. This was done for good reason as not all asset management systems support search paths. Internally, an implementation of Ar 2.0 can support search paths but there is no publicly available method such as ArGetResolver().IsSearchPath(). Originally, this method was made a part of the public Ar interface so Sdf could perform the “look here first” approach when resolving an SdfAssetPath that fit the criteria of a search path. If you are using ArGetResolver().IsSearchPath() it might be a good time to assess why you are using it before migrating your code as there is not an out-of-the-box solution. If ArGetResolver().IsSearchPath() is used in a lot of places we could add a utility function to mimic it’s behavior.
In order to migrate your code to check if an asset path is a search path it will need to pass the following checks:
1. It is not a URL prefixed with a scheme such as omniverse:// or https://
2. It is not an absolute file path i.e starting with / or \
3. It is not a file relative path:
- a. Does not start with ./ or ../
- b. Does not start with .\ or ..\
A C++ implementation would be:
// Add the C++ Implementation similar to what we are using in OmniUsdResolver_Ar1.cpp

API Breaking Changes: Ar.Resolver: IsSearchPath() Removed
## Breaking Change: IsRelativePath() Removed
As a part of the process to decouple assets from the filesystem, ArGetResolver().IsRelativePath() was also removed. While sometimes useful, it also made for a confusing API when paired with ArGetResolver().AnchorRelativePath(). It would make the caller think that you need to check if the asset path was relative before calling ArGetResolver().AnchorRelativePath() which was not always the case. If you find that you’re calling ArGetResolver().IsRelativePath() on asset paths before ArGetResolver().AnchorRelativePath() a better way to migrate your code would be to use a utility from Sdf:
auto stage = UsdStage::Open("omniverse://some/asset.usd");
const std::string assetPath = "./geom.usd";
// SdfComputeAssetPathRelativeToLayer works for both Ar 1.0 and Ar 2.0
// It will also handle all the edge cases dealing with things like anonymous layers,
// package relative paths, etc.
const std::string assetId = SdfComputeAssetPathRelativeToLayer(stage->GetRootLayer(), assetPath);
If you find that you do need to check if some string is relative, TfIsRelativePath() could be used. But it’s important to understand that TfIsRelativePath() will only work with filesystem paths. For example, TfIsRelativePath("omniverse://some/asset.usd") would return true. So only use TfIsRelativePath() if you’re sure it’s a filesystem path and not a URL.
For details on API breakage, see:
API Breaking Changes: Ar.Resolver: IsRelativePath() Removed
## Breaking Change: AnchorRelativePath() Renamed
ArGetResolver().AnchorRelativePath() was correctly renamed to ArGetResolver().CreateIdentifier(). The reason for this method being renamed is to clarify its intent which is to create an identifier for an incoming asset path. The incoming asset path may or may not be relative, but ArGetResolver().AnchorRelativePath() was always called to make sure the returned result was a valid identifier that could be consistently resolved.
```cpp
const std::string anchor = "omniverse://some/asset.usd";
const std::string assetPath = "./geom.usd";
##if !defined(AR_VERSION) || AR_VERSION < 2
// Ar 1.0
const std::string identifierAr1 = ArGetResolver().AnchorRelativePath(anchor, assetPath);
##else
// Ar 2.0 - The ArResolvedPath is required for the anchor to indicate to the ArResolver plugin
// implementing _CreateIdentifier that the anchor has already been resolved
const ArResolvedPath resolvedAnchor(anchor);
// Ar 2.0 - Note how the anchor and asset path order are switched
const std::string identifierAr2 = ArGetResolver().CreateIdentifier(assetPath, resolvedAnchor);
##endif
```
For details on API breakage, see:
API Breaking Changes: Ar.Resolver: AnchorRelativePath() to CreateIdentifier()
## Breaking Change: ComputeNormalizedPath() Removed
ArGetResolver().ComputeNormalizedPath() has been removed since in most cases it was a redundant call. Most ArResolver plugins would return the normalized form of an incoming asset path in ArGetResolver().AnchorRelativePath(). However, ArGetResolver().AnchorRelativePath() was vague as to the expected result. ArGetResolver().CreateIdentifier() clarifies that its returned result should be in its final normalized form.
For details on API breakage, see:
API Breaking Changes: Ar.Resolver: ComputeNormalizedPath() Removed
## Breaking Change: ComputeRepositoryPath() Removed
ArGetResolver().ComputeRepositoryPath() has been removed. A repository path, or repoPath, was a very Pixar specific way of identifying their assets within Perforce. For the majority of their assets they could compute the resolved path or local path to a repository path (identifier) in Perforce. In some ArResolver plugins a resolved path can not be computed to its repository path (identifier). For this reason, an ArResolver plugin would just return the incoming path as-is and adds to a confusing ArResolver interface.
In order to migrate your code the call to ArGetResolver().ComputeRepositoryPath() should just be removed. The OmniUsdResolver would just return the incoming path, nothing was actually computed since client-library does not support converting a resolved cached path to the URL it was resolved from.
For details on API breakage, see:
API Breaking Changes: Ar.Resolver: ComputeRepositoryPath() Removed
## Breaking Change: ComputeLocalPath() Removed
ComputeLocalPath() has been removed and replaced with more accurately named methods. In Ar 1.0, ComputeLocalPath() was called in SdfLayer::CreateNew to redirect a new layer to some local path on disk so it could still resolve. Ar 2.0 clarifies the interface by adding CreateIdentifierForNewAsset / ResolveForNewAsset methods
```c++
const std::string assetPath = "omniverse://some/new/asset.usd";
```
// Not completely necessary but makes sure the assetPath is absolute + normalized
```c++
const std::string identifier = ArGetResolver().CreateIdentifierForNewAsset(assetPath);
```
```c++
const ArResolvedPath resolvedPath = ArGetResolver().ResolveForNewAsset(identifier);
```
For details on API breakage, see:
API Breaking Changes: Ar.Resolver: ComputeLocalPath() Removed
## Breaking Change: Resolve() Signature Changed
Resolve() has changed the return type from std::string to ArResolvedPath. The ArResolvedPath type is just a shim around std::string to clarify the interface when an ArResolver plugin can expect to receive a resolved path. One of the confusing aspects of Ar 1.0 for an ArResolver plugin implementation was when you were receiving an unresolved asset path or a fully resolved path. This led to numerous subtle bugs when the plugin would assume a resolved path but would actually be receiving an asset path since everything was just typed from std::string.
The code required to support this change can be done in a few different ways and should be handled according to preference or coding style:
```c++
const std::string assetPath = "omniverse://some/asset.usd";
```
// In Ar 1.0
```c++
const std::string resolvedPath = ArGetResolver().Resolve(assetPath);
```
// In Ar 2.0
```c++
const ArResolvedPath resolvedPath = ArGetResolver().Resolve(assetPath);
```
// or to support Ar 1.0 + Ar 2.0
```c++
auto resolvedPath = ArGetResolver().Resolve(assetPath);
```
Another very important aspect of Resolve() is that USD no longer assumes that the returned result will point to a normal file path on disk! It is expected that Resolve() can return things such as URIs where any file system calls, i.e ArchOpenFile() and ArchGetFileLength(), will not work correctly and more than likely fail. If you are currently using any file system operations on a resolved asset path your code should be updated to use the ArAsset / ArWritableAsset abstractions so you can properly read / write data. See the sections on OpenAsset() / OpenAssetForWrite() for examples on reading / writing.
For details on API breakage, see:
API Breaking Changes: Ar.Resolver: Resolve() Signature Changed
## Breaking Change: ResolveWithAssetInfo() Removed
ResolveWithAssetInfo() has been removed and separated into two methods;
Resolve() and GetAssetInfo(). GetAssetInfo() accepts an asset path and an ArResolvedPath as input to accurately find all the information related to the asset. The ArResolvedPath can help with asset management systems that might need the identifier, along with the resolved result of that identifier to accurately return the ArAssetInfo with all the correct information.
```
```markdown
// In Ar 1.0
```
```markdown
// Note that assetPath would typically be the identifier returned from AnchorRelativePath()
```
```markdown
```cpp
const std::string assetPath = "omniverse://some/asset.usd";
ArAssetInfo assetInfo;
const std::string resolvedPath = ArGetResolver().ResolveWithAssetInfo(assetPath, &assetInfo);
```
```markdown
// In Ar 2.0
```
```markdown
```cpp
const std::string assetPath = "omniverse://some/asset.usd";
const ArResolvedPath resolvedPath = ArGetResolver().Resolve(assetPath);
ArAssetInfo assetInfo = ArGetResolver().GetAssetInfo(assetPath, resolvedPath);
```

```markdown
## Breaking Change: GetModificationTimestamp() Signature Changed
```
```markdown
GetModificationTimestamp() is another method that changes the return type to clarify what was expected to be returned for ArResolver plugin implementations. The return type for GetModificationTimestamp() changed from a VtValue to an ArTimestamp. The ArTimestamp is a more suitable type for external APIs to correctly sort and compare an asset’s modification timestamp due to its guaranteed comparison overload operators. These operators are important for a library such as Sdf to correctly reload layers, since the asset representing the SdfLayer needs to be sorted and compared based on the time the asset was last modified.
