about the mapping, the original addon from jesterking does have this,
i ended up not porting it, but can look to do it over the next month, should be straight forward but it’s the only period i’ve got time,
cheers
*a quick note, i just realized we’ve hijacking this thread that is about an entirely difference but quite usefull addon. maybe we should move this discussion to the original’s addon thread → Import Rhinoceros 3D files into Blender
