I'm pretty fine with the marble shader on my site. I just looked it over. For use in P8, you want to change the GC in there to 1.0 or perhaps use the latest hybrid GC+HSVETM I posted in the Dummy's Guide to IDL thread.

I'd also remove the AO - P8 IDL or light-based AO is better.

And don't be afraid to play with colors. At the top is a Blender with a shader of gray in there. Mess with that.

This was rendered in P8 with IDL and the hybrid GC+HSVETM settings.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
