Hi Robert, I solved my problem by flipping the scene upside-down for the prerendering. It has some limitations so I keep your suggestion in mind.

Hi Brede, You effects like this I tend to have a custom Node that manages a set of internal Camera that it updates then traverses. The osgShadow::ShadowMap and osgSim::OverlayNode are examples of this. Using the approach allows you to manage multiple cameras and multiple threading easily. Robert.
