I HAVE CREATE MY OWN SOLUTION, NO NEED TO ANSWER.
So, I’ve hit a road block, where I want to use different materials, but somehow apply changes to a texture universally. What I’m basically doing is applying a grunge texture to every material, but I’d like to keep the settings uniform across each material, so: Influence, Mapping, things of that nature. I need them to maintain settings after the materials are already created. In other words, if I have already created 50 materials with the same texture applied, and then realize I don’t like something, like the blending mode, I can change it one material and have it applied to every material with the same texture.
Surely I’m overlooking something. I’d do it in post, but I like the effects I can create by applying the textures before the render.
Also, I am using the Internal Render, since my shaders are not complex enough to justify additional render times.
