Thanks, cobaltdream. That's the funny thing... I had the same thought, and so I did look over the synchronization report. But as far as I could tell, everything was right.

However, I did reload the original texture, and my new render was fine. It seems that it was a glitch, but I have no idea what caused it, unless somehow something in Poser's brain was retaining some of the info from VSS1 which I had been using previously but had deleted.

All I know is that I have renders of pretty much every V4 hair in my runtime using that same texture (but without VSSPR3), and there was no such divergence in the texture.

So I'm at a loss, but at least it seems to be working now.
