Yet another of those stacked plane cloud methods!
On my website I've uploaded the code for the sky I'm using for my WIP desert
landscape image as seen in povray.binaries.images. I've gotten a request for
the code, and also saw a general request for stacked plane clouds here
recently.
My approach is not the most realistic maybe, but as it uses four planes
only, it renders very fast.
If you're interested, have a look at

Please let me know what you think. :)

You're missing the
global_settings{assumed_gamma 1}!
I never thought of you as THAT kind a guy! ;-)
Otherwise fine enough to use, but I'd say some more
comment on how and why would be useful for POVers
who want to actually know what you're doing.

Fast, yes, no too realistic, yes, but nice and good for beginners...

Looks fairly good for only 4 layers. And it looks quite a bit different
from the usual 1 layer texture clouds.
For me personally it usually does not matter that much whether the clouds
take 1 or 10 minutes to render...

I sure hope so.

That matters very much for me, especially in this case where I need it for
an animation.

Why? It looks awful when I use that setting.

Of course it does.
First set assumed_gamma 1 THEN code textures (and lights). You'll have to mentally
re-build all your assumptions on colors and finishes, but it's definitely worth it.
BTW very nice sky, esp. since you used only 4 planes.

Nah, there must be more to it than that, maybe display_gamma must be set or
something.
When simply using assumed_gamma 1, the results I get are wrong. A white
pigment in shadow, which should be 10% white looks more like 60% white,
which is way too bright. When I don't specify any assumed_gamma it looks
like 10% white as it should. My monitor gamma is about 2.2, which is the
default.

Thanks!

There is no complete shadow in your scene and with a light source of color
rgb 3 you should expect it being bright.

You seem to assume I'm talking about that cloud scene? I'm not. This is my
test scene:
// global_settings{assumed_gamma 1}
light_source {<1,2,-2>*100, rgb 1}
sphere {3*z, 1 pigment {rgb 1}}
