Reproduction steps:
1. Open the attached “IN-93909.zip“ project
2. Open the “Scene” Scene
3. Double click on the “Observe” GameObject from the Hierarchy to move the Scene view to Probes
4. In the Lighting Window, click Generate Lighting
5. Observe the Light Probes
Expected result: All Probes are lit the same
Actual result: Some of the Probes are black in very lit areas
Reproducible with: 2023.1.0a22, 2022.3.57f1
Not reproducible with: 6000.0.35f1, 6000.1.0b5, 6000.2.0b2
Fixed in: 2023.1.0a23
Reproducible on: Windows 10 (User reported), Windows 11
Not reproducible on: No other environment tested
Notes:
- Generating Lighting after unchecking "Baked Global Illumination" in the "Mixed Lighting" section of the "Lighting" Window, makes the issue not reproduce
- Disabling the "Light Probe Group Channel Entry Out" GameObject in the Hierarchy and then Generating Lighting, makes different Probes than before render incorrectly
- Merging all Light Probes by clicking on the “Light Probe Groups" GameObject in the Hierarchy and click on button "Merge 7 LightProbeGroup components into a new one attached to this object" also makes the issue not reproduce and correctly lits the Probes
