Help, someone.  I'm trying to make a scene of the inside of a church.  I
have light sources on the outside, behind some stained glass windows
(filter_all set to 1 for windows), and I have a light on the interior, just
for a little more illumination.  The stained glass pattern is showing up on
my floor, just like I expected.  However, when I add media, the place goes
black, even though the light inside has media_attenuation and
media_interaction turned off.  Does anyone have a GOOD tutorial on media,
describing what each variable does, in layman's terms?  thanks.  Oh, please
email any responses, if you can.

  Scattering media? Try specifying extinction .01 or so inside it.
