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 objects proximity to the light. This is Motion’s
default light, and it produces results similar to that of an incandescent light bulb.
