Re: [osg-users] osg::CameraNode doesn't render the scene behind the osgProducer::Camera
Thanks, you are right the problem was setup config: The one corner of screen aligned quad is in the world center, I used vertex shader from rendermonkey to assign the quad to the screen. After I placed the quad corners to another coordinates, the problem was away.

[osg-users] osg::CameraNode doesn't render the scene behind the osgProducer::Camera
Hello, I use osg::CameraNode to render the scene to a texture, and then I display this texture on the screen aligned quad. Problem: If I fly throw the scene, osg::CameraNode don't display anything. 1) The osg::CameraNode clips the scene and this is the reason, why it doesn't display anything 2) osg::CameraNode has position and the osgProducer::Camera clips the osg::CameraNode, because osg::CameraNode is behind the osgProducer::CameraNode. What do you think? What can it be? ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

BTW, try updating to 2.x and use osgViewer rather than osgProducer, it might not directly solve your problem but it should clear up some of the confusion over different camera classes as there is just one - osg::Camera ( what was called CameraNode).
