You had mentioned, Bill, in a different thread about possibly writing a book about shaders. Just as any programming book ends with some obligatory product template, yours could end with some finalized version of your skin shader AND VSS Pro and the whole shader concept could be led from matmatic to nodes in the mat room, with a whole lot of maths explained and wow, what a book THAT would be.

Ever since you gave me that brilliant recipe for a BASIC skin shader, Bill, I've been playing ever so much with matmatic tweaking it, mucking around with masks and even blending shader-based make-up with jpg-painted makeup (customer request) and VSS made the process SO quick and simple. No, I'm not about to write a tutorial on either tool - what you wrote earlier in this thread more than adequately explains the Versatile Shader System's use, but jeez, even if this is the state of the product for now... WHAT a product!!

I hate to admit it but I haven't even begun to explore all the stuff you gave along with matmatic and VSS.

Let's play with this for a bit longer, folks. I'm having WAY too much fun with it as it is, and all I can say is: what an incredible set of tools JUST the way they are. I am deeply grateful to Bill for these fantastic gifts that have made Poser a much richer 3D art environment even for those of us (well, me, in this case) who aren't proper artists.
