Light Rays
A “rays of light” effect that simulates volumetric lighting emerging from light sources defined by
a threshold you define. The effect mimics what are sometimes called “god rays” in the sky, or
other highly directional glow effects.
Main Controls
The Main controls include:
 Select Output: Lets you preview the image with different stages of the Lightray effect
applied, viewing the Final Image, Lightrays Alone, and Source Regions.
 Source of Rays: Lets you choose the emitter of the rays, using Bright Regions or Edges.
 Source Threshold: A slider that lets you choose the limit at which light areas of the
image emit rays.
Position
Position parameters let you define the direction rays take.
 Ray Directions: A pop-up menu that lets you choose either “From A Location,” which
exposes controls to let you choose an X or Y position to define a point of origin that
defines the angle of the light beams, or “At an Angle,” which exposes controls to let you
choose an overall orientation for the rays.
Appearance
Appearance parameters let you customize the ray effect.
 Ray Dropoff: A pop-up with four options.
–
Default (soft): Produces soft, indistinct rays of light that appear to fade away as they
stream out.
–
Keep Shape of Source: The edge of the light rays are defined by the shape that
emitted them.
–
CCD Bloom Harsh: Severely raises the brightness of the part of the image that’s
emitting rays as Length is raised, resulting in harsh glow or bloom in the image.
–
CCD Bloom Soft: Gently raises the brightness of the part of the image that’s emitting
rays as Length is raised, resulting in a very gentle lightning of the image.
 Length: Lets you make the rays longer or shorter.
 Soften: Lets you blur the rays being emitted.
 Brightness: Lets you adjust how bright the rays are.
 Color: A color picker and eyedropper let you define a color with which to tint the rays.
