Similar questions have been asked but i couldn't find one fitting my situation. So i've reshaped a boot model to be used with a new series of textures. Every single vertex has been moved. How do i correctly update the uv map? i've tried unwrapping the mesh again but it repositions the islands (in picture: left - original, right - unwrapped). how do i get it to respect the original layout or update the map without unwrapping? thank you enter image description here

  • $\begingroup$ You can bake all textures from old mesh to new UV map. Choose old mesh with right textures, select new mesh (adjusted) and bake textures in "from selected" mode. $\endgroup$ – Serge L Oct 28 '17 at 10:18

  • $\begingroup$ i did as instructed and all it got me was a black UV map screen with the same unchanged mapping layout. $\endgroup$ – Nikolay Oct 28 '17 at 18:01
  • $\begingroup$ It is hard to tell what is wrong without actual .blend file. Also this method is more suited for objects with similar shape, because baking depends on distance and it will go bad, if there is some inersecting geometry between meshes. $\endgroup$ – Serge L Oct 28 '17 at 18:45
