I have multiple BranchGroup objects in my tree. My objroot is associated with a MouseBehavior object, therefore all the BranchGroups objects can be picked by a mouse event, e.g. rotation. However, there are certain BranchGroup objects that I'd like NOT to be picked by the mouse. How do I do this? I tried calling "setPickable(false)" in my BranchGroup object, but it doesnot work. Worse, it gives me an error of Shape3D intersecting when I tried to rotate other objects.
