Hi, I see you have an ATI card. If you crank up the OSG notify level to INFO, do you see any messages about difficulties building the GLSL shaders? My own ATI Mobility 9600 apparently has trouble with the user clip planes in osgEphemeris' shaders, which messes up the rendering. just a thought -- mew
