Keppel, so sharing bought Pose sets would be OK? Somehow I doubt that.

Ladonna, if you used BB's mathmatic script to generate the shader, you did not make the shader "from scratch". You just used the source code. 

You cannot copyright formulas, that would need a patent. But you should write your own source code if you want to avoid copyright problems, generally speaking.
