I have now tracked down the inconsitency to osgUtil::SceneView not passing on changes the GL_LIGHTING mode when the LightingMode is toggled on/off. I've now fixed this and checked it into svn/trunk. This fix, will mean that in your example both with and without the slave Camera will behave the same, both won't have GL_LIGHTING mode enabled - which is exactly what you've told the viewer to do, and since the scene graph doesn't explictly enable GL_LIGHTING then this mode remains off, so no OpenGL lighting is enabled. To enable it you simple enable it manually in the scene graph, since you are managing your lighting in the scene graph then it makes perfect sense that you you be enabling the GL_LIGHTING mode for the subgraphs that require OpenGL lighting.
