UE4 Lens Flare

Unreal Engine 4.9

Post Process Effects

The Lens Flare effect is an image-based technique that simulates the scattering of light when viewing bright objects due to imperfections in camera lenses.

PropertyDescriptionTintTints the color of the entire lens flare effect.

Lens Flare Tint (1.0, 1.0, 1.0)

Lens Flare Tint (0.25, 1.0, 1.0)

ThresholdDefines the minimum brightness of pixels that contribute to the lens flare. Higher thresholds keep content that is too dark too see from being blurred, improving performance as the fill rate cost increases linearly with the amount of pixels passing the threshold.

Lens Flare Threshold - 0.1

Lens Flare Threshold - 8

Bokeh SizeScales the radius of the Bokeh shape. Possible uses: tweak image based lens flare look and performance (2x radius -> 4x more fill rate).

Lens Flare Size - 1

Lens Flare Size - 8

Bokeh ShapeThe texture to use to define the shape of the lens flares.

Lens Flare Shape - Default

Lens Flare Shape - Square

Lens Flare Tints 1/2/3/4/5/6/7/8Tints the color of each individual lens flare.IntensityBrightness scale of the image cased lens flares (linear).
