Hi Robert, I have already tried to call setUpRenderingSupport but without success.
I am only using one slave camera at a time. At application runtime the slave camera is removed and a new camera is created with a new graphic context. The reason for that is that I have integrated OSG into QT4 and when I embed the OSGQtWidget into a new parent window at runtime, the existing window- and HDC-handles are deleted by QT and new are created. So the current OpenGL context gets invalid as well. So I try to delete the old osg graphic context and slave camera as well and create a new graphic context and assign it to a new slave camera.

BTW, why are you creating/adding slaves on the fly? How many slaves do you have? Robert.

One idea might be that the OSG contextID is handled incorrectly at GraphicsWindowWin32 (I use a GraphicsWindow32 which is initialized with inheritedWindowData and setInheritedWindowPixelFormat) > > Thanks, > > Daniel > > _______________________________________________ > osg-users mailing list > [email protected] > http://openscenegraph.net/mailman/listinfo/osg-users > http://www.openscenegraph.org/ > _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/ _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
