Slight problem with texture and UV...

[t_smith5]

Okay, so, I've textured the head of a character model inside of ZBrush. Today, I went back to it to make some modifications/additions. However, when I add the texture and add a TurboSmooth modifier, some gaps are showing around the mouth. Looking at the UV, those affected areas now appear to be overlapping. 😕

The only solution I can think of is to move the affected areas and then collapse everything, which includes the TurboSmooth. Not ideal. Even if I move them and then turn off TurboSmooth briefly, and turn it back on, the problem returns.

Does anyone have any suggestions on how to overcome this problem? Thanks.
