UV seams issue on model w/Padding

I found some topics on the matter, but none of them seemed to solve the issue.

I'm currently having some issues with texture seams in Unity. In both meshes, the UV was mirrored, and they show a black seam at the middle of the mesh. I realize this is a mipmap issue, but both textures have padding on them. I already tried changing the wrap mode, though that didn't help.

Here's a look at the meshes and their textures:











Any ideas?

 

The background colour on your textures is black and the UV's are picking it up around the edges, some kind of bleeding effect. You should match the background colour with the dominating colour of your object(s).
