@ Cec - you annoying you. Every time I think I have grasped some basic concepts and get ready for trying a more life-like rendering than I have tried so far, you come up with more interesting information. Interesting, but kind of daunting. At least I am now confused at a higher level. Please keep sharing your techniques. And beautiful (but disturbing) images.

If you ever were to write a mini-guide for SH3D rendering, I volunteer as a proofreader / guinea pig to ask stupid questions.

ok