```
```markdown
// In Ar 1.0
```
```markdown
// Note that assetPath would typically be the identifier returned from AnchorRelativePath()
```
```markdown
```cpp
const std::string assetPath = "omniverse://some/asset.usd";
const std::string resolvedPath = ArGetResolver().Resolve(assetPath);
VtValue timestamp = ArGetResolver().GetModificationTimestamp(assetPath, resolvedPath);
```
```markdown
// In Ar 2.0
```
```markdown
```cpp
const std::string assetPath = "omniverse://some/asset.usd";
const ArResolvedPath resolvedPath = ArGetResolver().Resolve(assetPath);
ArTimestamp ts = ArGetResolver().GetModificationTimestamp(assetPath, resolvedPath);

## Breaking Change: OpenAsset() and ArAsset Signature Changes
```
```markdown
The change will mostly affect ArResolver plugin implementations, but is still a breaking change. OpenAsset() has changed its signature to ensure const-correctness. In Ar 1.0 this seemed like a bug, or oversight, where an ArResolver plugin would modify its own state when opening an asset for reading. This has been corrected in Ar 2.0 to guarantee that OpenAsset() is indeed const and will not modify its own state. The only required change here is for ArResolver plugin implementations to update their function signatures to mark it as const-qualified. This change also allows a const-qualified function to call ArGetResolver().OpenAsset() along with the virtual methods exposed by ArAsset such as GetSize(), GetBuffer(), Read(), etc.
```
```markdown
Additionally, the type of resolvedPath has changed from a std::string to an ArResolvedPath.
```
```markdown
Using OpenAsset() for reading assets has been supported since Ar 1.0. But now that ArGetResolver().Resolve() no longer assumes a file path on disk being returned, it’s very important to use OpenAsset() when data needs to be read from an asset path. Typical usage can look like the following:
```
```markdown
// In Ar 2.0
```
```cpp
const ArResolvedPath resolvedPath = ArGetResolver().Resolve(assetPath);
auto asset = ArGetResolver().OpenAsset(resolvedPath);
if (asset) {
// get the buffer to read data into
std::shared_ptr<const char> buffer = asset->GetBuffer();
if (!buffer) {
TF_RUNTIME_ERROR("Failed to GetBuffer()");
return;
}
size_t bytesRead = asset->Read(buffer.get(), asset->GetSize(), 0);
if (bytesRead == 0) {
TF_RUNTIME_ERROR("Failed to read asset");
return;
}
// buffer should now contain bytesRead chars read from resolvedPath
}
```
For details on API breakage, see:
API Breaking Changes: Ar.Resolver: OpenAsset() / ArAsset Signature Changes
## New Feature: OpenAssetForWrite() and ArWritableAsset
One of the big features of Ar 2.0 is the ability to write data directly to the underlying asset management system in an abstracted, and extendable, way. ArGetResolver().OpenAssetForWrite() is a hook in an ArResolver plugin implementation to assist and control how something is written to the asset management system. This new feature allows for things like streaming writes without the need to directly link against custom libraries like client-library. This greatly simplifies the process of getting new assets into asset management systems such as Nucleus, and is natively supported across all of USD through facilities like SdfFileFormat plugins. A very naive implementation could look something like the following:
```cpp
const std::string assetPath = "omniverse://some/asset.usd";
// if writing to an existing asset
const ArResolvedPath resolvedPath = ArGetResolver().Resolve(assetPath);
// or if writing to a new asset
const ArResolvedPath resolvedPath = ArGetResolver().ResolveForNewAsset(assetPath);
// create a buffer that contains the data we want to write
const size_t bufferSize = 4096;
std::unique_ptr<char[]> buffer(new char[bufferSize]);
// put some data into the buffer
const std::string data = "some asset data";
memcpy(buffer.get(), data.c_str(), data.length());
// open the asset for writing
auto writableAsset = ArGetResolver().OpenAssetForWrite(resolvedPath, ArResolver::WriteMode::Replace);
if (writableAsset) {
const size_t bytesWritten = writableAsset->Write(buffer.get(), data.length(), 0);
if (bytesWritten == 0) {
TF_RUNTIME_ERROR("Failed to write asset");
return;
}
// close out the asset to indicate that all data has been written
asset->Close();
}
```
## New Feature: ArAsset Detached Assets
Detached assets are a new way to completely separate an ArAsset from the underlying asset management system. In some asset management systems its possible for assets to continuously receive updates. Updates like this can cause instability if the asset is in the process of being read into memory and the asset changes from underneath it. GetDetachedAsset() on ArAsset is a place for an ArResolver plugin to perform any necessary steps to ensure that the returned ArAsset will be consistent for reads throughout its lifetime.

const std::string assetPath = "omniverse://some/new/asset.usd";
ArResolver& resolver = ArGetResolver();
auto resolvedPath = resolver.Resolve(assetPath);
auto myAsset = resolver.OpenAsset(resolvedPath);
```
Python Example Before:
NOTE: in most contexts, you will feed the resolves of Resolve() to a function that now expects an Ar.ResolvedPath object, such as ArResolver.CreateIdentifier, so NO CHANGES are needed
However, if you formerly attempted to use the resolved path as a string, changes will be required:
```python
from pxr import Ar
assetPath = "omniverse://some/new/asset.usd"
resolvedPath = Ar.GetResolver().Resolve(assetPath)
resolvedPath.split("/")
```
Python Example After (all versions):
```python
from pxr import Ar
assetPath = "omniverse://some/new/asset.usd"
resolvedPath = str(Ar.GetResolver().Resolve(assetPath))
resolvedPath.split("/")
```

## Usd SchemaRegistry
### Usd SchemaRegistry
### SchemaType to SchemaKind
For a detailed explanation, see: Breaking Change: Schema Kind
| | | |
|---|---|---|
| | Reference Commits: | * UsdSchemaRegistry can now query about schema kind from the schemaKind plugInfo metadata that is generated by usdGenSchema for schema types. This is directly exposed through the new GetSchemaKind functions added to UsdSchemaRegistry.<br/>* Intermediary release work for the transition to schemaKind nomenclature from schemaType.<br/>* Removing the deprecated GetSchemaType and static schemaType from UsdSchemaBase.<br/>* |
- Updating usdGenSchema to no longer generate the deprecated schemaType
- Removing the backward compatibility in UsdSchemaRegistry for schemas that have not been regenerated to include schemaKind in their pluginInfo metadata.
### C++/Python Find Regex:
SchemaType
### C++/Python Replace Regex:
SchemaKind
### Python Example Before:
```python

## Property Names of MultipleApply Schemas now namespaced in schema spec
ie, the schema spec for CollectionAPI’s “includes” relationship was formerly just includes
Now, it includes a template for the instance name, and is:
```
```markdown
collection:__INSTANCE_NAME__:includes
```
Use `Usd.SchemaRegistry.GetMultipleApplyNameTemplateBaseName(propertySpec.name)` to return just the “includes” portion, as before.
Functions for dealing with the new templated names can be found in [UsdSchemaRegistry]:
- [GetMultipleApplyNameTemplateBaseName]
- [IsMultipleApplyNameTemplate]
- [MakeMultipleApplyNameInstance]
- [MakeMultipleApplyNameTemplate]
```
```markdown

## UsdLuxLight.ComputeBaseEmission() removed
This function existed “solely as a reference example implementation of how to interpret [UsdLuxLight’s] parameters.” It has been removed, and there is no replacement. If you were making use of it, you will have to add your own implementation - this function would duplicate the old behavior:
```c++
GfVec3f ComputeBaseEmission(const UsdLuxLightAPI& light)
{
GfVec3f e(1.0);
float intensity = 1.0;
light.GetIntensityAttr().Get(&intensity);
e *= intensity;
float exposure = 0.0;
light.GetExposureAttr().Get(&exposure);
e *= exp2(exposure);
GfVec3f color(1.0);
light.GetColorAttr().Get(&color);
e = GfCompMult(e, color);
bool enableColorTemp = false;
light.GetEnableColorTemperatureAttr().Get(&enableColorTemp);
if (enableColorTemp) {
float colorTemp = 6500;
if (light.GetColorTemperatureAttr().Get(&colorTemp)) {
e = GfCompMult(e, UsdLuxBlackbodyTemperatureAsRgb(colorTemp));
}
}
return e;
}

## Material Bindings Require UsdShadeMaterialBindingAPI to be Applied
- All code which authors material bindings should Apply() UsdShadeMaterialBindingAPI to the prim upon which the binding is to be authored
- Current default is to post warnings at runtime, but still apply material bindings if is not applied
- May set USD_SHADE_MATERIAL_BINDING_API_CHECK env var to change behavior:
- allowMissingAPI
- silence warnings and apply materials even if MaterialBindingAPI not applied
- warnOnMissingAPI
- current default
- print warnings, but still apply materials even if MaterialBindingAPI not applied
- strict
- future default
- only apply material bindings if MaterialBindingAPI applied
- Assets can be repaired via the Asset Validator extension, see UsdMaterialBindingApi.
### Table
| | Reference Commits: |
|---|--------------------|
| | BindingAtPrim should return early if the prim doesn’t have a MaterialBindingAPI Applied. |
| | Change USD_SHADE_MATERIAL_BINDING_API_CHECK to “warnOnMissingAPI”. |
| | Runtime Warning Strings: |
| | * Found material bindings on prim at path (%s) but MaterialBindingAPI is not applied on the prim |
## UsdSkel
### UsdSkel Cache
#### Populate/ComputeSkelBinding/ComputeSkelBindings now require a predicate parameter
To maintain the same behavior, pass UsdPrimDefaultPredicate as the predicate; if you wish to allow instancing of skeletons, use UsdTraverseInstanceProxies instead

### Hdx
#### Hdx TaskController
##### Added HdxTaskController SetPresentationOutput
It seems that when SetPresentationOutput was originally added in 22.05, calling it from UsdImagingGLEngine / omni.hydra.pxr’s SimpleUsdGLEngine.cpp may have been required, but in 22.08 the functionality was moved to HgiInteropOpenGL
Reference Commits:
* Adding SetPresentationOutput to HdxPresentTask, HdxTaskController.
