I fixed the UVs by moving the mirrored faces by 1 unit. No idea why this works though. They are basically outside the UV map. Every time I did this a new mirrored island had the same kinds of artifacts. Eventually I just did the same for all islands.
I still don’t understand hard edges though.
The Revolver is finished! I would really appreciate some feedback https://www.cgcookie.com/t/1403-could-use-some-feedback-on-this-revolver
