The TerraBlender library is often needed to play with mods that add new biomes to Minecraft. It makes it much easier for developers to modify the world generation. However, if the mod manual does not require it, you will not need this library since it does not affect the generation or other parameters in any way.
How to install TerraBlender
- Make sure you have installed Fabric Mod Loader and Fabric API.
- Download the mod for your version of the game.
- Put it in the ‘mods’ folder, which is located in the game folder.
