i hear ya pior, i miss it so much MOP- you could write/modified the script that duplicates the mesh then copys the attributes back over once its been imported, magic no data loss, pity max cant do this
nice find, it would be nice to see/ hear how the performance is because most peeling and unwrapping scripts in max are pretty slow with dense meshes. I highly assume that with the next max releases the UV editor will be redesigned with better performance and multiple unwrap algorithm types to choose from.
Yeah, RoadKill is good but it requires exporting to .obj's, which destroys data (and is fiddly). CrazyButchers script is the way to go! I'm curious to see how XRayUnwrap differs from the Blender LSCM code in actuality, but that link doesn't work on their page. Boo. Other than that 5 euros is practically free.
