Hi everyone,
does anyone knows where I can find any good scattering media tutorial?
I've been trying to model scattering media, but I've only succeeded in doing
so with very large objects..
Is there any way to increase the "density" (not referring to the density
keyword) of the media so that I can use small objects?
Thanks,
Pedro

Just increase the scattering color. I guess it's quite linearly related to
the object size (didn't check, just a guess).
If scattering{1,1} works for your big object
scattering{1,10} should work for a object 1/10 smaller.

The density and color are the same value. It took me a while to get
this...brighter colors make denser media. If you have a density
specified, the media color and density color are multiplied together to
get a final result, so you can use one as a density control and the
other for color. I often find it useful to multiply the color vector by
a scaling value to get independant control over density and color, for
example:
emission < 1, 0.4, 0.3>*0.25
