Please find attached my code. Maybe I am doing something wrong.
The relevant file is "BackgroundCubemap.cpp".
As soon as I move the camera beyond the bbox of the shader geometry (camera
y>1.0) the background vanishes. It does not do this if I change the cullvisitor.

Do you mean in OSG? Please look into the .diff I attached to the original post.
It is:
Code:
if (_computeNearFar && bb.valid())
{
if (!updateCalculatedNearFar(matrix,*drawable,false)) continue;
}
If the whole drawable is behind the camera, updateCalculatedNearFar returns
false and continues without adding the drawable to the current render graph.

OSG 3.2.0, built from source.
Thank you for your trouble,
