HI Ricky, Your approach sounds correct. You are correct in that the user doesn't need to explicitly for the release of GL objects as the OSG will pass the GL objects across to the OSG's internal object cache to be release by automatically by the draw thread. Reuse of GL objects will also happen automatically for you.
