Directional: A directional light emits parallel rays of light in a specified direction from a
source located at an infinite distance. Only the rotation of this light has bearing on its effect.
A directional light icon, in conjunction with the transform controls, can be used to assist in
visualizing the direction the light is traveling in a scene. The directional light icon appears as
a cylinder with one end removed. The circle represents the back of the light, and the lines
indicate the direction in which the light is traveling.

Point: A point light emits light outward from a single point in 3D space in all directions.
Optionally, you can add falloff based on an object’s proximity to the light. This is Motion’s
default light, and it produces results similar to that of an incandescent light bulb.

Spot: A spot light emits light from a conical light source and casts an elliptical pattern on
objects hit by the light. Using a spot light allows for a high degree of accuracy when you
need to limit the area affected by the light.

Color: A standard set of controls that enable you to select the color of the light.
