Thank you so much, Bagginsbill!  You are awesome.

You have given me enough information that  I think I can go off and learn on my own for quite some time.  Researching on my own before I had no idea what to do to create my own shader, because there seems to be absolutely zero info out there about creating shaders for Poser specficially.

Also, its possible that your shader will do what I want already, so maybe I don't need to do that, but I'm a programmer too, so I'm itching to see what I can do with my new found knowledge.  ATM, I have been rolling my own toon shading with a script that I wrote to string together about 7 nodes, none of which are the toon shader node. :-)

I'll try your shader out as soon as I have a chance. 

Thanks again!
