Hi Frederic, Are you familiar with the osgViewer/osg::Camera RTT capabilities? They are very flexible now, you can render subgraphs under an scene graph RTT osg::Camera as a pre rendering stage then switch it off for subsequent frames. Have a look at the osgprerender, osgprerendercubemap examples as well as osgShadow itself.
