and I want to make a lot !
but, the cloud is in a box with various density statements and if I move
my box, it is, of course, the same. If I move the box before adding
density, as I thought, it doesn't work (I have density pattern: boxed
and spherical).
How can I generate several clouds based on my basic one but with
variations in their "shape" ? (not sure if it is clear...)

It looks a bit like a whale.

Should be able to just rotate and translate along with some turbulence
changes too.
Move the entire object if you can.  Not sure how multiple medias would go if
all in the same container object, although the media statements should be
moveable as well.  The box pattern is a sort of singular instance I believe
so you could try using the keyword frequency and a number for it in the
density but I don't think that would work for your idea.

Well, you might get enough variation by rotating and scaling copies of your
cloud - could you union several clouds to get some variation?

However, a better suggestion would be to re-code your cloud code as a macro
with some randomness and/or params for variations.

Alternatively, take a look at Kevin Wampler's clouds in this group, and Mick
Hazlegroves derivations. I'm not sure if the code has been posted, but you
can find a varient of it in my irtc entry, "tmstormc".

BTW Nice cloud.

I will try the macro with parametric transformations and turbulences...to see
what's possible
thanks.

Translate density to same random location before applying
turbulence a after applying turbulence translate it back
to origin.
