There are still one or two issues. The shadow, for example, is not quite
dark enough. There are a number of ways to deal with that. First, if
another artist will be compositing the shot, you will likely render out a
separate shadow pass and the compositor will take care of the shadow
darkness and match it up nicely so the question may be moot. Why
spend time working on a perfect shadow if someone else is going to fid-
dle with it? If you are compositing the shot yourself in LightWave, you
could always use Worley’s Luminous Shadow Darkening tool. This tool
was originally available in Worley’s Gaffer. If you don’t already own Gaf

many more.
Rendering the Element
We have been learning to match lighting by rendering our elements
against the background plate and seeing how well they match up in the
render. Under normal production circumstances, however, after you
match up the lighting, you will almost certainly turn off the background
and render the CG element by itself. This rendered sequence or still
frame will then be handed off to a compositing station where another
artist will import both the background plate and the CG element and
marry them together. The compositing artist (or compositor) who does
