I'd like to overlap UV map islands which use the exact same textures. Despite coming from almost symmetrical parts of the mesh, their shapes always differ slightly on the UV map so I cannot use scale/rotate/move to overlap them whole with 100% precision.
My current method is to roughly overlap the islands. Then separately select all vertex pairs between them and then in the UV context menu, align X and then again to align Y. But this is very time consuming. Is there a way to select all vertices and align them based on how close they are to each other ? Similarly to how you can merge vertices of a mesh by distance, but align instead of merging ?
