Dynamic Ray

The DynamicRayLayer creates animated, stylized light rays that respond to sun direction and camera angle. This layer is ideal for simulating sunbeams, magical energy rays, or sci-fi scanning effects. It inherits all fading and variation options from StaticRayLayer.

Common Uses:

• Sun shafts breaking through clouds or windows

• Magical spell beams or energy rays

• Stylized sci-fi scanning or spotlight effects

Variables

Name	Type	Description
rayLength	float	Maximum distance each ray will travel.
bidirectional	bool	If true, rays are cast both forward and backward from the mesh surface.
angleOpacityEffect	float	How much the angle between the sun direction and the ray’s forward vector affects opacity (0–1).
angleRaylengthEffect	float	How much the angle between the sun direction and the ray’s forward vector affects ray length (0–1).
autoAssignSun	bool	Automatically assign the primary directional light as the sun.
useLumenSunScript	bool	Use a custom script to control the Lumen sun behavior.
sunDirection	Vector3	World-space direction of the simulated sun.

Inherits all fading and variation options from StaticRayLayer.

Example:

• Use DynamicRayLayer for a magical portal that emits swirling, animated rays.

• Add to a window to create animated god rays that move as the sun moves.
