Display Probe Volumes

You can use the Rendering Debugger to check how URP places Light Probes in a Probe Volume, then use Probe Volume settings to configure the layout.

Display Probe Volumes

To display Probe Volumes, open the Rendering Debugger and select the Probe Volume tab.

You can do the following:

• Enable Probe Visualization > Display Probes to display the locations of Light Probes and the lighting they store.
• Enable Subdivision Visualization > Display Bricks to display the outlines of groups of Light Probes ('bricks'). Refer to Understanding probe volumes for more information on bricks.
• Enable Subdivision Visualization > Display Cells to display the outlines of cells, which are groups of bricks used for streaming.
• Enable Subdivision Visualization > Debug Probe Sampling to display how neighboring Light Probes influence a chosen position. Select a surface to display the weights URP uses to sample nearby Light Probes.

If the Rendering Debugger displays invalid probes when you select Display Probes, refer to Fix issues with Probe Volumes.
