Maybe what I'll write is not relevant here... but I think there is something more general in the locking of the "export object" function in Vue Pro : Having experienced a HD crash, I had lost a 3d mesh original file... as I still had a vue4 scene in which the object was used, I tried to export it with VuePro : it read "Export forbidden" I found it strange as it was MY own creation... I believe that E-on kept on the 'safe' side, forbidding export of any obj that comes from old files...
