# Debugging ray-traced effects
|
|
|
|
The High Definition Render Pipeline (HDRP) includes the [Render Pipeline Debug window](Render-Pipeline-Debug-Window.md), which you can use to debug and understand ray-traced effect in HDRP. To debug raytraced effects:
|
|
|
|
1. Open the debug menu, select **Window > Render Pipeline > Render Pipeline Debug**.
|
|
2. Select the **Lighting** panel.
|
|
3. Use the **Fullscreen Debug Mode** drop-down menu to select which ray tracing effect to debug.
|
|
|
|
|
|
|
|
**Light Cluster [Debug Mode](Ray-Tracing-Debug.md)**: The red regions show where the number of lights per cell is equal to the maximum number of lights per cell.
|
|
## Debug modes
|
|
|
|
| **Fullscreen Debug Mode** | **Description** |
|
|
| --------------------------- | ------------------------------------------------------------ |
|
|
| **Screen Space Ambient Occlusion** | When [Ray-Traced Ambient Occlusion](Ray-Traced-Ambient-Occlusion.md) is active, this displays the screen space buffer that holds the ambient occlusion. |
|
|
| **Screen Space Reflection** | When [Ray-Traced Reflections](Ray-Traced-Reflections.md) are active, this displays the ray-traced reflections. |
|
|
| **Transparent Screen Space Reflection** | When [Ray-Traced Reflections](Ray-Traced-Reflections.md) are active, this displays the ray-traced reflections on transparent objects. |
|
|
| **Contact Shadows** | When [Ray-Traced Contact Shadows](Ray-Traced-Contact-Shadows.md) are active, this displays the ray-traced contact shadows. |
|
|
| **Screen Space Shadows** | When screen space shadows are active, this displays the set of screen space shadows. If you select this option, Unity exposes the **Screen Space Shadow Index** slider that allows you to change the currently active shadows. Area lights shadows take two channels. |
|
|
| **Screen Space Global Illumination** | When [Ray-Traced Global Illumination](Ray-Traced-Global-Illumination.md) is active, this displays a screen space buffer that holds the indirect diffuse lighting. |
|
|
| **Recursive Ray-Tracing** | When [Recursive Ray Tracing](Ray-Tracing-Recursive-Rendering.md) is active, this displays the pixels that have been evaluated using the effect. |
|
|
| **Ray-Traced Subsurface Scattering** | When [Ray-Traced Subsurface Scattering](Ray-Traced-Subsurface-Scattering.md) is active, this displays the subsurface lighting value for the pixels that have been evaluated using the technique. |
|
|
| **Light Cluster** | This displays the cluster using a debug view that allows you to see the regions of the Scene where light density is higher, and potentially more resource-intensive to evaluate. |
