Hi,
I uploaded the movie of the unfold process.(Request Quick Time 7. H.264 format)

It is not understood whether this way is perfect.
But, I'm happy if this is your help.
Hexagon 2 has a lot of bugs. However, the Unfold tool and Paint tool are great and convenient! They work well in above all.
Unfortunately, I cannot yet export the good quality displacement maps....(I'm on Mac)
Thanks,