* Adding UsdImagingGLEngine::SetPresentationOutput.
* [UsdImagingGL] Removed most direct use of GL from UsdImagingGL… Also, we no longer explicitly set the current draw framebuffer binding as the presentation output in the task controller since the fallback behavior in HgiInteropOpenGL is to present to the current draw framebuffer.

## Structural Pieces
### Node Type Version Number
Every .ogn file is required to supply a node version number using the `"version": N` keyword. With an AutoNode definition there is no version number, partly due to the fact that it is less useful for this type of node type definition. In particular for an AutoNode definition:
- the node types are not serialized so the version number would not persist
- there is no mechanism for updating a node from an earlier version number, if one was requested
### Node Types Not Implemented In Python
It may seem obvious but is still worth mentioning that all AutoNode definitions create node type definitions for node types that are implemented in Python. The decorator is in Python and the function it decorates is in Python so it is natural that the node type stays in Python. This does not preclude using Python libraries such as Warp to move the Python code to other languages such as Cuda or C++, however that is something the user would have to do.
### Generation Of Documentation, Tests, And USD Example Files
One of the side benefits of having a definition in a .ogn file is that the code generator can take that definition and create other useful outputs from that definition. In particular it is typical to have node type documentation automatically generated, which is a restructuredText file containing a nicely formatted page with the node type metadata and all of the attribute information.
Similarly a set of standardized tests can be created that test basic node operation, including reading the node type definition from a .usda file to confirm that things like default values behave correctly. With an AutoNode definition this is less useful to have since the whole point is rapid development and extra elements such as documentation and tests are more suited to more permanent node type definitions, where they might belong to an extension or be indexed in a library for easy discovery.
### Attribute Documentation
While the node type documentation can be pulled from the decorated function’s docstring there is no similar location to attach such information to the input or output attributes. As a result the attributes will be undocumented and
when users are interacting with them they will not have that information available.
An easy workaround to this shortcoming is to embed the attribute information in the function docstring, much in the same way as you might see in regular coding documentation styles. For example, here’s a function that uses the Google developer documentation style.
```python
import numpy as np
import omni.graph.core as og
import omni.graph.core.types as ot
@og.create_node_type
def autonode_documented(a: ot.point3d, b: ot.point3d) -> ot.vector3d:
"""This node type is an example of one where the intent of the attribute values is not easily apparent
from their names. For that reason the documentation for what they are is embedded here in the function
docstring. The function itself is calculating the normalized vector between two points. The attributes
are documented explicitly here to provide more information to the user.
Args:
a: Point considered to be the origin of the vector
b: Point considered to be the ending point of the vector
Returns:
out_0: Normalized vector from point a to point b
"""
return (b - a) / np.linalg.norm(b - a)
```
### Attribute Metadata
Like node types, attributes also have useful metadata such as `ui_name` that is not possible to provide directly. Some metadata values will take on useful defaults while others, such as `minimum value`, will just be absent. It is an implementation detail about attributes that while their structure is specified in the arguments of a decorated AutoNode function, or in the .ogn file, the actual Attribute object is copied from that structure and contains its own unique metadata.
For that reason, you can work around the missing metadata if you really need to by accessing the attributes directly and modifying the metadata after a node of the new type has been created. Here is a brute force method to get all nodes of the type `omni.graph.normalize` and set the output attribute’s UI name to “Normalized Vector”.
```python
import omni.graph.core as og
import omni.graph.tools.ogn as ogn
for graph in og.get_all_graphs():
for node in graph.get_nodes():
if node.get_type_name() != "omni.graph.normalize":
continue
node.get_attribute("outputs:out_0").set_metadata(ogn.MetadataKeys.UI_NAME, "Normalized Vector")
```
### Custom Naming Of Attribute Outputs
As you have probably noted from the examples, the output attributes all have numbered names such as `out_0`, `out_1`, etc. whereas node types defined through a .ogn file have explicit names. The name of an attribute is intentionally immutable so there is no API that will let you assign a new name to the output as there is for setting the UI name through the metadata. Short of doing something heroic, like setting up an indirection table to remap all of your attribute names from the ones you want to use to the numbered names, there is no way to use a more meaningful name for the output attributes.
### Attribute Memory Types
In a .ogn file you can specify an attribute’s memory affinity using the `memoryType` keyword, either at the node type level or on a per-attribute basis. What this does is to cause the generated code to request the attribute’s value on the appropriate device without need for user intervention. With the AutoNode wrapping around the actual data retrieval there is no access to allow specification for attribute values to be retrieved from anywhere other than the CPU.
Outside of a compute method you are still free to request that the data be retrieved from any arbitrary device but inside the decorated function you are restricted to CPU access only.
### Extended Attribute Types
While you can specify extended attribute types as part of an AutoNode decorated function argument list you will be unable to resolve the attribute types to a concrete type at runtime. Therefore they won’t be very useful types as they will never contain real values.
Instead, stick with concrete data types. AutoNode functions are meant to be simple anyway so overloading a function to handle many different types of data is against its purpose. Favor a quick function that adds two integers together over a more complex node type definition that reads the underlying types and dispatches the correct add code to the resolved data type values.
## Defining Methods Other Than compute()
As you might have guessed from some of the above limitations, there are some features on the node type that rely on access to other functions that might be overridden in a node type implementation. The more common ones of these are `initialize()`, `initialize_type()`, and `release()`.
As `AutoNode` functions are not full fledged class objects it is only possible for them to override a single function, which will always be the `compute()`. (In fact it actually wraps the function in some helper code that sets up and tears down the data for the function call.)
Some features of these extra functions can be handled in other ways, such as the use of the `metadata` keyword in the decorator arguments, or the brute force addition of attribute metadata seen above. For anything more complex you are better off creating a full node type implementation with a .ogn/.py file pair.
## Accessing Node And Context In compute()
As the decorated function assumes every argument passed in to it is an input attribute there is no room for accessing other types of information. In particular, in a normal `compute()` override the function will have access to both the node and the context of the current evaluation. (In generated node types the information is further wrapped in a more feature-rich database class.)
Although the node and context are available in the wrapper function they cannot be accessed directly as they have not been passed in to the decorated function. However you can make use of the Python `inspect` module and some implementation information that the arguments will always be named `node` and `context` to look up that information.
```python
import inspect
import omni.graph.core as og
import omni.graph.core.types as ot
@og.create_node_type
def autonode_access_node() -> ot.string:
"""This node type is an example of how to use the inspect module to access the node that is evaluating
this function as its compute. (The context could be accessed the same way.) The node type takes no
inputs and returns as output the full path to the node being evaluated. It relies on some implementation
details not changing but for the most part should be reliable."""
frame = inspect.currentframe().f_back
return frame.f_locals.get("node").get_prim_path()
```
## Emitting Errors And Warnings In compute()
The database generated when using a .ogn file has some useful utilities, one of which is the ability to log an error or a warning with the node so that the UI can report on execution failures. As the `AutoNode` function has no database this convenience cannot be used.
Fortunately the logging capability is in the node’s API so all you need to do to manually log messages is to access the node using the inspect module as above and call the log function with the appropriate logging level set. Here is an example that uses both warnings and errors to provide status information to the UI.
```python
import inspect
import omni.graph.core as og
import omni.graph.core.types as ot
@og.create_node_type
def autonode_logging(numerator: ot.double, denominator: ot.double) -> ot.double:
"""This node type is an example of how to use the inspect module to access the node that is evaluating
this function in order to log error and warning messages. The function divides the first number by the
second number, providing an error when the denominator is zero and a warning when both the numerator and
denominators are zero, otherwise returning the first number divided by the second."""
if denominator != 0.0:
return numerator / denominator
frame = inspect.currentframe().f_back
node = frame.f_locals.get("node")
if numerator == 0.0:
node.log_compute_message(og.Severity.WARNING, "Indeterminate result from dividing 0 by 0")
else:
node.log_compute_message(og.Severity.WARNING, f"Infinite result from dividing {numerator} by 0")
```
# While you can also log an error by setting severity to og.Severity.ERROR, it is better to use an
# exception so that the compute function will fail and no further computation will take place.
# if numerator == 0.0:
# raise og.OmniGraphError("Indeterminate result from dividing 0 by 0")
return 0.0
## Creating New Output Bundles In compute()
Normally when you want to output a bundle you would construct one using the generated database’s convenience function
for doing that. You can also implement this yourself, however you need to emulate that same convenience function, which
requires access to both the node and the context via the inspect module.
```python
import inspect
import omni.graph.core as og
import omni.graph.core.types as ot
@og.create_node_type
def autonode_output_bundles() -> ot.bundle:
"""This node type is an example of how to use the inspect module to access the node and context of evaluation
in order to construct a bundle for use as an output value.
