I think I might be having a related problem. I have recently updgraded from OSG1.2 to 2.1.1. In my old app, I had a node inherited from Camera, loosely based on the osgDepthPartition example, which worked as a parent for skyboxes/spheres. It used to:
1) prevent its children from participating in the znear/zfar auto-calculation, thanks to this->setCullingMode(DO_NOT_COMPUTE_NEAR_FAR) 2) force its projection matrix to a fixed value within an overloaded traverse() 3) include osg::Depth to always draw at screen z=1 Under this would be a transform (like the ObserverCentredTransform in osghangglide) to keep any skysphere centred on the observer, and underneath that would be a sphere/box. This worked great under OSG1.2 and earlier; it made sure that skyspheres/boxes were always visible, were always at screen z=1, and were never clipped by znear/zfar autocalculation. Unfortunately, now it certainly isn't working - in particular, it now clips, and also is no longer drawing at screen z=1, despite the osg::Depth call. Has something fundamental changed concerning osg::Cameras in their migration from osg::CameraNode? Any direction would be useful. David
