ashleygoldstein/LWM-Warehouse-Scene/README.md | # LWM-Warehouse-Scene
This Sample was developed during the Learn With Me livestream Series.
Learn With Me streams every Monday and Wednesday at 1pm EST on the NVIDIA Omniverse Twitch and YouTube channels
https://www.youtube.com/@NVIDIAOmniverse/streams
Playlist of the previously recorded streams:
https://youtube.com/playlist?list=PLPR2h_elPvVKH9HLtdgfXNUxGeN6QAlc7
This USD works in Omniverse USD Composer (fka Create) and Isaac Sim 2022.2.0 and later versions.
Check out the Tests folder for simple test scenes.
Contributors/Inspired Authors:
Alberto Arenas / Omniverse Ambassador- Camera Constraint ActionGraph
Mathew Schwartz / NJIT - Behavior Scripts for Detecting Collision
Eric Craft / Mead & Hunt - Collision Detection OmniGraph
____________________________________________
Notes:
For the full sample scene to work, please download all of the .usd files in that folder as the main scene, Warehouse_Detect_Coll_OG, uses payloads of the graphs. If the graphs are not working, please ensure they are connected to the payload.
You must have Physx Graph enabled from the Extension Manager in order for the Counter graph to work.
If you add more packages to the scene, a Rigidbody with Colliders preset must be added, if not already on the package, then remove the Colliders from the Decal Mesh and the Scotch Mesh.

Vadim-Karpenko/omniverse-material-manager-extended/CHANGELOG.md | # Change Log
All notable changes to this project will be documented in this file.
## [1.1.1] - 2022-12-26
### Fixed
Support of Create 2022.3.1
## [1.1.1] - 2022-10-04
### Fixed
Convert icon and preview_image to png format
## [1.1.0] - 2022-09-26
### Added
#### Roaming mode (settings tab)
Allowing you to automatically select an object just by looking at it.
Note that this can cause difficulty when creating new objects with variants, so it's best to only enable this mode when your scene is ready for demonstration.
### Fixed
- Fixed possible crash caused by iterating through history of commands.
## [1.0.1] - 2022-08-26
### Added
- Support of a new version of viewport (Next viewport).
## [1.0.0] - 2022-08-18

Vadim-Karpenko/omniverse-material-manager-extended/README.md | # Material Manager Extended
### About
This extension will let you quickly toggle between different materials for the static objects in your scene.
## Quick links
* [Installation](#installation)
* [Restrictions](#restrictions)
* [How to use](#how-to-use)
* [Linking with an Omniverse app](#linking-with-an-omniverse-app)
* [Contributing](#contributing)
* [Changelog](CHANGELOG.md)
## Installation
To add a this extension to your Omniverse app:
### From Community tab
1. Go to **Extension Manager** (Window - Extensions) — Community tab
2. Search for **Material Manager** extension and enable it
### Manual
1. Go to **Extension Manager** (Window - Extensions) — **Gear Icon** — **Extension Search Path**
2. Add this as a search path: `git://github.com/Vadim-Karpenko/omniverse-material-manager-extended?branch=main&dir=exts`
3. Search for **Material Manager** extension and enable it
A new window will appear alongside the Property tab:
## Restrictions
- Some vegetation can cause problems, but most should work just fine.
- Currently has no support of instanced meshes (they usually greyed out and aren't accessible).
- Your object needs to have the following structure:
Most objects already have this structure, especially from **Nvidia Assets** tab, but in some custom cases, you might need to change your object so it corresponds to the structure from above. Note: Looks folder can be empty, and your original textures located somewhere else, it just tells the extension that this is a separate object.
#### Example:
- It will not work with the primitives, because it does not corresponds to the structure from above.
## How to use
- Navigate to your viewport and select any static object on your scene
- Once an object is selected and is valid (see restrictions), the window will be changed into something similar to this:
- Click **Add new variant** at the bottom of the window. A new variant called _Look_1_ will appear in the list. You can create as many as you need, and if you need to rename your variant you can do it by renaming appropriate folder in **Looks/MME/your_variant**
- You will see a viewport window on top of your model. Change material or replace it completely while your variant is active
 
- Now you can toggle between those variants
 
- More complex Xform's are also supported. This means that the extension will toggle all the materials for every mesh at once under this Xform.
## Linking with an Omniverse app
For a better developer experience, it is recommended to create a folder link named `app` to the *Omniverse Kit* app installed from *Omniverse Launcher*. A convenience script to use is included.
Run:
```bash
> link_app.bat
```
There is also an analogous `link_app.sh` for Linux. If successful you should see `app` folder link in the root of this repo.
If multiple Omniverse apps is installed script will select recommended one. Or you can explicitly pass an app:
```bash
> link_app.bat --app code
```
You can also just pass a path to create link to:
```bash
> link_app.bat --path "C:/Users/bob/AppData/Local/ov/pkg/create-2022.1.3"
```
## Contributing
Feel free to create a new issue if you run into any problems. Pull requests are welcomed.
