It did! Thanks for adding another piece to this puzzle.
The .8 rgb values weren't quite high enough, but I'm rerendering it now with the
values a bit higher. I'll post the results tonight.

So, just out of curiousity... where in my picture, or rather what spot on the
truck or background is <0, 0 ,0>? From what I've previously understood about
the directions I would have guessed that value is out of the frame. Or is that
the whole point? Is it, in fact, pointing to somewhere far off to the right?
Because it seems as though the light is coming from center left (left of the
cab) and pointing almost right at it, without further illuminating the ladder
above.

Yes. :)
I think someone else mentioned that the combined total of your lights shouldn't
be more than about 2 or 3?

I'm curious to see what effect this will have. I will try it tonight. I assume
it's just a troubleshooting technique? To help you better place/aim your
lights? If so, it's exactly what I was looking for.
Thanks again!

| (...) Unless L3P shifts everything (which I doubt), pov <0,0,0> is at the same place as LDRAW <0, 0, 0> - probably close to the first brick you added to the model :-) I don't know what LPub does. -- Anders Isaksson, Sweden BlockCAD: (2 URLs) (21 years ago, 17-Jul-03, to lugnet.cad.ray)
