Vertex Color Materials (Patreon)

In one of my upcoming videos im planning to show cheap ways to make a material breakup with lower drawcalls.

In this material we blend between 3 materials with vertex color to ID where they go on the mesh.

Each material allows for Albedo, Roughness, and Metallic controls. Combine this with a mask to tie them together and add more albedo/roughness details and your in a super nice spot.
