Is it possible to control how many and what is in a single material? For reference my use would be in game dev and I would like to control how many materials each character has such as this with 1 for hair, 1 for face, 1 for torso, 1 for legs/feet. Same goes with clothing, 1 for hair, 1 for face, 1 for skin, 1 for shirt, 1 for pants, 1 for shoes.
