I'm sure I have this somewhere, though it's an awkwardly large model.

Something to check on is how any bump-mapping is done. The "Gradient Bump" option only works when you use the P4 shading engine, in the later versions of Poser. If you have bump-mapping connected to the Gradient Bump, it will be worth changing that the the ordinary Bump input, and seeing what happens.

This was all a long time ago, and P4-compatible materials can do some odd things in P5 and later. From what I've seen, DAZ Studio does an imperfect job of converting materials settings, too.
