I am modifying a pre-made armor mesh. The armor has some holes in it that I would really like gone. So I deleted the faces with the holes and replaced them with new faces. The problem is that the UV map does not add the new faces, so the new faces are not being textured with the rest of the armor. I know I can unwrap the new section, then patch the UV map manually, but I would prefer a more automatic way since it would probably look a bit better.
I am pretty new to Blender and I am using an outdated version, but any advise would be greatly appreciated. Thank you.
