Orca3D losing material assignments

I haven’t seen too much mentioned here on the use of Orca3D but wonder why it is that is I assign Orca materials for a weight and balance report from Orca and then export or copy/paste those solids to a new Rhino instance, they lose any Orca materials and will not generate a valid report. I’m not saving small which would seem to dump any Orca attributes and it seems that those Orca material assignments even survive an AutoSave! I’m going to take this up with Bruce at Orca but wondering if anyone here is seeing the same issue.
