Lights

This is the response I got from Jeff Lee who shed some "light" on this. Thanks Jeff!--

Point -> Bulb
Spot -> Klieg
Distant -> Sun
Area -> Bulb or Klieg with increased Width setting

I don't think A:M has an equivalent to "linear"; I tried scaling a
10-meter-wide Klieg's X dimension to 1%, but it still produced the same
light pattern as it did before I scaled it. So it looks like we also only
have a rough equivalent to "Area", since we can't define a rectangular/oval
light source -- just a circular one. Though I suppose you could create a
rectangular "gobo" in front of the light, if you really needed to restrict
it to that particular shape.

It affects how quickly the brightness falls off from the center; linear
scale means that at 80% away from the light center towards the light's
limit of effectiveness, the brightness is down to 20%, whereas with the
inverse-square falloff, there's a more noticeable "curve" to the light's
effect (which gives a more realistic look, IMHO). I don't see a means of
selecting falloff method in A:M, though, so the question is fairly academic
for this list.

Depends on the Radiosity settings in your Choreography.
