New to the forums and I have a pretty general question regarding the UV images blender saves out and can't seem to find an answer anywhere. The below image shows the edge of two faces. I'm wondering how you know which face the lines belong to. It seems pretty random.
Basically what I'm trying to figure out is if I go into photoshop and try to only select one face to paint onto, which lines do I also select so that I don't have black edges on the mesh?
I hope that's clear enough. If not I'll try to reword it.
