Quote - When you get a change, BB, what I'm much more curious to see is the .mm1, if you're willing to share that. Or did you do all this sans scripting?

I have to publish the new version of matmatic before you can use the script.

Also, I'm still not convinced I've taken everything into account yet. I'm making some simplifying math assumptions that I have yet to justify, except for the fact that the shader looks pretty convincing.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
