Oh - and of course Math and Color_Math, although there's nothing to understanding the node's themselves. Rather, you need to know when to add two things or multiply two things. And matmatic will almost always take care of building those for you anyway, or eliminating them when there is a way to do so.
For example, the expression a + b may result in a Math, or a Color_Math, or nothing at all. Depends on what a and b are set to.
a = RED
b = BLUE
a+b = MAGENTA
a = 1
b = 3
a+b = 4
a = Diffuse()
b = Blinn()
a+b = a Color_Math:Add node connected to a and b
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)
