You might be asking why you would darken a scene with a negative
light instead of just turning the lights down. For example, you might have to add a lot of
light to make areas appear properly lit. Depending on the surfaces you??™ve set, the extra
light might make one area look perfect while making other areas too bright. This is where
negative lights come into play. Adding a negative light (any light with a negative light
intensity value) takes away light from a specific area.
Adding Lights
In most cases, you??™re going to use more than one single distant light in your 3D scenes.
This section shows you how to add lights. Follow these simple steps to add lights to
LightWave Layout to get a feel for how they work. And remember, unless you are working
with Auto Key enabled, you??™ll need to create a keyframe to lock your lights into position
after they??™re moved, just like objects.
Exercise 4.1 Adding Lights to Layout
1. Open Layout or select Clear Scene from the File drop-down menu.
This sets Layout to its default of one distant light.
The mini-slider (the left and right arrows) next to the Light Intensity setting in the
Light Properties panel allows you to click and drag values ranging from 0 to 100.
