Vignette

In photography, vignetting is the term for the darkening and/or desaturating towards the edges of an image compared to the center. In real life, thick or stacked filters, secondary lenses, and improper lens hoods are usually the cause of this effect. You can use vignetting to draw focus to the center of an image.

Using Vignette

Vignette uses the Volume system, so to enable and modify Vignette properties, you must add a Vignette override to a Volume in your Scene.

To add Vignette to a Volume:

1. In the Scene or Hierarchy view, select a GameObject that contains a Volume component to view it in the Inspector.
2. In the Inspector, navigate to Add Override > Post-processing and click on Vignette. Universal Render Pipeline applies Vignette to any Camera this Volume affects.
