I could not get the hang off the unwrapping in 3DC for a long time… in the end I mastered it you just need to get use to it.
There could be some improvements alright, but it still works a treat. You just need to know what your doing with the tools you are doing it with:)) One thing I didn’t like about it was; when I was unwrapping models, say there was about nine parts to unwrap, as I got closer to the end of unwrapping the first parts of the meshes/unwraps were getting very blurry, making it a little harder to paint. I use UltimateUnwrap now, but still love 3DC to do my modeling;))
