UV island = Smoothing group?
Hi I'm quite confused about this concept.
I've seen that some people doesn't follow at all the smoothing groups in their workflow, when they are doing the unwrap.
I know that for instance UDK convert any UV island in a smoothing group.
So in the case of rectangular objects, some people use to put smoothing groups to get better normal maps, but when they unwrap they join what supposedly had to be separated because they are different smoothing groups..
I guess this is useful then for avoiding seams when texturing.
But wouldn't this unwrap change the smoothing groups after when importing in UDK?
