Is there a way to "flip" a UV map? I have a cylinder I tried to put a logo on each end of. My first attempt was to simply use a Planar UV map and map the two end polys along "Z". The image-mapped logo showed up fine on one end but reversed on the other end. Eventually I figured out that the UV mapping was happening toward the +Z vector for both polys, even though the normals were facing in opposite directions.

I then spent about half a (frustrating) hour trying to figure out how to "flip" the UV map for the second poly without affecting the actual geometry. Simply hitting "f" didn't do it. Finally I figured out:

1) Make UV map for only the first end.
2) Rotate the entire object 180 degrees and make new UV map for the second end, which is now facing in the "correct" direction.
3) Rotate entire object back to original position.

That worked, but it's still an awkward solution - does anybody have a better one?

There's a button to Flip UVs. When you run it you can flip U, V or both.

FlipUV works best if mesh is unwelded.
