Hi, I have an application where I setup a "normal" osgViewer view with setUpViewOnSingleScreen(). This works fine.
I also create an FBO camera to which I add my scene. When I want to take a screenshot of the application I call osgviewer->setSceneData(myFBOCamera) and render via osgviewer->eventTraversal() / updateTraversal() / renderingTraversals(). After I get the screenshot I restore my normal scene with osgviewer->setSceneData(mySceneData). This also works fine for taking screenshots. What I want to do now is to turn off the "main" camera whilst I render the FBO (ie if I create a lot of screenshots for a movie I don't want to render to the screen). How can I turn off the main camera and render only to the FBO? I've tried calling osgviewer->setCamera(NULL) without sucess. Indeed when I meddle with the main camera I dont get a valid image from my FBO. I think this makes sense as the FBO is under the main camera(?). I also tried calling osgviewer->setCamera(myFBO) but no luck that way either. I also can't restore the original camera to the osgviewer. Perhaps I am solving the problem the wrong way - is there a better method? Perhaps having two seperate osgViewer objects? But then I think I have only one conceptual "View" (my FBO always shows the same view as the main camera, it's only a question of if the main camera should render an image or not), so having one Viewer, one View and two Cameras feels correct - it's just that it doesn't work :-) Thank you!
