I want to clear UV seams on a object and remake them myself, but neither UV Mapping > Clear Seams nor UV Mapping > Reset Seems to work. Please see attachment images.

This is my mesh before i do UV Mapping > Clear Seams:

Before clearing seams

This is my mesh after I did UV Mapping > Clear Seams. Seams still present:

After clear seams

How do I fix this problem? I can't clearly cut my mesh while those seams are around.

Here is the scene:

I think this model was originally created in 3Ds Max.

  • $\begingroup$ did you select the whole mesh in edit mode, then CTRL + E --> Clear seam? $\endgroup$

  • $\begingroup$ can you upload the blend model? $\endgroup$

    $\begingroup$ i downloaded your model but I didn't see seams, I saw only edges that are marked as sharp so the only thing you have to do to clear those CTRL + E --> Clear sharp. $\endgroup$

There were no seams in the model the edges were marked as sharp so the only thing you have to do to clear those Ctrl+ E > Clear Sharp.


This problem seems to appear more often when importing from another platform into Blender. I imported a mesh I made in Blender version 2.49 into Blender 2.68A, and had a similar problem: I had what appeared to be seams that would not clear with the CTRL + E shortcut. The solution was to use SHFT + E, and set the value of the crease to -1 on the numeric keypad.

  • $\begingroup$ Thanks for contribution brasshat, gladys found the solution. Those was not UV seams, it was sharp edges. $\endgroup$ Jun 24 '15 at 9:42
  • $\begingroup$ IvanKartofanov, when I started my answer I did not yet see your edit, nor the blend file. And yes, I agree that @gladys should change her comment to an answer. But I think my answer is enough different from hers to be desirable for completeness, particularly since more than on entity--seams, creases, &c. seem to have the same inconsistencies, especially between meshes created with pre-2.5 versions imported into post-2.5 UI. $\endgroup$
