Okay okay,
i know, this item isn't so easy. I understand, how to get a media inside
the mediabox in moray to activate it. But how to create a media, that
simply shows the light beam of a spotlight? Tried a little bit with the
absorption and emission color, the scattering color, but it doesn't
work. Maybe, someone can help me a little bit. I'm desperate.

1) Make sure that the object you're putting it inside has the hollow tag 
set (the number of times I've forgotten that... Grr...

2) Create your texture with an interior.

3) Create a media 'object' from the interior RMB menu.

4) Activate the scattering property in the middle pane of the texture 
editor window.

5) Add a scattering colour from the RMB menu of the Media 'object'

6) Define the scattering colour.  RGB 0.15 works reasonably well.

7) Add a pigment->solid colour to the [Standard Texture]

8) define the solid colour as rgb 1.0 Trans 1.0

9) Assign the texture to the object.

10) Point the spotlight through the object, and up the multiplier of the 
spotlights colour (if you used .15 for your media, then x5 works fairly 
well.

11) render.

12) Curse when you realise you've forgotten to perform one of the steps.

I'll post a small .mdl to moray.binaries that I constructed whilst 
writing this reply, so you can have a look at it.

And if anybody want's to pick holes in my procedure, feel free, but it's 
just rendered the correct results for me now.  

Oh, and you'll almost certainly want to tweak the settings, then tweak 
them some more, etc. etc. etc.  :)

And if you want to define an atmospheric media, then in the texture 
editor, select the Media 'object' (the one you activated scattering in 
the central pane in) and rename it by either hitting Alt-Enter or 
selecting Properties/Rename off the RMB menu.

Hope this has been some sort of use.

Bye for now,
     Jamie.

Usually if you want scattering media showing light beams you will need to
lower the extinction value (to something like eg. 0.1). Then you can pump up
the density without getting just a dark, dense and impenetrable fog.
