I am using Danny's uv tools to lay out the head of my barbarian chap for this months challenge.

I assigned the materials to the different groups of faces as per the tutorial and laid out the UVs, however I have noticed that on some of the shell the UV's on the right in the editor appear on the left of the model in the perspective view etc etc.

I tried selecting the shell of the bits that are backwards and flipping it over using poly flip UVs, but it says 'current selection does not match required selection type'. Should I be selecting something else?

Anyone got any ideas? I am a bit stuck as the bits that are not backwards don't match the bits that are. It was all going rather well too up until now....
