Probe Volumes Options Override reference
To add a Probe Volumes Options Override, do the following:
- Add a Volume to your Scene and make sure its area overlaps the position of the camera.
- Select Add Override, then select Lighting > Probe Volumes Options.
Refer to Fix issues with Probe Volumes for more information about using the Probe Volumes Options Override.
| Property | Description |
|---|---|
| Normal Bias | Enable to move the position used by shaded pixels when sampling Light Probes. The value is in meters. This affects how sampling is moved along the pixel's surface normal. |
| View Bias | Enable to move the sampling position towards the camera when sampling Light Probes. The results of View Bias vary depending on the camera position. The value is in meters. |
| Scale Bias with Min Probe Distance | Scale the Normal Bias or View Bias so it's proportional to the spacing between Light Probes in a brick. |
| Sampling Noise | Enable to increase or decrease the amount of noise HDRP adds to the position used by shaded pixels when sampling Light Probes. This can help fix seams between bricks. |
| Animate Sampling Noise | Enable to animate sampling noise when Temporal Anti-Aliasing (TAA) is enabled. This can make noise patterns less visible. |
| Leak Reduction Mode | Enable to choose the method Unity uses to reduce leaks. Refer to Fix light leaks. Options: • Validity and Normal Based: Enable to make HDRP prevent invalid Light Probes contributing to the lighting result, and give Light Probes more weight than others based on the GameObject pixel's sampling position. • None: No leak reduction. |
| Min Valid Dot Product Value | Enable to make HDRP reduce a Light Probe's influence on a GameObject if the direction towards the Light Probe is too different to the GameObject's surface normal direction. The value is the minimum dot product between the two directions where HDRP will reduce the Light Probe's influence. |
| Occlusion Only Reflection Normalization | Enable to limit Reflection Probe Normalization so it only decreases the intensity of reflections. Keep this enabled to reduce light leaks. Refer to Frame Settings. |
