How can i update the uv map after modifying the object? 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
