Robert, We've created our own event processing system. We need to manage a common scene with different node masks, switch node settings, etc. The problem is that the event traversal and update traversal happens for all views before the cull/draw traversal. So if we follow your methods of processing events in the event traversal or update traversal, we end up with all views looking like the most recently created view, instead of being unique. If I change the scene graph in the camera's final draw callback, it works but OSG spits out a bunch of OpenGL errors for what I'm assuming is the current frame. Thanks for your time.
