glScissor is not positional state so doesn't have the same restrictions as clip planes so it would be the better tools to use.

Hmmm, Had a brief look in the osgexamples for this kind of thing and didn't get a clear example of how to do this, but I'll keep researching (bit new to osg being an old school Performer programmer!) Another option I just though about is to use glScissor rather than clipplanes as all the stuff I'm clipping is in a 2d overlay, am I going to run into the same issue with glScissor as with glClipplanes in that they are defined per RenderStage? thanks Nigel _______________________________________________ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
