Wish I had my camera with me when I went out to the store the day after I
last posted a reply here. The sunset was one of those beauts with plenty of
color. A very large blanket of clouds covered most of the sky and was only a
faint lavender color before the sun dropped below it, the air itself looking
lit by yellow sunlight, then it changed to purple with brilliant orange-reds
on the parts underneath. What made it interesting to me more than the colors
was how that single-layered cloud looked upside-down. It was as if it were
bubbling downward, with an appearance like cumulonimbus cloudtops jutting
out below and into the sunshine out of the ever-darker purple. Whole event
lasted maybe 10 minutes.

Anyway, yeah, if you could get clouds together with the background sky it'd
be a vast improvement.

In your pov script, which I tried again, I pointed the camera higher up
rather than straight ahead. Your sunrise/sunset times (4:30 and 19:30) has a
black sky overhead, fairly sharp boundry too. IRL it never does that, unless
perhaps while in a high altitude airplane.

Something to consider might be azimuth of sun position so that one side of
the sky has brighter colors than the opposite side. Just an additional
semi-transparent pigment layer overlaid the main sky color pigment could be
used for that. Looks like that could be added at the final skysphere using
the Az variable which Sunpos() macro returns.
