I brought a mesh and texture into Zbrush in order to fix the seems. Simple, I've done it before. I have a faily low-poly model and a 2k texture map.
I subdevide 7 times(ending at around 6 mill polies- having clicked smooth UV) and start painting out my seams. Once finished, I press "new from polypaint."
The next pixture will show you what happens. I get a strange pixeleted effect around my UV seams.
I get various versions of the same effect by playing around with thje UV map border slider and anti alias only blurs the strange pixels. Upping my UV map size reduces the size and therefore visibility of the artifacts, but they are still too visible - especially when I bring the texture back into Maya and render it.
Hope someone can help, seeing as noone I have talked to have seen this before. I have also attached a uv snap shot
