Ray Tracing Settings
In the High Definition Render Pipeline (HDRP), various ray-traced effects share common properties. Most of them are constants, but you may find it useful to control some of them. Use this Volume Override to change these values.
Setting the ray-tracing global parameters
- In the Scene or Hierarchy view, select a GameObject that contains a Volume component to view it in the Inspector.
- In the Inspector, navigate to Add Override > Ray Tracing and click on Ray Tracing Settings.
Properties
| Property | Description |
|---|---|
| Ray Bias | Specifies the bias value HDRP applies when casting rays for all effects. This value should remain unchained unless your scene scale is significantly smaller or larger than average. |
| Extend Shadow Culling | Extends the sets of GameObjects that HDRP includes in shadow maps for more accurate shadows in ray traced effects. |
| Extend Camera Culling | Extends the sets of GameObjects that HDRP includes in the rendering. This is a way to force skinned mesh animations for GameObjects that are not in the frustum. |
| Directional Shadow Ray Length | Controls the maximal ray length for ray traced directional shadows. |
| Directional Shadow Fallback Intensity | The shadow intensity value HDRP applies to a point when there is a Directional Light in the Scene and the point is outside the Light's shadow cascade coverage. This property helps to remove light leaking in certain environments, such as an interior room with a Directional Light outside. |
