Delete UVs removes UV texture coordinates from the selected face(s). When you select a face on the mesh that has an assigned texture and delete the UVs, the assigned texture doesn’t appear any longer on the face(s) where the UVs were deleted. You can re-create the UVs for the selected faces (or the entire mesh) using the UV projection mapping operations.

Deleting UVs removes only the UV texture coordinate data on the mesh and does not affect the vertices on the mesh.

To delete UV texture coordinates for a selected face

1. In the scene view, select the face(s) for which you want to delete the UVs.

   

2. Select Edit UVs > Delete UVs. (If you are working in the UV Texture Editor you can select Polygons > Delete UVs.)

   The UVs associated with the selected face(s) are deleted.

   

Because the selected faces have no UVs, textures cannot be applied to them until UVs are re-created.
