That was exactly my experience with vss.  Started out as just using it for a great skin shader but then as I explored more I realized the potential.  Now I'm waiting for my next vacation when I can finally sit down and tinker with matmatic!

I really do hope BB can put out a pro version with all the settings he mentioned in an older thread.   I realize he probably makes much more than he would with a pro version for sale but at least he'd get some kind of reward for all the time and effort he's put into making us understand the Poser shader system.

Please think about it BB :)
