Screen space lens flare reference

[!include]

Property	Description
Intensity	Set the strength of all the types of lens flares. If the value is 0, HDRP doesn't calculate or render any lens flares. The default is 0.
Tint Color	Set the color HDRP uses to tint all the types of lens flares. The default is white.
Bloom Mip Bias	Set the mipmap level HDRP uses to sample the Bloom pyramid and create the lens flares. The higher the mipmap level, the smaller and more pixelated the sample source, and the blurrier the result. The range is 0 through 5. 0 is the full-resolution mipmap level. The default is 1. Refer to Mipmaps introduction for more information. This property only appears if you open the More (⋮) menu and select Show Additional Properties.

Flares

Use the Flares settings to control regular flares, reversed flares and warped flares.

Property		Description
Regular Multiplier		Set the strength of regular flares. If the value is 0, HDRP doesn't calculate or render regular flares. The default is 1.
Reversed Multiplier		Set the strength of reversed flares. If the value is 0, HDRP doesn't calculate or render reversed flares. The default is 1.
Warped Multipler		Set the strength of warped flares. If the value is 0, HDRP doesn't calculate or render warped flares. The default is 1.
	Scale	Scale the width (x) and height (y) of warped flares. The defaults are 1. This property only appears if you open the More (⋮) menu and select Show Additional Properties.
Samples		Set the number of times HDRP repeats the regular, reversed and warped flares. The range is 1 through 3. The default is 1. Increasing Samples has a big impact on performance.
	Sample Dimmer	Set the strength of the lens flares HDRP adds if you set Samples to 2 or 3. The higher the value, the less intense the flares. This property only appears if you open the More (⋮) menu and select Show Additional Properties.
Vignette Effect		Set the strength of the regular, reversed and warped flares in a circular area in the center of the screen. Use Vignette Effect to avoid lens flare obscuring the scene too much. The default value is 1, which means HDRP doesn't render flares at the center of the screen.
Starting Position		Control how far the position of the regular, reversed and warped flares differ from the bright area they're sampled from, in metres. If the value is 0, HDRP places the lens flares at the same position as the bright areas they're sampled from. The range is 1 through 3. The default is 1.25.
Scale		Set the size of regular, reversed and warped lens flares. The range is 1 through 4. The default is 1.5.

Streaks

Use the Streaks settings to control flares stretched in one direction.

Property		Description
Multiplier		Set the strength of streaks. If the value is 0, HDRP doesn't calculate or render streaks. The default is 1.
	Length	Set the length of streaks. The range is 0 through 1. 1 is the approximate width of the screen. The default value is 0.5.
	Orientation	Set the angle of streaks, in degrees. The default value is 0, which creates horizontal streaks.
	Threshold	Control how localized the streak effect is. The higher the Threshold, the more localized the effect. The range is 0 through 1. The default value is 0.25.
	Resolution	Control the resolution detail of streaks. HDRP renders lower-resolution streaks faster. The options are Half, Quarter and Eighth full resolution. This property only appears if you open the More (⋮) menu and select Show Additional Properties.

The effect of changing Threshold from 0 (a larger flare effect) to 1 (a smaller flare effect).

Chromatic Aberration

Use the Chromatic Aberration settings to control chromatic aberration on all the lens flare types. Chromatic aberration splits light into its color components, which mimics the effect that a real-world camera produces when its lens fails to join all colors to the same point.

The chromatic aberration effect is strongest at the edges of the screen, and decreases in strength towards the center of the screen.

Property	Description
Spectral Lut	Assign a spectral lookup table texture that specifies how HDRP splits the light into color components, for example green and purple. You can create a custom spectral lookup table texture in any image editing software, or use a spectral lookup table texture from the Additional Post-Processing Data sample package. Leave this field empty to use a default texture that splits the light into red, green, and blue.
Intensity	Set the strength of the chromatic aberration effect. If the value is 0, HDRP doesn't split the colors.
Samples	Set the number of samples HDRP uses for the effect. The higher the number of samples, the smoother the gradient between the split color components, but the higher the impact on performance. The range is 3 through 8. The default is 3.
