Oh my, I just barely, and thankfully, saved supper from burning. When this forum gets busy, and interesting, one really cannot cook a meal, and read and digest the posts at the same time.

This really is a matter of process. You are trying to push Poser beyond what the programmers intended. And you are doing an astounding job of it.

It sounds as if your insertion pose is almost like a CR2 file (geometry and rigging). Can a PMD be associated with (or embedded in) a PZ2 file?

I am not a Poser guru of any type, not even the material room. But, with blenders, masking maps, and nodes, one can mix materials on the same material zone. One can even blend or mix displacment (this takes a lot of trial and error). It sounds like Cage has better answers than I have questions or suggestions, but the material room still holds a lot of promise as a way to refine your end results even more.
