Like many people I try these sky pictures off and on and with the recent ones
being done I've tried again. Top render was fine for the sky I thought but then
I went and had to try and improve upon it and forgot to save the original script
as it first was. With luck I'll find the correct settings again I hope.
There's not that much to it, only two patterns on a sphere based upon Chris
Huff's scene.
It also has non-parallel sunbeams, another reason for making changes; which is
how I ended up with the bottom render. I mucked it up pretty good I think, but
hey, look at those 'parallel' beams thanks to MegaPov. I couldn't get parallel
sun-beams with a point light source the first time and wondered why the first
picture didn't look right. So the second render uses a spotlight (says in the
doc it can be done with point lights too?). Never mind the rainbow, it isn't in
a realistic position, there for looks.
The ground became a height field which helped it a lot, but the water and sky
suffered. I never get completely good renders done!
It could be wetlands or river delta but I'd have to spend much more time on it,
so later maybe.
Thanks Lewis and Chris for motivating me to do something like this again anyhow.

Hi Bob!
The first one is definitely better!!!
The rays doesn't need to be parallel. After the discussion here when
Mick published his cloudy pic I looked for references and found that he
had been right.
Keep one going ... this one sure has class.

I think that this "phenomenon" is called 'crepuscular rays' (not really a
phenomenon, but you know what I mean)

Hey,
about the physics, it just looks better.
Go on, i think i will never be able to look media like this ...

The first one (non-parallel rays) looks much better. The reason for my opinion on
this is that even though they look non-parallel, they could, in fact, be parallel.
The camera angle might give the impression of non-parallel rays, such as are seen in
real life. Nice media :)

The non-parallel one looks more realistic, anyway,
at least for the sun's apparent position.

Excellent!!! the rays shouldn't be parallel anyway. Definitely would like to
know how you achieved this.
Keep up the good work.

In fact the rays coming through the clouds in reality _are_ parallel.
But they don't look like that because of the perspective. This should
be possible to model in POV, too.
