LightRays

Output View / Source Regions, Rays Alone, Final Result

Chooses whether the Viewer shows detected source regions, the rays by themselves, or the composite result.

Input Alpha / Masks The Source Regions, Is Used For Compositing, Is The Source Of The Glow

Chooses whether input alpha masks source detection, participates in compositing, or drives the glow source.

Source Of Rays / Bright Regions, Edges

Controls how the operation treats image or region edges.

Ray Directions / At An Angle, From A Location

Selects the light-ray direction mode.

Chooses how the light-ray direction is determined.

Ray Dropoff / Default, soft; Keep Shape Of Source; CCD Bloom Harsh; CCD Bloom Soft

Chooses the radial falloff profile used to shape the generated rays.

Relative Length Red

Scales ray length for the red channel.

Relative Length Green

Scales ray length for the green channel.

Relative Length Blue

Scales ray length for the blue channel.

Soften

Softens the transition at the edge of the mask, matte or effect.

Composite Type

Selects the Composite Type.

Chooses the mathematical or operational mode used for this part of the node. Available choices include Normal, Add, Subtract, Difference, Multiply, Overlay, and Hard Light.

Source Regions / Rays Alone / Final Result

Chooses whether the output displays source regions, the rays alone, or the final composite.

Input Alpha

Chooses how the source alpha participates in ray generation and final compositing.

Source Of Rays

Chooses bright regions or edges as the ray source.

Source Threshold

Controls which areas are bright enough to emit rays.

Ray Directions

Chooses an angle-based or point-origin ray model.

Position X / Y

Sets the origin when rays come from a location.

Shimmer

Opens the controls that add animated variation and shimmer to the rays.

Ray Dropoff

Defines how energy fades along the rays.

Length

Controls ray extent.

Relative Length Red / Green / Blue

Sets ray length independently for the red, green and blue channels.

Use channel-specific controls when the operation should not affect all components equally.

Softness

Blurs and integrates the ray structure.

Brightness

Sets the brightness of the effect.

Gamma

Adjusts the midtone response without moving the black and white points equally.

Saturation

Adjusts color saturation.

Colorize / Colorize Color / Red / Green / Blue

Sets the RGB tint applied when LightRays colorization is enabled.

Use channel-specific controls when the operation should not affect all components equally.

Add Atmosphere

Adds noisy atmospheric variation to the rays.

Atmosphere Strength

Adjusts the amount of atmospheric texture mixed into the rays.

Atmosphere Detail

Sets the amount of fine structure in the atmospheric ray texture.

Atmosphere Scale

Sets the spatial scale of the atmospheric texture modulating the light rays.

H vs V Ratio

Stretches the atmospheric texture horizontally or vertically relative to its base scale.

Evolution

Moves the atmospheric texture through its procedural evolution over time.

Seethe

Sets how strongly the atmospheric pattern evolves internally over time.

Composite Type

Selects the Composite Type.

Chooses the mathematical or operational mode used for this part of the node.

Source Recovery

Restores some of the original source into the processed result.

Useful when a glow, ray or similar effect has obscured the bright source that generated it.
