Hi,
I have a problem. I have 2 virtual universes on 2 separate Canvas3D objects side by
side in 1 application window. I can access the canvases and scenegraph objects by
calling brainCanvas[0], objRoot[0] etc.
I want the two objects on the 2 seperate virtual universes to rotate at the same time,
when I try to rotate only 1 of them. Is there a way of doing this? I tried to add a
box to the second universe when the mouse was dragged in the first but it didn't work.
I have attached the behavior class and error message I recieved.
Thanks in advance
