Hi!
Im doing a dark alleyway scene, and im experimenting with media a bit...
http://img132.imageshack.us/img132/4606/alley2ru4.jpg
want these "clouds" that appear, probably as a result of the density
thing..
If you got any tips, please help me.
/rush
----------the media code-----------
media { // atmospheric media sample
intervals 10 //10
scattering { 1, 0.05 extinction 0.5 }
density {
bumps
frequency 2 // <- add this line
color_map {
[0.00 color Gray20]
[0.50 color Gray40]
[1.00 color Gray20]
}
}
samples 1, 10
confidence 0.9999
variance 1/1000
ratio 0.9 //0.9
}

Well... setting all the colors in the color map to the same did the trick...
Probably not the A+ way to do it, but who can tell on the outcome.. ;)

One thing that you can do, is to contain your media in some container. In your
case, a cone with the sumit slightly over the light and a bit larger than the
light's cone would probably do nice.
As a side bonus, it would render faster as the media will now only be computed
where it's visible.
cone{<0,10,0>,0,0,Light_radius+0.1//adjust dimentions and translate as needed
pigment{rgbt 1}//perfectly transparent
hollow//so it can contain the media. It's the only use of that keyword.
interior{Your_media}
}

Its not harder than that?!
Kewl! And rendering times _were_ getting outta hand...
Thanks!
