I just tried looking at the cr2 file in Poser File Editor, comparing Nykta with the PHC texture applied and the original file, but it is as I said previously: I don't understand what I am looking at, or even know what I am looking for. To me, the cr2 files look the same. I have tried everything I can think of, it happens on two of my machines running Poser Pro 2014, with the most current SR, Peggy/P3D-Art has never seen this before and 01Sculp behaves normally for her, and so far no one on the forum has come forward having this problem themselves...

I'll just live with it, and hope the problem never happens on something with a more complex shader.
