Plugin Node Inputs

The Flares OFX plugin exposes multiple input connections that define how lens flares are generated and driven. Each input serves a specific role in controlling resolution, light placement, and visual detail.

Format

The Format input defines the resolution at which the plugin generates flares.

The flare output resolution matches the resolution of this input
For example, a 1920×1080 format input results in flares rendered at 1920×1080
This ensures consistent scaling and alignment with the target image

Drive

The Drive input is used for pixel-driven flares.

An image is analyzed to detect bright areas
These areas define the position and intensity of flare lights
The input can be any resolution
It is automatically scaled to match the plugin’s working resolution

This input is optional and only required when using pixel-driven workflows.

Iris Texture

The Iris Texture input provides a custom texture for the aperture shape.

Used when custom aperture or custom starburst shapes are enabled
Allows full artistic control over aperture
Typically a grayscale texture

Dirt Texture

The Dirt Texture input supplies a dirt or smudge map applied to the front lens.

Used to simulate dust, fingerprints, or grime
Most visible in bright flare regions
Helps add realism and photographic imperfection

Occlusion

The Occlusion input is used in position-driven or light-driven flare modes.

The plugin reads this texture to determine which parts of the light are blocked
Allows flares to be partially or fully occluded by scene elements
Useful for integrating flares into complex composites

Summary

Format defines flare render resolution
Drive controls pixel-driven light placement
Iris Texture customizes aperture shape
Dirt Texture adds front-lens imperfections
Occlusion enables realistic light blocking

These inputs make the OpenFX node flexible and adaptable to a wide range of compositing workflows.
