Using Source Lights
Source light is the light that comes from a controlled light source. You can add an unlimited number of source lights to a 3D composite, as well as change their position and control their characteristics. All of the light properties are keyframeable.
Note: You animate lights in the same way as any other object in combustion. For information, see Keyframing.
To view the effect of lighting in the composite, the Render Effects options must be enabled in the Settings controls. For more information, see Displaying Light in a Composite.
