I just asked the same question to Support, but that I would ask here also. Ticket ID - 44863. I did find that you can do a control-c and control-v and copy a complete world in the menu editor. I do believe this is new for BETA5. Well anyway thanks for anyone that might know the answer. Brad
@fredi that copies it within the same world. I want to move it to another world. Thanks for your input.
I guess I can answer my question. hit control c on the node and control v in the next world. It does not copy the background. Very cool.
Background objects are associated with the world, not the scene. So in case anyone is wondering this is as it should be.
