Very interesting! Have you tried this?

No because If I want Rhino <--> Moi that is yet natively Inside Moi By Ctrtl + C, Ctrl + V on object(s) selected! ;)

If I want Free Rocket 3F <--> Moi that is yet existing in this prog! ;)

If I want other progs I take the time to make a classical Export / Import OBJ :)

And I suspect these scripts working only with the Polygons' World and not with the Nurbs' world...

i've tested between softimage & blender & zbrush (goz works better)
works perfectly but just for 1 object, more wont work
so for a scene or multi-object will be better to work the old fashion - save to a file
