The Film Grain effect simulates the random optical texture of photographic film, usually caused by small particles being present on the physical film.
|
|
|
|
## Using Film Grain
|
|
|
|
**Film Grain** uses the [Volume](Volumes.md) framework, so to enable and modify **Film Grain** properties, you must add a **Film Grain** override to a [Volume](Volumes.md) in your scene. To add **Film Grain** 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 **Film Grain**. URP now applies **Film Grain** to any Camera this Volume affects.
