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

[Malcolm Pigott]

It's not the prerender camera that's not being drawn, it's the geometry under the Ortho2D camera - the "overlay".

When drawn "normally", i.e. with the scene node being the loadedModel, all is well.

However, when the loadedModel is a subgraph to the PRE_RENDER camera, the Ortho2D does not appear. It may well be being drawn, but isn't visible.
