I've been wondering about this...
When I import a model that already has UVs for the purpose of editing and I get the message that it contains x number of "odd faces", what does that mean?
I searched through the PDF and it didn't turn up anything for that.
It says to use "Clean" in the load options and that fixes it, but it also says that they'll be green in the preview. I look at them and they look fine to me - I just don't get what's "odd" about them.
I thought maybe it meant ngons or otherwise bad polys or floating and unconnected vertices, but I don't see that either.

Googling is no help either. Google "odd faces" and I don't think they quite understand what I'm looking for.

"Odd faces" as you may have guessed isn't a technical term :-) Its either duplicate faces (i.e. two or more faces share the exact same vertex indexes), or non-manifold edges. There's a diagram here ...

UVLayout's "Clean" operation ties to fix these by deleting the duplicates and inserting new points where it finds non-manifold edges.

Thanks for the reply Phil.
I figured out what the problem was finally. I had mirrored an object on the X axis and it had polygons on the ends that I forgot to delete before mirroring, so it had coplanar polys on the inside.
