Hi there i have a meshmodel of a Body from some Vendor, there are two little faces missing. Im pretty new in blender i got it to add the missing faces but how can i bring them in the existing UV-Map? for example to later be able to paint on them?
If it’s just a few missing faces, and the edges are clearly defined, you could just select them on the model, unwrap them specifically, then stitch them into the existing UV map.
Oki’s post does a good job of explaining the stitch process. Alternately, you can rightclick inside the UV editor window when in edge select mode, and choose stitch there.
Getting the missing faces in is even easier. Simply select those faces on your model, hit the U key, and unwrap them. They’ll end up being massive and totally out of scale in the UV editor, but all you need to do to fix that is shrink them down to their roughly appropriate scale, then stitch them in. The stitch process itself should fix any other scaling issues.
It should just snap right in during the stitch. If you’re left with any overlapping faces, then grab the other two edges, and snap them together as well.