"""
frame = inspect.currentframe().f_back
node = frame.f_locals.get("node")
context = frame.f_locals.get("context")
new_bundle = og.BundleContents(context, node, "outputs_out_0", read_only=False, gpu_by_default=False)
new_bundle.add_attributes([og.Type(og.BaseDataType.INT)], ["fizzbin"])
return new_bundle
```
## Accessing Per-Node Data
As with the message logging, the generated database provides access to internal state data that is associated with each
individual node. This data is controlled by the user. Again since there is no database with an
AutoNode node type
this feature is not available, though with the help of the inspect module it can be implemented locally with not
too much effort:
```python
import inspect
import omni.graph.core as og
import omni.graph.core.types as ot
unique_id = 57
per_node_data = {}
@og.create_node_type
def autonode_per_node_data(increment: ot.int) -> ot.int:
"""This node type is an example of how to use the inspect module to access the node that is evaluating
this function in order to create per-node personal data. This particular example provides a monotonic ID
that increases for each node created by maintaining a local per-node dictionary that uses the node's
internal ID as a key.
"""
nonlocal unique_id
nonlocal per_node_data
frame = inspect.currentframe().f_back
node_id = frame.f_locals.get("node").node_id()
if node_id not in per_node_data:
per_node_data[node_id] = unique_id
unique_id += increment
return per_node_data[node_id]
```
## Saving The Node Type Definition
As the node type definition is created at runtime there is no artifact to be referenced to find that node type
definition in another session. Although the node type definition may have a particular extension associated with it
there is no guarantee that merely loading that extension will recreate that node type definition. Indeed it may be
impossible if some of the parameters used in its creation are session-dependent, such as date of creation.
To warn the user that they might be saving node types that cannot be retrieved a warning will be issued when a file is
saved that contains an instantiated node of any
AutoNode type. And in future when required extensions are saved
with the USD files any extension called out in an
AutoNode definition will be included.
## Concrete Extension Dependencies
Further to the above, it is quite possible that an
AutoNode may have dependencies on specific extensions. These dependencies will need to be managed to ensure that the
AutoNode can function correctly in different environments.
# AutoNode
A decorated function could have dependencies on any arbitrary extension that is currently loaded. For this reason, it's also possible that another user running the exact same decorated function may not get a functioning node type if they do not have the requisite extensions enabled.
Again, another reason why nodes with these types will not be silently saved as they could cause the graph to become non-functional when read into another session. |
Model-View-Delegate%20Pattern.md | # Model-View-Delegate Pattern
Omni.ui graph widget strictly follows the model-view-delegate pattern. The model is independent of the UI, so that you can have different delegates (looks) for the same model or different models use the same delegate.
We define `GraphModel` as the base class for graph widgets’ model, which is the central component of the graph widget and manages the graph data. The node and port themselves could be any type to suit your application.
`AbstractGraphNodeDelegate` is the base class for graph nodes’ delegate, which defines the look of the nodes. Each node could have several different expansion states: open, closed, minimized. Moreover, different types of nodes could have different delegates. We use `GraphNodeDelegateRouter` as a condition “map” to assign the delegates based on the condition of the nodes.
`GraphView`, defined in omni.kit.widget.graph, is coordinating the above model and delegate, providing the workflow and managing model and delegates.
Everything needed for the Omni.ui graph is done in Python. There is no C++ required. But the core is in C++ so still quite fast even for large graphs. |

The PrimCache Population module implements core scenegraph composition semantics - behaviors informally referred to as Layering & Referencing.
## PhysicsSchemaTools
Omniverse-specific: The Physics Schema Tools provides tools for the representation of physics properties and behaviors in a 3D scene, such as gravity, collisions, and rigid body dynamics.
## Plug
Provides a plug-in framework implementation. Define interfaces, discover, register, and apply plug-in modules to nodes.
## Sdf
The Sdf (Scene Description Foundation) provides foundations for serializing scene description and primitive abstractions for interacting.
## Sdr
The Sdr library provides a runtime-extensible taxonomy known as “kinds”. Useful for classifying scenegraph objects.

names.md | # Choosing Names
## Brand (Company/Person) Name: `my_name`
For example, for extensions or applications created by the Omniverse team `my_name` is `omni` like `omni.kit.window.extensions` for an extension or `omni.create` for an application.
We recommend that you use a clear and unique name for that and use it for all your apps and extensions.
### A few rules to follow when selecting it
1. Don’t use a generic name like `bob` or `cloud`
2. Don’t use `omni` as this is reserved for NVIDIA Applications or Extensions
3. Be consistent. Select one and stick to it
## App Name: `my_app`
When building applications you might want to namespace the extension within the app name they belong to like `omni.code` for an application where we have then `omni.code.setup` etc.
For that name you have more freedom as it is already in your `my_name` namespace so it should not clash with someone else’s “editor” or “viewer”.
It would then be acceptable to have `my_name.editor` or `my_name.player` but you still want to think about giving your application some good identity.
## Shared Extensions
Aside from the extension you build specifically for your App there might be some that you want to make more generic and reuse across applications.
That is very possible and even recommended. That is how Omniverse Shared Extensions are built. We have them in namespaces like `omni.kit.widget.`
# 代码块示例
## 命名空间示例
可以使用以下命名空间：
```
omni.kit.window.
```
或者
```
<my_name>.widget.
```
通过这种方式，当其他开发者或用户想要开始使用你的扩展时，可以清楚地知道这些扩展来自于你（`<my_name>`）。你可以在 `extension.toml` 文件的仓库字段中说明它们的来源。 |

<p>
Interface for discovery plugins.
</p>
<p>
Discovery plugins, like the name implies, find nodes. Where the plugin
searches is up to the plugin that implements this interface. Examples
of discovery plugins could include plugins that look for nodes on the
filesystem, another that finds nodes in a cloud service, and another
that searches a local database. Multiple discovery plugins that search
the filesystem in specific locations/ways could also be created. All
discovery plugins are executed as soon as the registry is
instantiated.
</p>
<p>
These plugins simply report back to the registry what nodes they found
in a generic way. The registry doesn’t know much about the innards of
the nodes yet, just that the nodes exist. Understanding the nodes is
the responsibility of another set of plugins defined by the
<code>
NdrParserPlugin
</code>
interface.
</p>
<p>
Discovery plugins report back to the registry via
<code>
NdrNodeDiscoveryResult
</code>
s. These are small, lightweight classes
that contain the information for a single node that was found during
discovery. The discovery result only includes node information that
can be gleaned pre-parse, so the data is fairly limited; to see
exactly what’s included, and what is expected to be populated, see the
documentation for
<code>
NdrNodeDiscoveryResult
</code>
.

<section id="how-to-create-a-discovery-plugin">
<h2>
How to Create a Discovery Plugin
</h2>
<p>
There are three steps to creating a discovery plugin:
</p>
<blockquote>
<div>
<ul>
<li>
<p>
Implement the discovery plugin interface,
<code>
NdrDiscoveryPlugin
</code>
</p>
</li>
<li>
<p>
Register your new plugin with the registry. The registration
macro must be called in your plugin’s implementation file:
</p>
</li>
</ul>
</div>
</blockquote>
<div>
<pre>
NDR_REGISTER_DISCOVERY_PLUGIN(YOUR_DISCOVERY_PLUGIN_CLASS_NAME)
This macro is available in discoveryPlugin.h.
- In the same folder as your plugin, create a ``plugInfo.json``
file. This file must be formatted like so, substituting
``YOUR_LIBRARY_NAME`` , ``YOUR_CLASS_NAME`` , and
``YOUR_DISPLAY_NAME`` :
</pre>
</div>
<div>
<pre>
{
"Plugins": [{
"Type": "module",
"Name": "YOUR_LIBRARY_NAME",
"Root": "@PLUG_INFO_ROOT@",
"LibraryPath": "@PLUG_INFO_LIBRARY_PATH@",
"ResourcePath": "@PLUG_INFO_RESOURCE_PATH@",
"Info": {
"Types": {
"YOUR_CLASS_NAME" : {
"bases": ["NdrDiscoveryPlugin"],
"displayName": "YOUR_DISPLAY_NAME"
}
}
}
}]
}
</pre>
</div>
<p>
The NDR ships with one discovery plugin, the
<code>
_NdrFilesystemDiscoveryPlugin
</code>
. Take a look at NDR’s plugInfo.json
file for example values for
<code>
YOUR_LIBRARY_NAME
</code>
,
<code>
YOUR_CLASS_NAME
</code>
, and
<code>
YOUR_DISPLAY_NAME
</code>
. If multiple
discovery plugins exist in the same folder, you can continue adding
additional plugins under the
<code>
Types
</code>
key in the JSON. More detailed
information about the plugInfo.json format can be found in the
documentation for the
<code>
plug
</code>
module (in pxr/base).

The context is the context that the node declares itself as having (or, if a particular node does not declare a context, it will be assigned a default context by the parser).
As a concrete example from the `Sdr` module, a shader with a specific source type may perform different duties vs. another shader with the same source type. For example, one shader with a source type of `SdrArgsParser::SourceType` may declare itself as having a context of 'pattern', while another shader of the same source type may say it is used for lighting, and thus has a context of 'light'.
### GetFamily
- **Description:** Gets the name of the family that the node belongs to. An empty token will be returned if the node does not belong to a family.
- **Returns:** str
### GetIdentifier
- **Description:** Return the identifier of the node.
- **Returns:** NdrIdentifier
### GetInfoString
- **Description:** Gets a string with basic information about this node. Helpful for things like adding this node to a log.
- **Returns:** str
### GetInput
- **Description:** Get an input property by name. `nullptr` is returned if an input with the given name does not exist.
- **Parameters:**
- **inputName** (str)
- **Returns:** Property
### GetInputNames
- **Description:** Get an ordered list of all the input names on this node.
- **Returns:** NdrTokenVec
### GetMetadata
- **Description:** All metadata that came from the parse process. Specialized nodes may isolate values in the metadata (with possible manipulations and/or additional parsing) and expose those values in their API.
