I thought of that too, but it seemed like overkill since all I needed was a bulk Z clear at the right time. Plus, I couldn't immediately describe to myself how the stencil buffer would accomplish this. Don't you still need to wipe the Z values in order for the Object B fragments to overwrite the Object A fragments (both of which have to be generated with Z write and Z test enabled to self-occlude properly)? > Robert. -- Chris 'Xenon' Hanson, omo sanza lettere Xenon AlphaPixel.com PixelSense Landsat processing now available! http://www.alphapixel.com/demos/ "There is no Truth.
