Actually, I've been playing with that Nylons shader of Bill's and have made it GC... I think. I'm just clearing my Poser drive of old stuff (going on to my external) so give me a few minutes and I'll see what I can come up with.

Expert? Not by a long shot... but thank you for the compliment. I base my stuff on a Sherlock Holmes quote - used to be obsessed with Holmes, ideal man, I thought - which went:
"What one can invent, another can discover."

Generally holds true for just about everything except matmatic-generated shaders, since matmatic is very efficient and creates shortcuts / alternative node sets to what you would think.
