About Screen Space Lens Flare

Starting with Unity 2023, Screen Space Lens Flare is a built-in post-processing effect in SRP.

I personally like this effect very much, so I decided to port this feature to earlier versions of Unity, so that even Unity 2021/2022 users can use this feature. Screen Space Lens Flare relies on the final RT output of Bloom, so you must turn on Bloom for it to take effect.

Because it is ported backward in a bit of a hacky way, this feature is regard as experimental. At this point, I cannot guarantee that this feature will not have bugs in the editor/buit player of 2021/2022.

<aside> 💡 In some cases, when the streak threshold in the screen space lens flare volume is too low, there may be flickering when moving the mouse in the editor.
