Can you copy the material itself to another object, such as the Poser single sided square? Then perhaps copy it back and see if that makes any difference. Or even save the material out on its own, just as a mt5,

Maybe even take a look at the model's cr2 after the materials have loaded, see if you can spot anything weird about that particular body part.

Other than that, I got nothin'.
