I am new to blender, when i try to uv unwrap my mesh, blender hangs and become unresponsive. the mesh has nearly 35000 faces. it is a subdivided sphere which i used for sculpting. when i uv unwrap a simple cube , it works fine. is there a workaround for this, or a better alternative way to apply texture?

  • $\begingroup$ Which option are you using to unwrap your mesh? $\endgroup$ – Denis Mar 30 '15 at 5:30
  • $\begingroup$ i used both the normal unwrap and sphere unwrap $\endgroup$ – vikrant Mar 30 '15 at 5:32
  • $\begingroup$ i have also increased the TdrDelay of the graphics card to 10, but it still becomes very slow. is this problem only limited to me? can you do uv unwrapping for large models in blender? $\endgroup$ – vikrant Mar 30 '15 at 5:37

    $\begingroup$ While blender is processing the interface will freeze up. Try giving it a few minutes. Or subdivide after unwrapping. $\endgroup$ – gandalf3 Mar 30 '15 at 5:42

    $\begingroup$ That may be dependent on your computer configuration or blender version. $\endgroup$ – Denis Mar 30 '15 at 5:42

Potential Solution: Smart UV Project

Although I've never tested this method on a UV Unwrap task that has crashed Blender, I've found that using the 'Smart UV Project' option is much faster using the normal 'Unwrap' function.

I found this when unwrapping the mesh of an ANT Landscape body, where it would take several unresponsive seconds before Blender processed the unwrap using the regular unwrap function. However, when I unwrapped again using the 'Smart UV Project' option (with the default parameters), it was almost almost instantaneous.

I know this is a pretty old post but I'll leave this here just in case anyone finds it and gets help from this answer. (Hope I haven't broken any community forums by 're-opening' an 'archived' thread.)
