Thanks Sergey, that was what I feared.
It will not be easy to get these rendertarget parameters at the nested
camera level.
I have searched for a way to 'copy' the render target from a camera in
parent nodepath, but the Camera class does not seem to be taylored for
that,
I will probably use a visitor to propagate RTT parameters to nested
cameras.

Same as usual, render to framebuffer by default.

Yes, you should specify rendertarget if you dont want to get result on
framebuffer.
You should explicitly attach same rtt to both your cameras.

Hi everybody,
I'm stuck with a problem when trying to render to RTT camera.
I want to render a scene to a RTT camera (the way osgposter does it).
In my scene, I've got a osgephemeris SkyNode.
To avoid culling problems, the skynode is rendered with it's own Camera
( see : http://osdir.com/ml/OpenSceneGraph-Users/2009-04/msg01170.html the
suggestion of J-S Guay)
While rendering directly to frame buffer my scene is ok : scene + skydome
While rendering to a RTT camera, the objects below the Skydome camera are
not rendered in the texture.
I've tried to play with different parameters (render order etc...) but I
don't understand how it work (or should work).
During the traversal of a scene rendered through a RTT camera, how the
nested cameras behave ?
Do they automatically acquire the RTT camera target ? Do I have to set up
something ?
