Why two passes? What is the difference between that and just putting the HDR
image directly onto a sphere?

Sorry. My faulty explanation. What I mean is that I first rendered a large
(3200x1600) image with a spherical camera with only the media sky (took
between 24 and 48 hours). That image was then projected on a sphere with the
landscape which rendered in about 15 minutes, radiosity included.

This sort of thing would make for a great dual-monitor background if it was
rendered 2560x1024. :-)

I'll put it down to having a bad cold and reading what I wanted to read :(
Your explanation was good but it got twisted in my mind.

Ah, too bad it's a commercial program. I was excited for a moment :(

I think it looks like a painting because it has some
odd graininess to it, like the dark speckles. Also, the
ripples are a bit reminiscent to brush effects.
Is there a light source or just HDR and radiosity?

There is a light source (Sun) to make shadows more marked. With only the sky
and radiosity, the landscape is too washed out, so additionally, a black
screen is present behind the camera to block some of the luminosity coming
from the hidden part of the scene.
The dark speckle probably originate with low radiosity settings (testing).
Probably, in the final version, a finer aa will be necessary.

True. I think the effect could be obtained by other means too, for instance
with a high-resolution greyscale map drawn in a paint program. And surely
with the help of some functions? I am not good at that, but I can
imagine....
