I couldn't do it with an OSG primitive, so I just jammed a glClear() into the drawable's draw implementation.

See Robert's reply. At that point you really need multiple cameras in order to manage the different depth zones. I think the osgdepthpartition example may be of interest to you too. -- Chris 'Xenon' Hanson, omo sanza lettere Xenon AlphaPixel.com PixelSense Landsat processing now available! http://www.alphapixel.com/demos/ "There is no Truth.
