[osg-users] Using Ortho2D projection camera under OpenSceneGraph PRE_RENDER camera

[Robert Osfield]

Hi Malcom,

Does your PRE_RENDER Camera not render to a texture that you attached
to it?  When you render to a texture the texture becomes the frame
buffer for the rendering of that cameras subgraph, there will be no
output to the main frame buffer.
