Hi,

Thanks!

Yes, you're right. I made the clouds so thin firstly because of render-time
and secondly i had problems with thicker clouds getting too greyish like
some rainclouds.. Perhaps i can get the look right with different extinction-
values..

Yep, i'll try to make a flythrough in the next animation.

Very cool.  It's even neater that it's animatable.

Very impressive, good render time too.

I was thinking of doing a 'from orbit' picture of a skyhook descending to
it's docking station - your picture reminded me of the final stages of that
descent.

What are you going to do with it?

Thanks! I'm already rendering the next animation =)

Thanks! though i fear that the rendertime increases as the clouds get more
detailed
and higher res.

Yeah, that would be a possible use of it, but for greater distances, e.g from
space, one probably had to blend into an other method, i think.

> What are you going to do with it?
I plan to make the clouds look more realistic and detailed and to write a
macro around it for easier handling (like in Jaime Vives Piqueres' stsky.inc),
more different cloud-types (cirrus, stratus, cumulus) for simultaneous use,
improved atmosphere (best would be with physically correct color-gradients
for sunsets and such..) and support for sphere-shaped atmospheres for planets
(currently it's an endless plane).

Quite some work before me =) (This could take some time...)

At the moment the media-density pattern for the clouds and the right
absorbtion
and lighting gives me headaches.. hopefully i'll get it right soon.

If you do all that :-) I can wrap it up into a plug in for Moray.

Thats the reason why I posted the animation as mpeg, too.
Their content is equal.

Sure, i had planned to post it, but i first wanted to clear it up
a bit first and do some more research to make them more realistic.
But if you are interested i'll post the current version. i have to
add though, that my current Version doesn't look as good as the
anim in this post imho.
I'll post the source in p.b.s-f and my latest anim in p.b.a
