We specify the near & far planes manually and we don't have z-buffer issues with models on the earth's surface. Perhaps you should select the option DO_NOT_COMPUTE_NEAR_FAR for cull settings...

Once you add the surface geometry though, the near and far > planes are set such that the items are no long in the view frustum. If the surface geometry is in view but the calculated frustum doesn't contain it, then that sounds like a bug that should be investigated further. Are you certain the frustum really doesn't contain the surface geometry? It seems more likely that the problem is with z buffer precision due to the earth geometry pushing the far plane out so far that the surface geometry is getting buried, as other people in the thread have suggested. -- Bryan Thrall Principal Software Engineer FlightSafety International bryan.thr...@flightsafety.com _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.or g _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
