How can I flip or re-position overlapping UV faces?

Hi,

Back yet again. I added seams to a model and got it to UV unwrap about 95% well, but some faces are overlapped. I found this:

<i>Unlink    Selection</i> ; AltL    Cuts    apart the selected UVs from the map. Only those UVs which belong to    fully selected faces

and other stuff to manipulate the UV map, but for some reason, ALT L does absolutely nothing when I selected an overlapping quad face.

Is there any way to flip it alone the shared edge? Make it so ALT L works? Any good strategies to fix this UV map?

Thanks,
Tim

Googled for Alt-L (which i’ve never used or heard before) - it brings 2 first links related to 2.6 and 2.4 wiki doc pages.
Functionality is when e.g. in UV editor there is Lasso (Ctrl-Left) vertex selection belonging to different faces and some faces are not selected fully, Alt-L drops selection of vertices which are in not fully selected faces. This works in 2.49.

2.6 does not have listed this in User pref keys (or i simply could not find this); it does not have this functionality either.
I suppose this is copy/paste effect in 2.6 docs.

Not counting that rounded parts of the mesh have excess geometry imho, selecting faces of one ‘leg’ or stright segment and using Follow Active quads could give better results if done one by one.

Thanks again eppo,

it’s ALMOST perfect, is there any way to cut and paste or otherwise manually edit the few overlapping faces manually?

I’d say select offending part and see if adding seam to separate it helps unwrap. It’s often just a trial and error what helps…
