Figure 17-38: Hey! Not bad! Not bad at all! As a
matter of fact, pretty darn passable! But something
I'd like to see is to have the lens flare effect in the
live-action plate carry onto our 'droids just a touch.
Figure 17-36: Hmm … Well, the light is coming
from the correct direction, but the scene is dark.
We could spend a lot of time “hanging” other
lights to mimic the light reflecting off the ground,
pavement, sky, and all that, or we could use our
live-action plate to light our scene!
5. As shown in Figure 17-39,
add a point light, naming it
Flare
. Set its Position to
X=890 mm
,
Y=7.269 m
,
Z=-69 mm
. Set Light
Intensity to
0%
, and activate
Lens Flare
. Set Flare
Intensity to
200%
, deacti-
vate
Fade Off Screen
, set
Flare Dissolve to
69%
, and
set it so that only
Central
Glow
is active. Set Star Fil-
ter to
4 Point
and the star
filter's Rotation Angle to
45º
. (You can do an <
F9
>if
you like; I've already tested it and
know the effect is what I'm looking for,
but it is so
subtle
as to not really merit a
figure of its own.)

What's the big thing that stands out as
being “wrong” when you look at Figure
17-38?
The 'droids aren't casting any shad-
ows
! Compositing shadows onto things
seen in photographic plates is a bit of a
multi-part process with the tools that are a
part of LightWave's basic toolset. (Other
plug-ins exist that streamline shadow
