HI Suvajit, The debig message is telling you that it's just reusing the osgViewer::Scene object, not that it's not re-assigning the scene data itself. The Scene object is a background class used to manage multiple views sharing the same Scene.
As for the no visual changes, well are you calling frame afterwards? You won't see any changes unless you re-render the scene. Robert.
