How can be various textures up, layering them if you will, to build a displacement map that can be used for new materials and textures.
Demonstrating a metal material, creating a realistic, clean metal surface, and then converting that surface to reflect an aged and grungy metal surface.
Dustin demonstrates realistic plastic surfaces making the material clean and new and transforming it to a grungy surface.
Like the metal and plastics before, Dustin demonstrates how to apply wood materials to the model.
