Hi Michael, As Guy says the rendering back end is only doing an internal setup of first entry into osg::Camera, once the rendering back objects are cached they are reused. Setting this cache to NULL will trigger a new update.
Ideally the code should automatically do this though, implementing it will require adding a dirty mechnism to osg::Camera and the related code in src/osgUtil/RenderStage. Robert.
