Probe Adjustment Volume component reference

Select a Probe Adjustment Volume Component and open the InspectorA Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. More info
See in Glossary to view its properties.

Refer to the following for more information about using the Probe Adjustment Volume component:

Property	Description
Influence Volume	Sets the shape, size and radius of the Adjustment Volume. The options are: Shape: Set the shape of the Adjustment Volume to either Box or Sphere. Size: Set the size of the Adjustment Volume. This property only appears if you set Shape to Box. Radius: Set the radius of the Adjustment Volume. This property only appears if you set Shape to Sphere.
Mode	Sets how Unity overrides probes inside the Adjustment Volume.

Mode

Value	Description
Invalidate Probes	Mark selected probes as invalid. Refer to How light probe validity works for more information.
Override Validity Threshold	Override the threshold URP uses to determine whether Light ProbesLight probes store information about how light passes through space in your scene. A collection of light probes arranged within a given space can improve lighting on moving objects and static LOD scenery within that space. More info See in Glossary are marked as invalid. Refer to Adjust Dilation for more information.
Apply Virtual Offset	Change the position Light Probes use when sampling the lighting in the sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info See in Glossary during baking. Refer to Adjust Virtual Offset for more information.
Override Virtual Offset Settings	Override the biases URP uses during baking to determine when Light Probes use Virtual Offset, and calculate sampling positions. Refer to Adjust Virtual Offset for more information.
Intensity Scale	Override the intensity of probes to brighten or darken affected areas.
Override Sky Direction	Override the directions Unity uses to sample the ambient probe, if you enable sky occlusion.
Override Sample Count	Override the number of samples Unity uses for Adaptive Probe Volumes.

Mode settings

Property	Description
Dilation Validity Threshold	Override the ratio of backfaces a probe samples before URP considers it invalid. This option only appears if you set Mode to Override Validity Threshold, and you enable Advanced Properties.
Virtual Offset Rotation	Set the rotation angle for the Virtual Offset vector on all probes in the Adjustment Volume. This option only appears if you set Mode to Apply Virtual Offset.
Virtual Offset Distance	Set how far URP pushes probes along the Virtual Offset Rotation vector. This option only appears if you set Mode to Apply Virtual Offset.
Geometry Bias	Sets how far URP pushes a probe’s capture point out of geometry after one of its sampling rays hits geometry. This option only appears if you set Mode to Override Virtual Offset Settings.
Ray Origin Bias	Override the distance between a probe’s center and the point URP uses to determine the origin of that probe’s sampling ray. This can be used to push rays beyond nearby geometry if the geometry causes issues. This option appears only if you set Mode to Override Virtual Offset Settings.
Intensity Scale	Change the brightness of all probes covered by the Probe Volumes Adjustment Volume component. Use this sparingly, because changing the intensity of probe data can lead to inconsistencies in the lighting. This option only appears if you set Mode to Intensity Scale.
Sky Direction	Set the direction Unity uses to sample the ambient probe. This option only appears if you set Mode to Override Sky Direction.

Probes

Property	Description
Direct Sample Count	Set the number of samples Unity uses to calculate the direct light each probe stores. This option only appears if you set Mode to Override Sample Count.
Indirect Sample Count	Set the number of samples Unity uses to calculate the indirect light each probe stores, including environment samples. This option only appears if you set Mode to Override Sample Count.
Sample Count Multiplier	Set the value Unity multiplies Direct Sample Count and Indirect Sample Count by. This option only appears if you set Mode to Override Sample Count.
Max Bounces	Set the number of times Unity bounces light off objects. This option only appears if you set Mode to Override Sample Count.

Sky Occlusion

Property	Description
Sample Count	Set the number of samples Unity uses to calculate the amount of light each probe receives from the sky, if you enable sky occlusion. This option only appears if you set Mode to Override Sample Count.
Max Bounces	Set the number of times Unity bounces light from the sky off objects to calculate the sky occlusion data, if you enable sky occlusion. This option only appears if you set Mode to Override Sample Count.
