I do. They aren't towering stratocumolus, but they obviously have
thickness. They have leading edges that are brightly lit, and darker
bodies and edges away from the light. I've seen clouds like this many,
many times, they are more common then the thunderhead type.

This isn't a sky_sphere. If the author used the technique I used in the
POV 3.5 demo file, it tries to simulate the actual atmosphere, with
shells of air and clouds centered far below the origin. It looks like he
did a lot better at it then I did, though... ;-)

The sky_sphere feature doesn't "center" anywhere. It is not an object,
it is just a background feature. And it can't do effects like this, just
pigments.
