What is the correct way to create an independent prerender step in OSG?
I'd like to paint a skydome (from osgEphemeris) to the framebuffer which
doesn't affect the near/far clipping plane computation, the z-buffer,
scene lighting etc.
I've tried around using osg::Camera with PRE_RENDER as render order,
FRAME_BUFFER as rendertargetimplementation and (DEPTH_BUFFER |
COLOR_BUFFER) ss the clear color.
But it seems that this is not quite sufficient to make the prerender
step completely independent from the main render step.
What else do I need to set?
