Try putting a BranchGroup called root in the simple
universe, then attaching your dynamic branchgroups to root, then using the
detach() method to remove the dynamic branch groups from root. Make sure
you set the capabilities of the nodes to allow detaching.

You don't have to stop the rendering to move your objects. If your
objects are being moved within behaviors that wake up on every frame (

way this is written it looks like you would be adding objTrans each time to the
