HI Bob, If you are adding a scene to a viewer you should use viewer->setSceneData() so it can manage the internal osgViewer::Scene object as this manages DatabasePager correctly for your scene.
For in scene graph Camera's like RTT then use addChild, occassionally you also detach a slave Camera from using the viewer's scene data and in this instance you also use addChild. The osgdistortion example shows this in action. Robert.
