media_attenuation will have little effect with such a low-density media 
except to slow it down. That feature controls the attenuation of light 
passing through the media, which will probably be unnoticeable. The most 
likely problem is that you don't have enough samples, there aren't 
enough to pick up the shadows. Or they may just not be very visible with 
the settings and angles you have.
