you have to set allow detach bit for the BranchGroup you want to detach. so you
have to set detach for the "scene"
from the java3D document:
>BranchGroup Field Summary
>static int ALLOW_DETACH
>For BranchGroup nodes, specifies that this BranchGroup allows detaching from
its parent.
so you need:
scene.setCapability(BranchGroup.ALLOW_DETACH );
Utku Er.
