Yes just like that. Hot metal typesetting was a mechanical process
requiring a lot of force.

Well to be honest. It was not a standard keyboard. It was a hand built
ruggedised one and the keys were slightly further apart than on a normal
computer keyboard.

Found it.
Parameter (l)user_error was set to "ON". :\
Reading too fast, seeing what I wanted to see, and missing a translate
directive.
(This isn't the first time I've aborted a post because in the middle of trying
to explain what the problem, the error and bleedingly obvious solution jumped
out of the screen and gave my grey matter a good swift kick in the medulla
oblongata...)
Any quick-start tips on dealing with filtered light?
The red I had was WAY too red, maybe the yellow I'm trying now has potential is
I get the filter value right.
I'd like some sort of glow to emanate from the center of the cones without
blasting the rest of the scene with light.
I'm guessing that with radiosity turned on, I need EMISSION in the finish{}
block.

Looks like your shades may not let the light pass through, or maybe the
lights are accidently located inside an opaque part of your fixtures.
You must make sure that the shades have a good bit of transparency. Be
sure that max_trace_level is set high enough. In doubt, increase it by 5.
When using radiosity, backside illumination is also good. Just make sure
that you increase recursion_limit by 1 in that case.

Yes, with radiosity ambient is turned OFF and you need emission to make
something glow.
As for filtered light, trial and error untill you get wat you want...
Also, work with the actual colour of your lights.

Please tell me how to disable that. :-)

Great, is it not?
One of the best methods of fault finding (trouble shooting, for those
west of the Western Isles) is to explain the problem, out loud. It often
becomes clear. :-D

I have the point light sources moved to the proper positions now, what I need to
do is give the impression that there is actually a light THERE - not necessarily
a filament, but that radiating glow that emanates out through the glass.
My knee-jerk reaction is to incorporate media...

Plenty of transparency, and for the moment I'm using that in lieu of filter.
Off to make adjustments and render it out again...

I'm glad you clarified the terminology. "Fault finding" has a pejorative
connotation on this side of the pond. (The trouble with us sharing a universal
language is that it ain't so universal.)

I know, I had that discussion with Darren New, if you remember him, a
few years ago. In Britain "Fault finding" in the technical sense does
not mean apportioning blame. But just finding the fault. In the sense
that you know. We would say "finding fault (with)".
As George Bernard Shaw said. "England and America are two countries
separated by a common language."

And whose fault is that? Huh?

Well, as a geologist I would say, the fault running through the middle
of the Atlantic Ocean ;-)
