Hello Everybody,
I think for myself Unfold3D is currently the best UV tool.
Of course last versions crashed sometimes, with big meshes, or complex ones.
But now, all these problems have been corrected.
With the latest version, you get very good UVs.
No need to rework the UVs by hand.
And with the surface adjustement feature you can reduce stretching pretty easely !
I suggest you to try a demo.
