Hi there andreas and all osg users:

After some struggling setting up scene with
stereo, shadows and cluster alltoghether,
I have still a little problem:

While my indoor scene seen from the inside looks correct,
with nice smooth shadows, if I look at it from on top the 
ceiling, I have noticed that the shadows casted from the main
light are visible in "transparece". How is that possible?

I attach a screenshot of my scene with the point of view 
a little higher than the ceiling. I'd expect to see a flat white 
surface...

tahnks
E.
