In the Ragdoll engine, a voxel's Material ID is its "DNA." It tells the engine what that voxel is made of and how it should behave in the physical world.
Note: Modders cannot create new Material IDs. You are limited to modifying the properties of the existing IDs (0-31) to suit your needs.
Below is a simplified reference for all defined Material IDs. Use this to choose the best base material for your modded blocks.
