Hi Roger, You make no mention of how you are creating/reading your tree models. Are they all they all separate trees models loaded form disk? One tree that is instanced many times?
How you manage things depends upon how you've created the models. The OSG allows share of state, and there is even a visitor in the osgUtil::Optimizer that seeks out duplicate state and removes it so try using the Optimizer. Robert.