- **Returns:** NdrTokenMap
### GetName
- **Description:** Gets the name of the node.
- **Returns:** str
### GetOutput
- **Description:** Get an output property by name. `nullptr` is returned if an output with the given name does not exist.
- **Parameters:**
- **outputName** (str)
- **Returns:** Property
### Parameters
- **outputName** (`str`) –
### GetOutputNames
- **Function**: `GetOutputNames()`
- **Returns**: `NdrTokenVec`
- **Description**: Get an ordered list of all the output names on this node.
### GetResolvedDefinitionURI
- **Function**: `GetResolvedDefinitionURI()`
- **Returns**: `str`
- **Description**: Gets the URI to the resource that provided this node’s definition.
- Could be a path to a file, or some other resource identifier. This URI should be fully resolved.
### GetResolvedImplementationURI
- **Function**: `GetResolvedImplementationURI()`
- **Returns**: `str`
- **Description**: Gets the URI to the resource that provides this node’s implementation.
- Could be a path to a file, or some other resource identifier. This URI should be fully resolved.
### GetSourceCode
- **Function**: `GetSourceCode()`
- **Returns**: `str`
- **Description**: Returns the source code for this node.
- This will be empty for most nodes. It will be non-empty only for the nodes that are constructed using NdrRegistry::GetNodeFromSourceCode(), in which case, the source code has not been parsed (or even compiled) yet.
- An unparsed node with non-empty source-code but no properties is considered to be invalid. Once the node is parsed and the relevant properties and metadata are extracted from the source code, the node becomes valid.
### GetSourceType
- **Function**: `GetSourceType()`
- **Returns**: `str`
- **Description**: Gets the type of source that this node originated from.
- Note that this is distinct from `GetContext()`, which is the type that the node declares itself as having.
- As a concrete example from the `Sdr` module, several shader parsers exist and operate on different types of shaders. In this scenario, each distinct type of shader (OSL, Args, etc) is considered a different source, even though they are all shaders. In addition, the shaders under each source type may declare themselves as having a specific context (shaders can serve different roles). See `GetContext()` for more information on this.
### GetVersion
- **Function**: `GetVersion()`
- **Returns**: `Version`
- **Description**: Return the version of the node.
### IsValid
- **Function**: `IsValid()`
- **Returns**: `bool`
- **Description**: Whether or not this node is valid.
- A node that is valid indicates that the parser plugin was able to successfully parse the contents of this node.
Note that if a node is not valid, some data like its name, URI, source code etc. could still be available (data that was obtained during the discovery process). However, other data that must be gathered from the parsing process will NOT be available (eg, inputs and outputs).

class pxr.Ndr.Property
Represents a property (input or output) that is part of a `NdrNode` instance.
A property must have a name and type, but may also specify a host of additional metadata. Instances can also be queried to determine if another `NdrProperty` instance can be connected to it.
In almost all cases, this class will not be used directly. More specialized properties can be created that derive from `NdrProperty`; those specialized properties can add their own domain-specific data and methods.
**Methods:**
- **CanConnectTo(other)**
Determines if this property can be connected to the specified property.
- **GetArraySize()**
Gets this property's array size.
- **GetDefaultValue()**
Gets this property's default value associated with the type of the property.
- **GetInfoString()**
Gets a string with basic information about this property.
- **GetMetadata()**
All of the metadata that came from the parse process.
- **GetName()**
Gets the name of the property.
- **GetType()**
Gets the type of the property.
- **GetTypeAsSdfType()**
Converts the property's type from `GetType()` into a `SdfValueTypeName`.
- **IsArray()**
Whether this property's type is an array type.
- **IsConnectable()**
Whether this property can be connected to other properties.
- **IsDynamicArray()**
Whether this property's array type is dynamically-sized.
- **IsOutput()**
Whether this property is an output.
### CanConnectTo
- **Parameters**:
- `other` (Property) –
- **Description**:
Determines if this property can be connected to the specified property.
### GetArraySize
- **Description**:
Gets this property’s array size.
If this property is a fixed-size array type, the array size is returned. In the case of a dynamically-sized array, this method returns the array size that the parser reports, and should not be relied upon to be accurate. A parser may report -1 for the array size, for example, to indicate a dynamically-sized array. For types that are not a fixed-size array or dynamic array, this returns 0.
### GetDefaultValue
- **Description**:
Gets this property’s default value associated with the type of the property.
### GetInfoString
- **Description**:
Gets a string with basic information about this property. Helpful for things like adding this property to a log.
### GetMetadata
- **Description**:
All of the metadata that came from the parse process.
### GetName
- **Description**:
Gets the name of the property.
### GetType
- **Description**:
Gets the type of the property.
### GetTypeAsSdfType
- **Description**:
Converts the property’s type from `GetType()` into a `SdfValueTypeName`.
type, and an inexact mapping. In the first scenario, the first element
in the pair will be the cleanly-mapped Sdf type, and the second
element, a TfToken, will be empty. In the second scenario, the Sdf
type will be set to
```code
Token
```
to indicate an unclean mapping, and the
second element will be set to the original type returned by
```code
GetType()
```

The registry provides access to node information.”Discovery
Plugins”are responsible for finding the nodes that should be included
in the registry.
</p>
<p>
Discovery plugins are found through the plugin system. If additional
discovery plugins need to be specified, a client can pass them to
```code
SetExtraDiscoveryPlugins()
```
.
</p>
<p>
When the registry is first told about the discovery plugins, the
plugins will be asked to discover nodes. These plugins will generate
```code
NdrNodeDiscoveryResult
```
instances, which only contain basic
metadata. Once the client asks for information that would require the
node’s contents to be parsed (eg, what its inputs and outputs are),
the registry will begin the parsing process on an as-needed basis. See
```code
NdrNodeDiscoveryResult
```
for the information that can be retrieved
without triggering a parse.

Some methods in this module may allow for a”family”to be provided. A
family is simply a generic grouping which is optional.

## GetAllNodeSourceTypes
Get a sorted list of all node source types that may be present on the nodes in the registry.
Source types originate from the discovery process, but there is no guarantee that the discovered source types will also have a registered parser plugin. The actual supported source types here depend on the parsers that are available. Also note that some parser plugins may not advertise a source type.
See the documentation for `NdrParserPlugin` and `NdrNode::GetSourceType()` for more information.
## GetNodeByIdentifier
Get the node with the specified `identifier`, and an optional `sourceTypePriority` list specifying the set of node SOURCE types (see `NdrNode::GetSourceType()`) that should be searched.
If no sourceTypePriority is specified, the first encountered node with the specified identifier will be returned (first is arbitrary) if found.
If a sourceTypePriority list is specified, then this will iterate through each source type and try to find a node matching by identifier. This is equivalent to calling NdrRegistry::GetNodeByIdentifierAndType for each source type until a node is found.
Nodes of the same identifier but different source type can exist in the registry. If a node ‘Foo’ with source types ‘abc’ and ‘xyz’ exist in the registry, and you want to make sure the ‘abc’ version is fetched before the ‘xyz’ version, the priority list would be specified as [‘abc’, ‘xyz’]. If the ‘abc’ version did not exist in the registry, then the ‘xyz’ version would be returned.
Returns `nullptr` if a node matching the arguments can’t be found.
### Parameters
- **identifier** (NdrIdentifier) –
- **sourceTypePriority** (NdrTokenVec) –
## GetNodeByIdentifierAndType
Get the node with the specified `identifier` and `sourceType`.
If there is no matching node for the sourceType, nullptr is returned.
### Parameters
- **identifier** (NdrIdentifier) –
- **sourceType** (str) –
## GetNodeByName
Get the node with the specified `name`, `sourceTypePriority`, and `filter`.
### GetNodeByName
Get the node with the specified name.
An optional priority list specifies the set of node SOURCE types (NdrNode::GetSourceType()) that should be searched and in what order. Optionally, a filter can be specified to consider just the default versions of nodes matching `name` (the default) or all versions of the nodes.
GetNodeByIdentifier().
#### Parameters
- **name** (`str`) –
- **sourceTypePriority** (`NdrTokenVec`) –
- **filter** (`VersionFilter`) –
### GetNodeByNameAndType
A convenience wrapper around `GetNodeByName()`.
Instead of providing a priority list, an exact type is specified, and `nullptr` is returned if a node with the exact identifier and type does not exist. Optionally, a filter can be specified to consider just the default versions of nodes matching `name` (the default) or all versions of the nodes.
#### Parameters
- **name** (`str`) –
- **sourceType** (`str`) –
- **filter** (`VersionFilter`) –
### GetNodeFromAsset
Parses the given `asset`, constructs a NdrNode from it and adds it to the registry.
Nodes created from an asset using this API can be looked up by the unique identifier and sourceType of the returned node, or by URI, which will be set to the unresolved asset path value.
`metadata` contains additional metadata needed for parsing and compiling the source code in the file pointed to by `asset` correctly. This metadata supplements the metadata available in the asset and overrides it in cases where there are key collisions.
`subidentifier` is optional, and it would be used to indicate a particular definition in the asset file if the asset contains multiple node definitions.
`sourceType` is optional, and it is only needed to indicate a particular type if the asset file is capable of representing a node
# Definition of Multiple Source Types
Returns a valid node if the asset is parsed successfully using one of the registered parser plugins.
## Parameters
- **asset** (`AssetPath`) –
- **metadata** (`NdrTokenMap`) –
- **subIdentifier** (`str`) –
- **sourceType** (`str`) –
## GetNodeFromSourceCode
Parses the given `sourceCode` string, constructs a NdrNode from it and adds it to the registry.
