All, Why is it that osg::Fog, and maybe glFog(), work as expected in RTT setups if FRAME_BUFFER_OBJECT is chosen as the RenderTargetImplementation on your Camera, but if PIXEL_BUFFER/_RTT are chosen, you must re-load the scene?
I think that people are under the impression that when GLSL shaders are used, glFog is broken, but that's not true. I think that if the osg::Fog is applied ( with Fog options ) to the Scene before setSceneData() is called, you will get fog, even in PIXEL_BUFFER type setups. BTW I have a GeForce 6 series on my box.
