Hi Noah, I'm not familiar with the tutorial, so there's too many unknowns for me to guess exactly what is being done wrong - there must be some update order issue but beyond this I'm afraid you'll need work it out yourself, or post code.

Thanks, I got this working. There is another issue I am having with this though. The matrix manipulator is set up to follow a PositionAttitudeTransform (PAT). It uses a TransformAccumulator and a followNodeMatrixManipulator to do this as per the NPS 11.1 tutorial. Later in the code I move the PositionAttitudeTransform around and the camera follows it normally. The problem is that there is a lot of jitter in the camera, as if sometimes the camera position is updated before the PAT it is following, and sometimes afterwards. Is there a way to ensure synchronization?

Also what viewer library are you using? osgProducer::Viewer by default uses KeySwitchMatrixManipulator, and you select which manipulator using the osgProducer::Viewer API: void selectCameraManipulator(unsigned int no); bool selectCameraManipulatorByName( const std::string &name ); Or just directly via the KeySwitchMatrixManupulators's method: void selectMatrixManipulator(unsigned int num); In SVN the osgViewer::Viewer class does use KeySwitchMatrixManipulator by default, but if you can register one as the CameranManipulator, the osgviewer example shows how to do this.
