Remarks

AmbientLight is one of the four light types derived from CompositionLight.

Light Description
AmbientLight A light source that emits non directional light that appears to have been reflected by everything in the scene.
DistantLight An infinitely large distant light source that emits light in a single direction.
PointLight A point source of light that emits light in all directions.
SpotLight A light source that emits inner and outer cones of light.

Note

A Visual cannot be targeted by more than two non-ambient lights (PointLight, SpotLight or DistantLight).
