since the SSM creates some objects internally there is a sort of
sequence to maintain when using it and then manipulating
camera/viewport/foreground/background. The function that triggers the
creation is setRoot, so changing or using the above objects of the SSM
requires a call to setRoot first (I've used a dummy call with NULL as
argument in the past to work around this).
But your code already does the setRoot call first, so that is not the
problem here.

// Create Background
GradientBackgroundRefPtr gradBack = GradientBackground::create();
gradBack->addLine(Color3f(0.87f,0.85f,0.76f),0);
gradBack->addLine(Color3f(0.57f,0.54f,0.32f),5);
^^^^^
did you mean 0.5f? By default the GB takes normalized coordinates, i.e.
ones in [0,1] unless you call setNormPosition(false).
hm, according to my test run that is not the problem either...
What revision of OpenSG 2.0 are you using? A little while ago I fixed a
bug that left the wrong matrix stack active (r1850), that might be what
you are running into.
Cheers,
Carsten
