Hi Jesper, Anyone couldn't find your problem by this way, but problem looks like simple. I advice you to look at cOSG class and Render threads activation way in osgviewerMFC example. I think there is render thread activation problem. You can change clear color but can't render scene. So I think problem is threading activation.
I hope have answered your question. Best Regards. Umit Uzun 2008/9/25 Jesper D.
