Enclosed you will find an object bad mesh. I was unable to apply any kind of primitive UV mapping projection. For example, if I apply spherical UV-mapping, later when I go out UVEditor, it shows in render mode the broken projection. I try a different method but with no success. While waiting for a fix in the UVEditor, I need somehow to workaround. Probably the broken mesh is not helping. I try to repair it but with no success.
