Careful. This not something you can assume so easily. Many of the early MRT-supporting implementations only support the same number of bits on all RT's. (The 7900 is a rather old card, so my guess that it does _not_ support different bit-depths when doing MRT rendering... Look it up on the internet) > I'm sorry when I ask a stupid question, but I have never rendered twice > in OpenSG before. > Maybe you know an example how to do that? You add two ViewPorts on the same Window, where the first has a GrabTextureForeground (or is a FBOViewport, which is faster). You can then use the grabbed texture in the second viewport's scene.
