Light3D

Inherits: VisualInstance3D < Node3D < Node < Object

Inherited By: DirectionalLight3D, OmniLight3D, SpotLight3D

Provides a base class for different kinds of light nodes.

Description

Light3D is the abstract base class for light nodes. As it can't be instantiated, it shouldn't be used directly. Other types of light nodes inherit from it. Light3D contains the common variables and parameters used for lighting.
