I've been using 3d Coat for a bit over a month now and find it to be overall a very comfortable program. I have however been dealing with an issue that pops up fairly often. Seams Around the UV
edges. This tends to effect the Normal and the Diffuse in the same way. I did some experimentation and found that it seemed to be caused specifically by having slightly different and overlapping UVs. Unfortunately I'm making game assets and this comes up in a lot of different things. From what I can tell these are just pixels which seem to be only halfway inside the UV shell and amount to pixels I just can't paint on.
So far my solutions have been to place a plane in the scene that contains the entire texture sheet, allowing me to paint out the bad parts. this of course is not accurate because I'm doing each edge separately. There is also smudging the texture in Photoshop. Same problem. What I'm looking for ideally, is more padding controls within 3D Coat, but it tends to only adding the padding after export and it gets the bad part of the texture anyway. Any insights would be appreciated. Thanks in advance.
