Sounds great, and looking forward.

The parameter dial materials dependencies you speak of were in fact implemented in the past by the mat room wizard Bagginsbill. He called it Parmatic. IIRC he never went too far with the implementation, or rather it was probably too complex for casual users maybe. He had a few different Pre Superfly mat room formulas that were pretty complex; one was VSS and he also had a mat room automation called Matmatic which would later be refined and supplanted by Snarlygribbly's Eskin python utility.

It became much easier to set up such dependencies when Poser 8 introduced the editor, prior to that the code had to be hacked in via text editing. You can find BB's Parmatic here...

I'll PM you soon but will really only be useful for commentaries on texture and morph qualities for suggestions I'd imagine. I'll have to take a look.
