Thank you Gergely for your quick respond!
It is strage. When I call a macro I can replace the macro parameter to a new one, but the hotspots cannot replace these parameters? I want to use this OBJ1 multiple times in OBJ2 so I can edit all the separate OBJ1 parameters with their own separate Graphical Hotspots in 3D. It is working without graphical hotspot.
