When I paint on this texture and save, it kind of resets at the seams and gets these strange parts (didn't happen with another texture):
The .jpg that is saved contains these strange little grainy textures at the seams again.
Also when I paint at these spots with the draw brush and save, it kind of makes the new drawn color transparent over the grainy texture and shows it up again. It is only at the seam, tried to work around it but I don't have a clue what causes it.
I guess this might have happened to someone else and probably asked before, so I apologize for a possible double question.
