What was your intended application for this paint, Bill? Eye shadow? Blusher? I can't tell from your code or from the explanation. Sorry.

I didn't have anything in mind. My point was that from the standpoint of the CSB concept, there's no difference between a color overlay, a bump overlay, a shine overlay, or any combination of these things. The different sections can be as wildly different as you like. CSB captures the essence of an extraordinary number of real-world materials.

Further, the mixing of CSBs encapsulates both the cases where you're dividing a surface into distinct, hard-edged regions, as well as smoothly blending one area into another - that's just a function of the gradients contained in the mask.
