Directional: A directional light emits parallel rays of light in a specied direction from a
source located at an innite distance. Only the rotation of this light has bearing on its eect.
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 fallo 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 aected by the light.
