I'm not sure what you're asking exactly but maybe this will help: In OpenGL, there is nothing special about GL_LIGHT0. However, osgViewer::Viewer by default uses GL_LIGHT0 as a headlight. You can change this behavior by setting the OSG_DEFAULT_LIGHTING environment variable (see 'osgviewer --help-env') or by calling setLightingMode() on your osgViewer::Viewer. Hope this helps! -- Bryan Thrall Principal Software Engineer FlightSafety International [email protected] _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
