Hi Bruno!

I have to say, these are awesome clouds. If I can get my cumulus looking
half as good as this... :) Most of these images appear to have clouds as
continuous layers - are these isosurface clouds? And I notice there are
some 'fringing' glows when the sun is behind the clouds - does this
behaviour occur naturally when you move the light source or does it require
different media?

I'm not sure I understand what you mean by this... do you mean to use either
one or the other?

Yes, I'd rather not have used emission, but it did make a big difference. As
to reality - well, the effect I'm looking for would have to be simulated by
media interacting with itself via radiosity, which I don't believe is
possible.

Not via the web interface. With a newsreader, I believe so.

I'd like to see that when you have some results!
