To keep this short and simple, most of us know that different materials have different diffuse, normal, specular, and bump maps.
In the example below is a vehicle going back and forth from the Plastic material (more highlighted/bright) and Smooth Plastic (dull, mostly a single color) material. I’d like to keep the more 2 tone color on it by just disabling the diffuse texture of plastic. I cant imagine this to be a hard task as we’re using what we currently have and just allowing us to disable one of the textures used in this material.
(Hopefully you’ll be able to tell the difference from this angle, its more of a drastic change from other angles)
