Ok, so I have split up the mesh, and TRYING to get the seams correct, not to mention mirrored, for my custom body. It uses SL/Linden Lab UVs, just like any Omega based body.
Unfortunately, this process is very tedious, and I can't even get passable results, let alone good or perfect results. Trying to match up the middle of the back by splitting up the mesh. It's a lot of clumsy trial and error, and I was wondering if someone had any idea of an easier way.
