As requested, here are my atmospheric media settings... Ken I am
posting this in here because it is only a snippit of code and I believe
it belongs here as a reply to Gail's request.
As a side note, I upped the intervals and samples because when two or
more spotlight beams overlapped there was grainyness which isn't
entirely gone, but is diminished. Also, extinction is a good value to
play with.
Steve
media {
intervals 35
samples 10,50
scattering {
1 , rgb <0.25, 0.25, 0.25> // isotropic scattering
extinction 0.1
}
}

Thanks very much.
I'll see how this turns out.

Actually, I changed the scatter values to around .15 which gave an image
much more like the original (except that I tinted the light brownish) to
try and give a more dusty feeling...it looked better with white light,
but this light looks more like "sunlight") Anyhow, the image is
1152x864 so I'm not posting it, but rest assured that my results are
much more in line with my original.

Well, I couldn't stay away from the image, so I decided to try using a
density pattern to get the feel of floating dust....well, I wasn't
entirely successful, and the cost for this experiment was around 10
hours of reduced system performance. (Lessons from this being "Density
takes a LOT longer") But I've shrunk the image to 800x600 and decided to
post it. I have a few ideas on how to make it look better (make the
falloff greater to increase the fade near the edges) increase both the
verticle and horizontal scaling of the granite pattern I used (or use a
density map) Also I think better textures, more complete crates would
really add to this image (ie making the crates out of slats rather than
boxes). Any other suggestions would be greatly appreciated.

Don't know if scaling the granite will do the trick? The dust in the beam looks
to "cloudy". Maybe take the media from your first pic, make it less dense so you
just see it. Then add a patch of dust here and there in the beams. A little bit
more near the floor and less near the ceiling.
If you stick to scaling the granite, try a non uniform scaling so you get a
feeling of horizontal layers.

The boxes are ok.
The contrast of the picture does not feel right, the floor is to gray and the
far away background is not black. High ambient?
Do you want to keep it pure B&W? I'd suggest a very little bit of colour
contrast, something like gray+0.05 blue for the floor and pillars and white-0.05
blue for the light. It's important that you don't see that there is colour in
it, but only feel it.
Radiosity would be good here, but you'll have to use the slooow non-contained
media.
Just my ideas, it's your picture, I like it and am looking forward to what it
wil become.

Is it a bug that's causing the great steps in the shadows of the columns? I can see
nothing in the modelling that would acount for them?

This is really coming along nicely. Can't help thinking X-files
when I see a spotlight or torch light looking like this. They
must have had really expensive smoke machines and torches in the
X-files studios, because the used them in every episode as far as
I can tell.
Keep 'em coming.
Cheers

That is caused by my rescaling the image from 1152x864

I was thinking that perhaps granite wasn't the best choice... also I was
planning on scaling the xy much higher than the z. I'm seriously
looking at a density_map. However it takes FOREVER to render, so I
might have to experiment on a small scale....

Looks like a crazed cleaning person with a broom had whisked through there and failed
to
vacuum the air.
