Overlap unwrapped texture with transparent image I'm working on a briefcase and want to make it look like a thread has been woven into it. However the only result I can get is based on the already unwrapped texture. How do I simply overlay, and create essentially another uv unwrap? See pictures for details and result im trying to achieve.

Setup


Texture for the leather


Result I'm trying to get


The problem, this happens when I texture paint 1 line on one side.
If I understand your problem, you want to create a second UV map because by now a single stroke creates multiple strokes on your texture. This can be done in the vertex tab, clicking the plus icon in the UV panel and re-unwrapping with the new UV selected. Don't forget to add an UV input node for every material you have, to indicate which UV map to use in that material and avoid unexpected projections.
