Hi Stephan One other note on getting FBO rtt to work. Seems you have to wait for the uiview to be launched before the context is actually ready. At the moment I'm doing this by attaching the rtt camera to the graph after the first call to update, but i'm guessing this would be very device and frame rate specific. I currently have my timer set at around 30 fps.
I think I might be able to move the call to createframebuffers in the iphone viewer to happen during realize rather then waiting for the view itself to be displayed. But i'm unsure if it is framebuffer or context related at this time.