The parser to be used is determined by the specified `sourceType`.
Nodes created from source code using this API can be looked up by the unique identifier and sourceType of the returned node.
`metadata` contains additional metadata needed for parsing and compiling the source code correctly. This metadata supplements the metadata available in `sourceCode` and overrides it in cases where there are key collisions.
Returns a valid node if the given source code is parsed successfully using the parser plugins that is registered for the specified `sourceType`.
### Parameters
- **sourceCode** (`str`) –
- **sourceType** (`str`) –
- **metadata** (`NdrTokenMap`) –
## GetNodeIdentifiers
Get the identifiers of all the nodes that the registry is aware of.
This will not run the parsing plugins on the nodes that have been discovered, so this method is relatively quick. Optionally, a "family" name can be specified to only get the identifiers of nodes that belong to that family and a filter can be specified to get just the default version (the default) or all versions of the node.
### Parameters
- **family** (`str`) –
- **filter** (`VersionFilter`) –
## GetNodeNames
Get the names of all the nodes that the registry is aware of.
### Parameters
- **family** (`str`) –
## Get the names of all the nodes that the registry is aware of.
This will not run the parsing plugins on the nodes that have been discovered, so this method is relatively quick. Optionally, a "family" name can be specified to only get the names of nodes that belong to that family.
### Parameters
- **family** (`str`) –
## Get all nodes from the registry, optionally restricted to the nodes that fall under a specified family and/or the default version.
Note that this will parse all nodes that the registry is aware of (unless a family is specified), so this may take some time to run the first time it is called.
### Parameters
- **family** (`str`) –
- **filter** (`VersionFilter`) –
## Get all nodes matching the specified identifier (multiple nodes of the same identifier, but different source types, may exist).
If no nodes match the identifier, an empty vector is returned.
### Parameters
- **identifier** (`NdrIdentifier`) –
## Get all nodes matching the specified name.
Only nodes matching the specified name will be parsed. Optionally, a filter can be specified to get just the default version (the default) or all versions of the node. If no nodes match an empty vector is returned.
### Parameters

- **filter** (`VersionFilter`) –
## Get the locations where the registry is searching for nodes.
Depending on which discovery plugins were used, this may include non-filesystem paths.
## SetExtraDiscoveryPlugins
→ None
## SetExtraDiscoveryPlugins
Allows the client to set any additional discovery plugins that would otherwise NOT be found through the plugin system.
Runs the discovery process for the specified plugins immediately.
Note that this method cannot be called after any nodes in the registry have been parsed (eg, through GetNode*()), otherwise an error will result.

Node%20Registry%20Model.md | # Node Registry Model
## Node Registry Model
![Permalink to this headline]()
Now let’s look at how we build the node list in the left panel of our example to show all the available nodes.
First of all, we need a model to manage the node data and we use a tree-view model for that in the omni.kit.graph.editor.example. Our NodeRegistryModel is derived from the basic `ui.AbstractItemModel`.
Each tree leaf item is derived from `ui.AbstractItem` which is used to encapsulate the data of the item which could contain the name, icon, url, etc. These data can be described by different value models inherited from `AbstractValueModel`.
There are a couple of important model APIs to define the tree model. `get_item_children` is the function to return the nodes at each level. For example, in the above image, the return value when input item is None will be [General, Miscellaneous], and the return value when input item is Miscellaneous is [Backdrop, Scene Graph, Input, Output].
`get_item_value_model` returns the value model which is the model that defines how each tree item is presenting its data. In the example, we only used the SimpleStringModel. But any model derived from `AbstractValueModel` will do, so you can define your own value model to describe a certain type of data.
## Node Filter
![Permalink to this headline]()
You probably noticed that there is a search field above the node lists, where you can search desired nodes with partial input. The results will be filtered to be the nodes matching the search input. This is done by controlling the visibility of the tree item in our example. If the item has name or information matching the input, the visibility is true otherwise false. The group visibility is controlled by each of the items inside. As long as one of the sub items is visible, the group visibility will be true.
## Quick Search Model
![Permalink to this headline]()
In the example extension, when you press the Tab key on the canvas, you will see a pop up window of QuickSearch. This will show all the nodes which are registered with quick search in the extension, which is a quicker way to find the node you want if you have many extensions registered to the quick search.
It is trivial to implement QuickSearch. You will need to create a new model for that, NodeRegistryQuickSearchModel in our example. It could be very similar to the NodeRegistryModel discussed above. The only difference is `get_item_children` will return all the nodes available grouped by different registrations since we don’t want the hierarchical look like the node registry panel.
To register with QuickSearch, we just need to import QuickSearchRegistry from omni.kit.window.quicksearch and register NodeRegistryQuickSearchModel with QuickSearchRegistry() using `register_quick_search_model`. You can create a tree delegate for the quick search. In the example, we just use the default GraphEditorCoreTreeDelegate from graph core. |

NodeDescriptionEditor.md | # Node Description Editor
The OmniGraph node description editor is the user interface to create and edit the code that implements OmniGraph Nodes, as well as providing a method for creating a minimal extension that can be used to bring them into your application. The window can be opened through the **Window -> Visual Scripting** and will look something like this when you open it:
The files it will create include the .ogn file that describes the node contents, a basic .py file that provides a template for writing your node’s computation algorithm, and the `config/extension.toml` file required by any extension to make nodes visible in the Omniverse environment.
Follow along with the external tutorial to see how this editor can be used to create an OmniGraph node in Python.
> **Warning**
> This editor was created as a quick prototype to help users who are not very technically proficient get up and running with creating OmniGraph nodes. There are many shortcomings in this editor and there is a plan to replace it with something more robust, complete, and modern in the future. You can use it for basic implementations but for anything more complex you will want to consult the documentation on **OmniGraph Nodes** and the **OGN User Guide**. |
node_architects_guide.md | # OmniGraph Node Architects Guide
This outlines the code that will be generated behind the scenes by the node generator from a .ogn file. This includes the API presented to the node that is outlined in [OGN User Guide](#ogn-user-guide).
As the details of the generated code are expected to change rapidly this guide does not go into specific details, it only provides the broad strokes, expecting the developer to go to the either the generated code or the code generation scripts for the current implementation details.
## Helper Templates
A lot of the generated C++ code relies on templates defined in the helper files `omni/graph/core/Ogn*.h`, which contains code that assists in the registration and running of the node, classes to wrap the internal data used by the node for evaluation, and general type conversion assistance.
None of the code in there is compiled so there is no ABI compatibility problem. This is a critical feature of these wrappers.
See the files themselves for full documentation on what they handle.
## C ABI Interface
The key piece of generated code is the one that links the external C ABI for the compute node with the class implementing a particular node’s evaluation algorithm. This lets the node writer focus on their business logic rather than boilerplate ABI conformity details.
The actual ABI implementation for the `INodeType` interface is handled by the templated helper class `OmniGraphNode_ABI` from `OgnHelpers.h`. It implements all of the functions required by the ABI, then uses the “tag-dispatching” technique to selectively call either the default implementation, or the one provided by the node writer.
In turn, that class has a derived class of `RegisterOgnNode` (defined in `OgnHelpers.h`). It adds handling of the automatic registration and deregistration of node types.
Instantiation of the ABI helper class for a given node type is handled by the `REGISTER_OGN_NODE()` macro, required at the end of every node implementation file.
## Attribute Information Caching
ABI access requires attribute information be looked up by name, which can cause a lot of inefficiency. To prevent this, a templated helper class `IAttributeOgnInfo` is created for every attribute. It contains the attribute’s information, such as its name, its unique handle token, and default value (if any). This is information that is the same for the attribute in every instance of the node so there is only one static instance of it.
## Fabric Access
This is the core of the benefit provided by the .ogn generated interface. Every node has a `OgnMyNodeDatabase` class generated for it, which contains accessors to all of the Fabric data in an intuitive form. The base class `OmniGraphDatabase`, from `OgnHelpers.h`, provides the common functionality for that access, including token conversion, and access to the context and node objects provided by the ABI.
The attribute data access is accomplished with two or three pieces of data for every attribute.
- A raw pointer to the data for that attribute residing in the Fabric
- (optional, for arrays only) A raw pointer to the element count for the Fabric array data
- A wrapper class, which will return a reference object from its `operator()` function
The data accessors are put inside structs named `inputs` and `outputs` so that data can be accessed by the actual attribute’s name, e.g. `db.inputs.myInputAttribute()`.
## Accessing Data
The general approach to accessing attribute data on a node is to wrap the Fabric data in a class that is suited to handle the movement of data between Fabric and the node in a way that is more natural to the node writer.
For consistency of access, the accessors all override the call operator (`operator()`) to return a wrapper class that provides access to the data in a natural form. For example, simple POD data will return a direct reference to the underlying Fabric data (e.g. a `float&`) for manipulation.
Inputs typically provide const access only. The declaration of the return values can always be simplified by using `const auto&` for inputs and `auto&` for outputs and state attributes.
More complex types will return wrappers tailored towards their own access. Where it gets tricky is with variable sized attributes, such as arrays or bundles. We cannot rely on standard data types to manage them as Fabric is the sole arbiter of memory management.
Such classes are returned as wrappers that operate as though they are standard types but are actually intermediates for translating those operations into Fabric manipulation.
For example instead of retrieving arrays as raw `float*` or `std::vector<float>` they will be retrieved as the wrapper class `ogn::array` or `ogn::const_array`. This allows all the same manipulations as a `std::vector<float>` including iteration for use in the STL algorithm library, through Fabric interfaces.
