Thanks Paul, I'll look into that. I was also wondering if it was possible to use kd tree to solve ordering problem, but not got round to investigating yet. I know there's code already in osg for dealing with bsp and kd trees, so, is there an easy way to use that code to solve my glass problem? Chris
