Hi Fabian, I'm afraid you don't really say enough about the specifics of your setup for others to know enough to help you.
With your View, do they are share the same GaphicsWindow? How do you setup the pre render step? A slave Camera? A Camera in the scene graph, how do you grab the live Camera stream? What version of the OSG, OS and hardware are you using? Robert.
