Installing Presets (1.12)

*This page is for the 1.12.2 version of OTG, for 1.16.5 instructions click here.*

*Note: Both servers and clients running OTG will require more memory than vanilla Minecraft. If you are experiencing long/endless world loading times or other performance issues it is recommended you increase Minecraft's allocated memory to 2gb+.*

## **Installing World Presets (1.12.2)**

### **Forge Single Player**

1. Install OTG
2. Download the .jar for your desired world preset from the links above and put it in the /mods folder.
3. Select the world from the world creation menu in game.

### **Forge Server**

1. Install OTG
2. Download the .jar for your desired world preset from the links above and put it in the /mods folder.
3. Go to the server.properties file and change the following two settings (replacing `**<worldname>**` with the name of the world preset (ie, level-name=Biome Bundle):

```
level-type=OTG
level-name=<worldname>

```

*Note: If you have already generated any chunks with vanilla or other world settings, delete the world folder of your main world to begin generating one with the correct level type.*

### **Spigot Server**

1. Watch the Video Tutorial or Follow the instructions below.
2. Install OTG
3. Run the server once to create the /plugins/OpenTerrainGenerator folder (delete the world afterwards).
4. Download the .jar for your desired world preset from the links above and **open it with WinRaR or 7zip (Do not put the world preset .jar in the plugins folder)**
5. The folder structure should be: `\assets\worldpacker\**<worldname>**` (where in place of `**<worldname>**` you will have the name of the world preset you downloaded (e.g Biome Bundle). Copy that folder to `\plugins\OpenTerrainGenerator\worlds` (in your server) If done correctly it'll look something like this:

```
\plugins\OpenTerrainGenerator\worlds\<worldname>
```
With the following subfolders:

```
\WorldBiomes\
\WorldObjects\
\WorldConfig.ini

```

Now go to the server.properties file and ensure that **level-name** is set to the world you're using (for instance, "Biome Bundle" without the quotes). *Note: If your spigot server uses a web control panel like McMyAdmin or similar, you may have to specify level-name there instead of in server.properties*

Add the following to your bukkit.yml to enable Open Terrain Generator and (for example) Biome Bundle for the default world (copy and paste this to get the correct leading spaces):

```
    generator: OpenTerrainGenerator

```

*In the above example Biome Bundle can be replaced with any other preset/world name matching any folder in the OpenTerrainGenerator/worlds folder.*

## **Manually installing a (non-jar) preset**

If you have an existing Terrain Control preset or an OTG preset not in .jar format but instead consisting of a world directory containing its Worldconfig.ini and WorldObjects and WorldBiomes subfolders, follow the installation instructions above but instead of installing a .jar file, put your world preset folder into the /OpenTerrainGenerator/worlds folder.

## **Generating a default 'vanilla worldgen' preset to edit**

If no world preset is installed, when generating a world OTG will generate a set of configs that approximate 'vanilla' Minecraft world generation in the /OpenTerrainGenerator/worlds folder (found in either the /mods or /plugins folder depending on platform).

Note: In Single Player (Forge) you can click the 'New' button to the right of 'Clone' in the world creation GUI to create a set of default configs without affecting any other installed presets.
