@Losticmate :
I have already painted over edges (read previous posts) , and it does nothing , it seems to be an UV problem or mirroring !!


@Ventilator :
Thanks alot for the script !
I've tested it, but the bleeding wasn't correct everywhere ; in some edges it bleeds the background an not texture.
The problems remains , even if i bleed the texture manually.
Yes the problem , must be the mirror , but i've used Blender Mirroring ??

If i switch Mipmapping ; OK in front , but in the back there is always white seams

Well i'll retry to work on the mesh to see if i can do something !
