+| **Display Probes** | **Probe Shading Mode** | Set what the Rendering Debugger displays. The options are:<ul><li><strong>SH</strong>: Display the [spherical harmonics (SH) lighting data](https://docs.unity3d.com/Manual/LightProbes-TechnicalInformation.html) for the final color calculation. The number of bands depends on the **SH Bands** setting in the active [HDRP Asset](HDRP-Asset.md).</li><li><strong>SHL0</strong>: Display the spherical harmonics (SH) lighting data with only the first band.</li><li><strong>SHL0L1</strong>: Display the spherical Harmonics (SH) lighting data with the first two bands.</li><li><strong>Validity</strong>: Display whether probes are valid, based on the number of backfaces the probe samples. Refer to [Fix issues with Adaptive Probe Volumes](probevolumes-fixissues.md) for more information about probe validity.</li><li><strong>Probe Validity Over Dilation Threshold</strong>: Display red if a probe samples too many backfaces, based on the **Validity Threshold** set in the [Adaptive Probe Volumes panel](probevolumes-lighting-panel-reference.md). This means the probe can't be baked or sampled.</li><li><strong>Invalidated By Adjustment Volumes</strong>: Display probes that a [Probe Adjustment Volume component](probevolumes-adjustment-volume-component-reference.md) has made invalid.</li><li><strong>Size</strong>: Display a different color for each size of [brick](probevolumes-concept.md).</li><li><strong>Sky Occlusion SH</strong>: If you enable [sky occlusion](probevolumes-skyocclusion.md), this setting displays the amount of indirect light the probe receives from the sky that bounced off static GameObjects. The value is a scalar, so it displays as a shade of gray.</li><li><strong>Sky Direction</strong>: Display a green circle that represents the direction from the probe to the sky. This setting displays a red circle if Unity can't calculate the direction, or **Sky Direction** in the [Adaptive Probe Volumes panel](../probevolumes-lighting-panel-reference) is disabled.</li><li>**Probe Occlusion**: Displays whether probes are affected by lights that have their [Light Mode](https://docs.unity3d.com/Manual/LightModes-choose) set to **Mixed**, if you set [Lighting Mode](https://docs.unity3d.com/Manual/lighting-mode) to Shadowmask. Each probe displays up to four overlapping lights.</li></ul>|