If you are familiar with the concept of `std::span` an array can be thought of in the same way, where the raw data is managed by Fabric.
## Data Initialization
All of this data must be initialized before the `compute()` method can be called. This is done in the constructor of the generated database class, which is constructed by the ABI wrapper to the node’s compute method.
Here’s a pseudocode view of the calls that would result from a node compute request:
```cpp
OmniGraphNode_ABI<MyNode, MyNodeDatabase>::compute(graphContext, node);
OgnMyNodeDatabase db(graphContext, node);
getAttributesR for all input attributes
getAttributesW for all output attributes
getDataR for all input attributes
getElementCount for all input array attributes
getDataW for all output attributes
getElementCount for all output array attributes
return db.validate() ? OgnMyNode::compute(db) : false;
```
## Input Validation
The node will have specified certain conditions required in order for the compute function to be valid. In the simplest form it will require that a set of input and output attributes exist on the node. Rather than forcing every node writer to check these conditions before they run their algorithm this is handled by a generated `validate()` function.
This function checks the underlying Fabric data to make sure it conforms to the conditions required by the node.
In future versions this validation will perform more sophisticated tasks, such as confirming that two sets of input arrays have the same size, or that attribute values are within the legal ranges the node can recognize.
## Python Support
Python support comes in two forms - support for C++ nodes, and ABI definition for Python node implementations.
For any node written in C++ there is a Python accessor class created that contains properties for accessing the attribute data on the node. The evaluation context is passed to the accessor class so it can only be created when one is available.
The accessor is geared for getting and setting values on the attributes of a node.
```python
import omni.graph.core as og
from my.extension.ogn import OgnMyNodeDatabase
my_node = og.get_graph_by_path("/World/PushGraph").get_node("/World/PushGraph/MyNode")
my_db = OgnMyNodeDatabase(my_node)
print(f"The current value of my float attribute is {my_db.inputs.myFloat}")
my_db.inputs.myFloat = 5.0
```
Important
For Python node implementations the registration process is performed automatically when you load your extension by looking for the `ogn/` subdirectory of your Python import path. The generated Python class performs all of the

OgnAcos.md | # Arccosine
## Arccosine
Compute the arccosine (in degrees) of a scalar, array of scalars, vector, or array of vectors; in the latter three cases the arccosine operator is applied to every single scalar element in the corresponding structures. Note that each scalar element must lie in the domain [-1, 1], otherwise the computation will return NaN.
## Installation
To use this node enable `omni.graph.nodes` in the Extension Manager.

OgnAdd.md | # Add
Add two or more values of any numeric type (element-wise). This includes simple values, tuples, arrays, and arrays of tuples. If one input has a higher dimension than the other, then the input with lower dimension will be added to each element of the higher-dimension input.
Examples:
- scalar + tuple = resultTuple (where resultTuple is formed by adding scalar to each element in tuple).
- tuple + arrayOfTuples = resultArrayOfTuples (where resultArrayOfTuples is formed by adding each element in tuple with each corresponding element of each tuple in arrayOfTuples).
- scalar + arrayOfTuples = resultArrayOfTuples (where resultArrayOfTuples is formed by adding scalar to each element of every tuple in arrayOfTuples).
To add/remove addends on this node, select the node and press the small “+”/”-” buttons in the bottom-right corner of the “Inputs” widget in the “Property” window.
## Installation
To use this node enable `omni.graph.nodes` in the Extension Manager.

## Outputs
| Name | Type | Description | Default |
| --- | --- | --- | --- |
| Result (outputs:result) | bool | If ‘value’ is a scalar then ‘result’ will be true if ‘value’ is zero. If ‘value’ is non-scalar (array, tuple, matrix, etc) then ‘result’ will be true if any of its elements are zero. If those elements are themselves non-scalar (e.g. an array of vectors) they will be considered zero only if all of the sub-elements are zero. For example, if ‘value’ is [3, 0, 1] then ‘result’ will be true because the second element is zero. But if ‘value’ is [[3, 0, 1], [-5, 4, 17]] then ‘result’ will be false because neither of the two vectors is fully zero. | None |

OgnArrayInsertValue.md | # Insert Array Value
## Insert Array Value
Creates a copy of an input array with an element that has been inserted at the given index. The indexing is zero-based and clamped in such a way as to ensure that values of “Index” <= 0 result in the element getting inserted at the beginning of the array, while values of “Index” >= arrayLength result in the element getting inserted at the end of the array.

- **Type**: `['bool[]', 'colord[3][]', 'colord[4][]', 'colorf[3][]', 'colorf[4][]', 'colorh[3][]', 'colorh[4][]', 'double[2][]', 'double[3][]', 'double[4][]', 'double[]', 'float[2][]', 'float[3][]', 'float[4][]', 'float[]', 'frame[4][]', 'half[2][]', 'half[3][]', 'half[4][]', 'half[]', 'int64[]', 'int[2][]', 'int[3][]', 'int[4][]', 'int[]', 'matrixd[2][]', 'matrixd[3][]', 'matrixd[4][]', 'normald[3][]', 'normalf[3][]', 'normalh[3][]', 'pointd[3][]', 'pointf[3][]', 'pointh[3][]', 'quatd[4][]', 'quatf[4][]', 'quath[4][]', 'string', 'texcoordd[2][]', 'texcoordd[3][]', 'texcoordf[2][]', 'texcoordf[3][]', 'texcoordh[2][]', 'texcoordh[3][]', 'timecode[]', 'token[]', 'transform[4][]', 'uchar[]', 'uint64[]', 'uint[]', 'vectord[3][]', 'vectorf[3][]', 'vectorh[3][]']`
- **Description**: The array to be copied into the output array prior to element deletion.
- **Default**: None
### Index (inputs:index)
- **Type**: `int`
- **Description**: The index of the element that should be removed from the output array. Indices in the domain [0, arrayLength) correspond to the usual element locations in the array, e.g. an “Index” of 2 equates to the third element in the array. Indices in the domain [-arrayLength, 0) correspond to array indexing starting from the back of the list, e.g. for an array of size 5, an “Index” of -5 equates to the last element in the array (i.e. the element at position 4), an “Index” of -4 equates to the second-to-last element in the array (i.e. the element at position 3), etc. Attempting to compute this node with “Index” values outside of the [-arrayLength, arrayLength) domain will result in a runtime error.
- **Default**: 0
## Outputs
### Array (outputs:array)

OgnArraySetIndex.md | # Set Array Index
## Set Array Index
Creates a copy of an input array where an index-specified element has been given a new value. Positive indices index from the front of the array, while negative indices index from the back of the array. “Index” values in the domain [-arrayLength, arrayLength) will always be valid for this node type. If “Resize to Fit” is true and “Index” >= arrayLength, then the output array will be resized to length 1 + “Index” and fill the new spaces with zeroes before applying the new element value.
## Installation
To use this node enable `omni.graph.nodes` in the Extension Manager.

OgnArraySlice.md | # Get Array Slice
Returns a section of the input “Array” between the index values of “Start Index” and “End Index” (or the end of “Array” if the input “Use Length” is true). The index values will be truncated to be within the range of the input array. If “Start Index” is greater than or equal to “End Index” then an empty array will be outputted. Note that the element at “End Index” (assuming said index is not greater than or equal to the input “Array” length) will not be included in the final result.

OgnATan2.md | # Arctangent2
## Arctangent2
Computes the angle in degrees between the positive x-axis and the vector from the origin to the input point ("X Axis", "Y Axis") in the range [-180, 180], also known as the 2-argument arctangent. The inputs can take the form of simple values, tuples, arrays, and arrays of tuples. If one input has a higher dimension than the other, then the input with lower dimension will be repeated to match the dimension of the other input (broadcasting), and the output will have the same shape and size as the higher-dimensioned input.

OgnBestPractices.md | # .ogn Best Practices
## Customize Your Node Type
### “icon”
You can add a custom icon in the form of a .svg file to represent your node type in the graph editors. The easiest way is to put it in the file `OgnYourNode.svg` alongside your `OgnYourNode.ogn` file. If you do this then you do not need to add the “icon” keyword to your .ogn file. If you put it in any other location, for example if you want to share a single icon among multiple nodes, then use the “icon” keyword to specify the location.
The image should be evocative of the function of the node type, yet not overly complex. Here are some examples for a node type that capitalizes a string.
| Okay (from category) | Better (shows result) | Best (shows function) |
|----------------------|----------------------|----------------------|
|  |  |  |
### “categories”
Choose a meaningful but targeted list of “categories”. The node type library groups node types using this information so by specifying them you put your node type definition alongside other similar ones. Here’s what you might put in for a node type that multiplies two matrices together.
| Okay | Better | Best |
|------|-------|------|
| “math” | “math:operator” | [“math:operator”, “math:matrix”] |
### “ui_name”
This is the name that users will see in the interface so make it meaningful! The .ogn will give you a default based on your node type name but you can usually come up with something better if you name it manually. It’s usually better for the name to answer the question “what does it do” rather than “what is it”, as you would prefer the active voice over
# the passive voice in documentation.
## description
### “description”
This is the core piece of information that your node type definition uses to convey to the user exactly what the node type does, and why they would want to use it. It should fit into a reasonable sized tooltip, and not contain any specialized formatting. That can be reserved for the more detailed documentation you can add by creating a pre/post documentation file (e.g. OgnYourNode.pre.rst and OgnYourNode.post.rst, where you write sections of restructuredText that will appear before and after the automatically generated node type documentation). It should also be read as a complete, grammatically correct sentence.
