I need a non-uniform fog and I've tryied with this:
box{
<-100,-10,1>, <100,20,2000>
hollow
pigment {rgbt <0,0,0,1>}
interior {
media {
intervals 1
samples 1,1
emission <0.8,0.8,0.8>
density{bozo}
}
}
}
the result is a strange and innatural fog!
How can I do?

What do you expect with those settings?

One problem is the color. From the documentation (section 3.5.11.4):
"The bozo pattern has a default color_map built in that results in a
green, blue, red and white pattern with sharp transitions."
If you don't want such colorful fog, see section 3.6.2.3.2, "Density
with color_map."
Hope this helps.

To few samples. You probamly need something like 20 to 100 or more. Only use one
value, the second
is not used with the default sampling method. The default method needs AT LEAST 3
samples.
Try using the bumps pattern instead of bozo. bozo use it's own color_map, bumps don't.
