I think that the light 0 is used as a skylight/headlight attached to the camera. So if you want to use that light, you have to turn the default light off. > I dont have any lights other then mSun, but i see that in the code > osgEphemeris is used.

OpenGL defines up to 8 user definable lights. Unless you set something up yourself, you get only the default skylight/headlight created by OSG, nothing else. In plain OpenGL you would have no lights at all (ergo totally dark scene). So you need to define your own lighting rig if you want the scene to be lit.
