Quote - Cool.  Thanks for showing us the matmatic formulas.  I have downloaded your second material set.  Now if I could just figure out which among the 68 nodes plus belong to above matmatic formulas...

Short answer: you probably won't. Matmatic is an incredible tool in that it optimises Poser node creation based on the formulas... IOW, it's not a one-to-one relationship, i.e., "this function generates that node".
I did try that once, and was set straight. Unequivocally. :biggrin:

The best thing to do is try to understand the logic behind the math - which is what you're doing - and not worry about what nodes are created: it's going to be node soup, anyway.

On a side note, Matmatic provides about the very best shader copyright protection out there, since without the script no one can reverse-engineer the nodes to recreate the formulas that generated them. Well, I say no-one, but I'm sure someone from the planet Brainiac might be able to nut out something, but believe me, as Bagginsbill's scripts go, you'd have to have pretty much his intellectual horsepower to even get close to sorting out what made what.
