In fact the latest MJ mapping just corrects the stretching of the sclera on SaintFox's texture. As far as I can see the current SF texture works perfectly with latest MJ mapping (see above image).

Yeah, I didn't think to mention that to you, but I guess I should have. I made sure that the iris mapping didn't move or change at all, but the sclera was completely redone and the corneas, which had been separate islands, were rejoined to the sclera.
