Lighting Debug Panel

The Lighting Debug Panel contains many tools for visualization various component of the lighting in the scene, shadows, direct and indirect lighting, etc.

Debug Item	Description
Enable Light By Type	Allows the user to enable or disable lights in the scene based on their type.
Shadow Debug Mode	Various overlays showing shadows.
- Visualize Punctual Light Atlas	Shows an overlay of the whole punctual lights shadow atlas.
- Visualize Directional Light Atlas	Shows an overlay of the whole directional lights shadow atlas.
- Visualize AreaLight Atlas	Shows an overlay of the whole area lights shadow atlas.
- Visualize Shadow Map	Shows an overlay of a single shadow map.
- - Use Selection	Shows the shadow map of the selected light in the editor.
- - Shadow Map Index	Shows the shadow map of the visible shadow casting light at the given index.
- Single Shadow	Replace lighting in the scene with only the selected light rendered as black and white.
- - Use Selection	Shows the shadow map of the selected light in the editor.
- - Shadow Map Index	Shows the shadow map of the visible shadow casting light at the given index.
Global Shadow Scale Factor	Change the global scale applied to shadow rendering resolution.
Clear Shadow Atlas	Allows user to force a full clear of the shadow atlases each frame.
Shadow Range Min/Max Values	Allows users to rescale the range of value displayed in the various shadow map debug overlays.
Lighting/Fullscreen Debug Mode	Shows various components of the lighting in the scene (Diffuse, Specular, Cascades, Luminance, ...)
Override Smoothness	When using any of the previous lighting debug modes, allows user to override smoothness for the whole scene.
Override Albedo	When using any of the previous lighting debug modes, allows user to override albedo for the whole scene.
Override Normal	When using any of the previous lighting debug modes, allows user to override normals for the whole scene.
Override Specular Color	When using any of the previous lighting debug modes, allows user to override specular color for the whole scene.

Tile/Cluster Debug	Visualization modes for HDRP internal lighting structures
- Tile	Shows an overlay of each lighting tiles and the number of light in them.
- Cluster	Shows an overlay of each lighting cluster intersecting opaque geometry and the number of light in them.
- Material Feature Variants	Shows the index of the lighting shader variant used for this tile. Variants descriptions can be found in the lit.hlsl file.
Display Sky Reflection	Display an overlay of the cube map used generated by the current sky and used for lighting.
