The node your remove from the scene graph is one you need to call releaseGLObjects on, it'll traverse down the subgraph below this node calling releaseGLObjects on all the StateSet and Drawables for you. > I use the model to create mutiple instance (use mutiple PAT) in the scene.

The other instances would have there GL objects released, so they'd have to recompile them, so there is a potential waste of operations, but functionally it should work.
