 # Prefabs
 
-The **Prototyping Kit** comes with several prefab objects, primarily for blocking out levels. The grid prefabs, such as the `Grid-Cube.prefab`, are the most commonly used objects as these are configured with a material selector and automatic tiling. Using the prefabs provides the most utility out of the box.

 ## 🀄 Automatic Tiling
 
-The grid and checkerboard prefabs have a [Material Tiling](/api/Zigurous.Prototyping/MaterialTiling) script that automatically tiles the material based on the object's size. This is very convenient so you do not need to create different material variants for different sized objects. For cubes, this is made possible from a custom mesh applied to the object.
