So I'm currently polypainting a model, I've done this process many times but never came across this issue before.
This is it on subdivision 4:

And this is it on subdivision 8:
![subdivis8_zpspgvt4dk4.jpg](http://i16.photobucket.com/albums/b28/pepermints/subdivis8_zpspgvt4dk4.jpg)
It looks like a bad image compression or something. Even if I fix the polypaint up in the highest subdivision if I scrub up or down on the subdivisions the artifacts appear again...
Any ideas why? Thanks
