[osg-users] osg::CameraNode doesn't render the scene behind the osgProducer::Camera

Thanks for the tip, but I can't use osgViewer, because I use custom
framework and this framework use osgProducer::Viewer. 
The Prerender Example in osg framework use also osgProducer::Camera and
osg::CameraNode to render the scene to the texture. Maybe the problem is in
the using of the screen aligned quad (=> I align the quad to the screen in
the vertex shader).

What do I think?  I'm confused.

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).
