Since I didn't come near finishing this for the latest round, I thought I
would post it here anyway. Far from finished, I only had a few uninterrupted
hours to work on it and spent most of that getting the nearly invisible
tendrils that creep out from the door jam.

The red lights end abruptly, and it really needs for the green tendril glow
to light up the corridor...radiosity? This has definite potential.

    That's next, but it think I will use lights.

    Plus I need a thousand details. Like the rest of the door and the Brick
Wall macro... This is what may never get done, I can't seem to do that kind
of work unless I have hours at a stretch. Usually I have only a few minutes
at a time. I have that often during the day, but rarely a whole hour at
once.

I agree with Andy though, even if it is a shadow it doesn't help the realism
any. I think it would be better if you had the lights fade out instead of end
in a shard circle. Perhaps increase the falloff rate, or make them into area
lights.

    Well I agree too. Maybe it will be as simple as moving the ring up a
small amount.

The problem may also be that the lights here are pointlights.

Imaginative... Kind of a Outer Limits type thing I thought.
No one mentioned the fluorescent light sharp shadows.  Area lights all around would be
the answer I'd think.

    I tried that. Maybe there is a way to get area lights to light up a
bigger area? It made the FL. fixture cast light only on one point of the
ceiling and walls. I ended up with a line of lights all the way down the
fluorescent tubes. I tried giving them a little random xy movement but that
just made banding. Maybe I should try both point lights and area lights, but
that still might make a very bright point in the center of the fixture.

    I also tried area lights in the emergency lights. Until I got very small
ones I couldn't get the grain out of the shadows. Then the line came back.
Maybe the cage should be shadowless?

    I did try radiosity. I would have to start over and I don't think glows
work very well, or at least how I expect them to work, with radiosity. Maybe
I will try again.

Or maybe wait until there are true "area" area lights?  Long wished for, never has
happened yet... that I know
of.
Know what you mean by radiosity and glows.  Take a look at this ugly beauty I attached
here.  It ain't workin'!
Note I labeled it "betterrad", well you ought to have seen the worse one.

Depends on what you mean...you can use an object with a high ambient 
texture to do it, or you can use a grid of light_sources. If you mean 
having area lights be calculated for all illumination instead of just 
shadows, that would probably be nearly as slow as using a grid of many 
individual lights, though a bit easier on the memory. It isn't a bad 
idea, just hasn't ever really been needed...

"Ugly beauty"...
Well, this is probably happening because glows can get extremely bright 
toward the center...sometimes radiosity will send out a sample that 
happens to make a near miss, and the extreme brightness throws off the 
radiosity calculation, making a "splotch". I have been thinking of a 
"max_brightness" keyword to fix this...
