Hi Robert I tried to setup the main view camera to rtt, and add a post-render camera (like in the HelpHandler), like you suggest. Then I added a screen quad to the post-render camera, which renders the texture of the rtt camera. It results in a black screen, it seems like either... - the main cameras textures are not yet available - the order of the cameras is wrong (although post render should be after main camera...) - i messed up something in my code (also probable)
I will try to make an example program that illustrates this behaviour...
