I don’t know your experience with it, but I never use minimize stretch, because the result is always worst than the one I have at the first time.
So the only thing I can do is use the pin tool with live unwrap activated, but not always you can get what you want, and you need to do a lot of manual tweakings, adding more and more stretching…
I also tried UV sculpt pressing shift for smoothing with no luck either.
In other programs I know, like 3d max, the relax tool works really well, with a few tweakings.
Is there any alternative in blender to the Minimize Stretch tool?
Does someone really has any good experience with it?
