A friend asked me in a private message about making a particular kind of paint shader. Since there's a lot to write, and I need a lot of pictures to demonstrate, I thought I'd give a little tutorial on using matmatic to produce a general purpose shader, focusing on the easy generation of an accurate Fresnel effect.

I will be building the shader bit by bit. You can follow along if you like. At the end, I will attach the finished script for you to use. I will call this the BBGlossy shader.

Please hold questions until the presentation is complete.
 


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)
