Im trying to do realistic skys i pretty musch have the atmsophere down , but for
the clouds i just wish i had multi-scattering. i tried two medias w/ the same
cloud texture in the same object. That didn't seem to work.
Im not in a big rush to get this but any help will be much apreaciated.

Scattering media assume that any ray interact at most once with the
material. Adding many media or density, as well as increasing the
density, don't change that assumption.
Using the version 3.7 beta, you can use the SSLT feature, but, here, you
have the opposite assumption: Each ray is assumed to interact a very
large number of times with the material.
Actualy, there is no middle ground. There is no model for more than 1
and less that 1000+ interactions.

thanks Alain but i dont think i can use sub-surface scattering with media but
thanks anyhow
