Select a Probe Volume and open the Inspector to view its properties.

Property	Description
Mode
	Global	URP sizes this Probe Volume to include all renderers in the scene or Baking Set that have Contribute Global Illumination enabled in their Mesh Renderer component. URP recalculates the volume size every time you save or generate lighting.
	Scene	URP sizes this Probe Volume to include all renderers in the same scene as this Probe Volume. URP recalculates the volume size every time you save or generate lighting.
	Local	Set the size of this Probe Volume manually.
Size		Set the size of this Probe Volume. This setting only appears when you set Mode to Local.
Subdivision Override
	Override Probe Spacing	Override the Probe Spacing set in the Baking Set for this Probe Volume. This cannot exceed the Min Probe Spacing and Max Probe Spacing values in the Probe Volumes panel in the Lighting window.
Geometry Settings
	Override Renderer Filters	Enable filtering by Layer which GameObjects URP considers when it generates probe positions. Use this to exclude certain GameObjects from contributing to Probe Volume lighting.
	Layer Mask	Filter by Layer which GameObjects URP considers when it generates probe positions.
	Min Renderer Size	The smallest Renderer size URP considers when it generates probe positions.
	Fill Empty Spaces	Enable URP filling the empty space between and around Renderers with bricks. Bricks in empty spaces always use the **Max Probe Spacing** value.

Size gizmo

To resize the Probe Volume, use one of the handles of the box gizmo in the Scene view. You can't resize a Probe Volume by changing the Transform component of the GameObject, or using the scale gizmo.

In this screenshot, a red box indicates the box gizmo handles.
