Well, finally someone made it. A true sky with povray.
Congratulations, looks perfect.

Great job, but shouldn't the clouds have thickness (I don't see any).
This scene easily shows the problem of sky_sphere, as this sky is a sphere.
POV's problem is that sky_sphere centers on the origin, but needs to center
far below the camera.

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.

It appears to center on the camera, wherever the camera is. This creates
the effect of clouds ramming into the horizon.

[looks out of window] Hmm, I can't see the tops of the clouds out there either.
I'd suggest you take a look at the source for this scene - the clouds are media
contained within the difference of two spheres, which makes for a fairly
adaptable technique...

Well, that's because you are under them...you can only see the top of
this kind of cloud if you are in an aircraft. (or spacecraft, I guess)
Otherwise, the top is obscured by...the bottom and sides. And these
clouds quite clearly have sides.

It only uses the direction of a ray, so you could say it "centers" on
wherever the ray started from. Its coloration is equivalent to that of a
unit-sphere centered on the origin, but it is just a background, not
centered anywhere.

Given the render time you reported I suspect you have background programs running, and
perhaps your render priority is set low. My
900Mhz Duron rendered the same image faster.
