# Volume Overrides

__Volume Overrides__ let you change or extend the default properties in a [Volume Profile](VolumeProfile.md).

URP implements post-processing effects as Volume Overrides. For example, the following image shows the Vignette post-processing effect in the URP Template SampleScene.

In a the Volume Override, checkboxes to the left of each property let you enable or disable specific properties. If you disable a property, URP uses the Volume’s default value for that property instead. To turn all properties on or off, use the __All__ or __None__ shortcuts above the property list.
