- damn shlick, so with all of those WTF does schlick do, did some tests..

- google schlick see what you get, I got female masturbation

schlick phase
scatttering direction:

-0.3 -0.5 -0.8 -0.9 +0.55
...so, in this case the - 0.5 seems to look the best..

from http://render.otoy.com/forum/viewtopic.php?f=21&t=9380
"The phase function controls in what direction light gets scattered. There is currently one kind of phase function defined,
with one parameter, scattering_direction. If set to 0.0, it means light gets scattered the same amount in any direction. A
setting larger than 0.0 means forward scattering, the larger the value, the more light is scattered in a similar direction as
it was traveling. 1.0 means it doesn't change direction. A negative value means backscattering, so more light is scattered
back to where it came from. This makes objects appear brighter on the side where the light is coming from."

Very nice this will help with a current project. Do you mind sharing the node info and steps.

most of the standard volumetric setups from the forum, ies light in front of a specular sphere, all inside a specular cube, with camera outside of it, with scattering to full, with PMC set to 6.. the schlich phase gives it a more "foggy" look around the objets.. the thing doesnt really clear up all that well, maybe if it's very subtle ..
