# Library

The Library is a scriptable object file that contains all the assets separated into properties like *3D Assets* for the prefabs, materials for the *Skyboxes*, and *Terrain Textures* for the Unity Terrain Layers. Furthermore it serves as a repository for all your custom properties, for example prefabs linked to custom mechanics.
