Light rays
Stretches the layer's highlights away from a center point and composites them over the original image. The rays can extend past the layer's edges. This effect requires GPU textures and GLSL execution.

Properties
Center
Center of the rays, relative to the complete input image. It can also be placed outside the image.
- Type:
RelativePoint - Default:
(50%, 50%) - Animatable: Yes
Length (%) (Length)
Outward extension relative to the distance from the center. 100 doubles that distance; 0 disables the rays.
- Type:
float - Default:
50 - Animatable: Yes
- Range:
[0, ∞)
Decay (%) (Decay)
Fades the light along each ray. 0 keeps an even strength; higher values fade more quickly.
- Type:
float - Default:
50 - Animatable: Yes
- Range:
[0, 100]
Intensity
Light strength multiplier. 0 disables the rays; 1 is normal strength.
- Type:
float - Default:
1 - Animatable: Yes
- Range:
[0, ∞)
Threshold
Brightness used to select highlights in linear light. 1 is reference white.
- Type:
float - Default:
0.5 - Animatable: Yes
- Range:
[0, ∞)
Softness (%) (SoftKnee)
Smooths the brightness threshold. 0 keeps a hard cutoff; 100 spreads the transition from zero to twice the threshold.
- Type:
float - Default:
50 - Animatable: Yes
- Range:
[0, 100]
Usage
Put Center on or behind the light source, then adjust Length and Decay for how far the rays reach. Animate Center to follow a moving light.
