And I will love to share that, Paolo. Not much to it at all. In fact, it's
probably way too simple for a good rendering. Is a WIP, of course.
I tried to get better cloud colors by using a gradient pattern on a plane
between them and the sunlight so it would look like it gets brighter toward
the horizon. I rendered this part alone before giving it to you and I added
the "air" because it wasn't dark enough without that. The camera needed to
be in this, too, or else it might be trouble to get looking right again.
