Thanks, I ended going with a dual cull callback solution. I attach a callback to the node that records the last frame number it was visible. I then attach another cull callback above the camera that culls if the last recorded frame number of the node is less than the current traversal frame number. This works really well, as long as the camera is traversed after the node in the scene graph. Cheers, Farshid
