Oh - I just noticed you mentioned Poser 8 versus PP2012, the shader produces a very different outcome. Are you now rendering with linear workflow (render GC) ?

This is a shader that is strongly affected by linear versus non-linear color space. The parameters end up having a very different influence bewteen the two. It's one of the reasons my shaders are 80 nodes instead of 8 - having to build into it the ability to detect linear workflow, and if it's not active, to do linear itself.

Are you looking for a single shader that produces the same outcome in both, as my shaders do?

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)
