Hi Mark, That's looking very good. And speed is quite ok imho. Most procedural materials are slower than textures anyway. Thank's for sharing! Arjo.
If it's too slow, for example in scenes with GI, it's possible to render a hires texture from this (camera straight from above) and use that texture instead of the procedural. But that consumes more memory - it's always a tradeoff...
thanks for the feedback & more to follow, -Mark H
