hey there.....
I am using Ryan Kingslien's "texturing with photo referance" technique to project an image onto a head, however when i drop projection master the texture seems to screw up. I've laid the uvs out maya and imported the .obj into zbrush.

here is an example of whats happening:




If I use GUV tiles this problem doesn't happen but makes any kind of photoshop work very difficult.

any help is greatly appreciated