The text of the description should be detailed enough to get a basic understanding of how the node type works, with attribute-specific details in the respective attribute’s descriptions. You will have to balance the need for precision with the desire for brevity.
| Okay | Better | Too Far? |
| --- | --- | --- |
| Concatenate two strings. | Output the string that results from concatenating the two inputs strings. | Creates a single output “Result” that is formed by taking the input string in “Prefix” and appending the input string in “Suffix” to it. For example, inputs of “hello” and “world” will create the output string “helloworld”. |
## attribute-definitions
### The attributes also have user visible facets that should be made clear in order to make your node type more understandable. In particular, the user should be able to look at the attribute names and descriptions and relate them precisely to their function in the node type, knowing what kinds of values to use for inputs and what will appear on the outputs.
### “attrName”: “ui_name”
As with node types the attributes will have a specific name that the user sees and interacts with in interfaces such as the property panels and the graph editor. The UI name should be as descriptive of the attribute as possible without being overly long, cluttering up the interface. In our string concatenation example above the names can substitute for more verbose descriptions.
| Good | Better | Best |
| --- | --- | --- |
| A | First | Prefix |
| B | Second | Suffix |
| C | Result | Concatenation |
### “attrName”: “description”
As with the node type, the description is the primary source of information for the user on exactly how an attribute will be used and what values inputs can take. It should also be sized and formatted to fit into a tooltip, and read as one or more complete, grammatically correct sentences. The attribute “Prefix” above might be described as follows:
| Good | Better | Best |
| --- | --- | --- |
| First string. | First half of the output string. | The first part of the string that will form the concatenated output. |
### “attrName”: “type”: “execution”
Attributes of this type are used for the Action Graph to define and trigger subsections of a graph for evaluation when certain events happen. As all attributes of this type are essentially used for the same thing the wording for their descriptions should be consistent.
The naming conventions are already somewhat consistent for the generic execution attributes, usually “inputs:execIn” for input signals and “outputs:execOut” for output signals. Special purpose node types that contain multiple execution attributes, such as **omni.graph.action.Countdown**, use a variety of different names that are more indicative of their exact function, as they should.
Normally, the descriptions will tell the user what values are represented by the attributes, however these types of attributes have a limited set of values that are generically described elsewhere so the descriptions in the node type definitions should tell the user when they are triggered.
| Commonly Seen | Better |
|---------------|--------|
| Input execution | Signal to the graph that this node is ready to be evaluated. |
| Commonly Seen | Better |
|---------------|--------|
| Output execution. | Signal to the graph that evaluation should continue downstream. |
| Good | Better |
|------|--------|
| Triggered after duration ticks is finished. | Output execution signal, triggered after the node has been successfully evaluated a total of “Duration” times after the input “Exec In” signal has been triggered. |
| Triggered every ‘period’ ticks | Output execution signal, triggered every “Period” successful evaluations, stopping after the “Finished” execution pulse is triggered. |
| Generic | More Specific |
|---------|--------------|
| Signal to the graph that this node is ready for execution. | Signal to the graph that this node is ready for execution. When the node executes with this signal active it plays the clip from the current frame. |
### “attrName”: “type”: “bundle”
A “bundle” type is used as a short form for “a bunch of attributes that will be defined at runtime”. Often, the definition of what is expected in a bundle is partially or fully known when constructing the node type so that information should be surfaced as part of the attribute description.
| Good | Better | Best |
|------|--------|------|
| The input bundle. | Input bundle representing a mesh to be operated on. | Bundle minimally consisting of a **pointf[3][]** attribute named “points” and a **normalf[3][]** attribute named “normals” defining a basic mesh structure. |
| Good | Better | Best |
|------|--------|------|
| Bundle | Mesh Bundle | Points and Normals |
## General Naming And Description Tips
You can go a long way to figuring out if your names and descriptions are intuitive by looking at a graph in the graph editor and trying to read it as an english sentence.
As an example (where descriptions are **bold** and names are *italicized*) - take two *Constant Integer* values, **Add the two values together** to get the *Sum* of them. Using the *Sum* as an *Index* into an *Array* of values, **Select the element at the *Index* position in the *Array*,** and put the result in the *Selected Value*.
Here are some more specific tips that will help make the user’s experience with your node type more pleasant.
- **Avoid short forms in user-facing names and descriptions.**
| Avoid | Prefer |
|-------|--------|
| pts | Points |
| int | Integer, 32-bit Integer |
| xform | Transform |
* **Explain or provide references for any terms that are not obvious from context.**
| Avoid | Prefer |
|-------|--------|
| This node type lets you access a Variant Set | This node type lets you access a Variant Set. For more information on Variant Sets see |
* **Be precise with names whenever possible.**
| Avoid | Prefer |
|-------|--------|
| Input Value | Angle |
| Output Value | Cosine |
* **Include in the description the conditions in which a node type compute() can fail.**
| Avoid | Prefer |
|-------|--------|
| Sets the output to the result of the numerator divided by the denominator. | Sets the output to the result of the numerator divided by the denominator. Fails if the denominator is approximately equal to zero. |
* **Be wary of ambiguous verbs. In a node type that multiplies two matrices describing the output as “The modified matrix” could either mean “A copy of the matrix with the modifications performed on it” or “The original matrix, modified by the multiplication”. The difference is important as the second implies that the original matrix is lost.**
| Avoid | Prefer |
|-------|--------|
| The modified matrix. | The product of the two input matrices. |
* **Use roles when they are appropriate.**
| With This Description | Avoid | Prefer |
|-----------------------|-------|--------|
| The points to deform. | float[3][] | pointf[3][] |
| The color whose luminance is to be computed. | double[3] | colord[3] |
* **The name of the attribute need not repeat the type unless it is need for clarification.**
| Avoid | Prefer |
|-------|--------|
| Prefix String | Prefix |
| Largest Integer | Largest |
| Blended | Blended Color |
- **UI names are always capitalized, and multiple word names are separated by spaces.**
| Avoid | Prefer |
|-------|--------|
| transform | Transform |
| BlendedColor | Blended Color |
| xAxis | X Axis |
- **When input attributes are equivalent, more generic names can be used. For example although the names are generic there is no confusion here between the inputs.**
| Name | Attribute Description |
|------|-----------------------|
| A | The first of the two strings from which to find the longest. |
| B | The second of the two strings from which to find the longest. |
| Longest | The longest of the two input strings A and B. |
- **When referring to the attribute names in the node type description use the UI name since the UI is where the text will be read. In particular you can always omit the “inputs:” and “outputs:” namespaces when referring to attributes.**
| Avoid | Prefer |
|-------|--------|
| The longest of the two input strings “inputs:a” and “inputs:b”. | The longest of the two input strings “A” and “B”. |
- **Nodes are “executed”, attributes are “computed”**
| Avoid | Prefer |
|-------|--------|
| When the node evaluates, calculate the output ‘RESULT’. | When the node executes, compute the output ‘RESULT’. | |

OgnBundleInspector.md | # Bundle Inspector
This node creates independent outputs containing information about the contents of a bundle. It can be used for testing or debugging what is inside a bundle as it flows through the graph. The bundle is inspected recursively, so any bundles inside of the main bundle will have their contents added to the output as well. The bundle contents can be printed when the node executes, and it passes the input straight through unchanged, so you can insert this node between two nodes to inspect the data flowing through the graph.
## Installation
To use this node enable `omni.graph.nodes` in the Extension Manager.
## Inputs
| Name | Type | Descripton | Default |
|-----------------------|---------------|-------------------------------------------------|---------|
| Bundle To Analyze | bundle | The bundle to be inspected. | None |
| Exec In | execution | Signal to the graph that this node is ready to be executed. | None |
| Inspect Depth | int | The depth that the inspector is going to traverse and print. For example, 0 means just attributes on the input bundles. 1 means its immediate children. -1 means the entire recursive contents of the bundle. | 1 |
| Print Contents | bool | If true then the contents of ‘Bundle To Analyze’ will print when the node executes. | False |

OgnCeil.md | # Ceiling
## Ceiling
Compute the ceiling value of a scalar, array of scalars, vector, or array of vectors; in the latter three cases the operator is applied to every single scalar element in the corresponding structures. The ceiling (sometimes shortenend to ceil) of a real number “A” is defined to be the smallest possible integer that is still greater than or equal to “A”.

OgnClamp.md | # Clamp — kit-omnigraph 1.143.1 documentation
## Clamp
Clamp a number or array of numbers to a specified range. If an array of numbers is provided as the input and lower/upper are scalars then each input numeric will be clamped to the range [lower, upper]. If all inputs are arrays, clamping will be done element-wise, where “Lower” and “Upper” are applied individually to each element in “Input”. An error will be reported if “Lower” > “Upper”.

OgnCompound.md | # Example Node: Compound
Encapsulation of one more other nodes into a single node entity. The compound node doesn’t have any functionality of its own, it is merely a wrapper for a set of nodes that perform a complex task. It presents a more limited set of input and output attributes than the union of the contained nodes to make it seem as though a single node is performing a higher level function. For example a compound node could present inputs a, b, and c, and outputs root1 and root2 at the compound boundary, wiring up simple math nodes square, squareRoot, add, subtract, times, and divided_by in a simple way that calculates quadratic roots. (root1 = divide(add(b, square_root(subtract(square(b), times(4, times(a, c))))))) (root2 = divide(subtract(b, square_root(subtract(square(b), times(4, times(a, c)))))))
