Hi Hannes,
can't see anything obvious.... Can you try to switch on
debugging mode? And you are sure you got the ogl context?
To switch on the OpenSG debugging messages:
#include <OpenSG/OSGLog.h>
OSG::osgLog().setLogLevel(OSG::LOG_DEBUG);
OSG::osgLog().setLogFile( "osglog.txt" );
and see if the output gives you any clue...
Regards,
Toni
