Their names should be self explanatory, but for those who don’t know albedo materials keep the default colors and texture, it just applies a filter to it. Material_Albedo, material_black, material_metal_Clearcoat, and material_white.
It’s great for making materials shiny, works great for rubber, plastic, and even eyes! I like using it on my model’s eyes to add some shine~ ClearCoat is next! It’s one of my favorites to use, since I really love glossy objects.
