I have the problem that when I want to paint in the uvmap window with paint, I get
all these seams together, it would not be when I used save uvmap layout I guess, but
to do it quickly it is not so easy. Everything that has been unwrapped is then visible
like a seam.
Oh gosh, I think you should redo your UV map. Liek srsly. But I’m not sure why there are those seams there, they aren’t visible in texture paint mode for me.
