Adaptive Probe Volume baking generates probes only below ground mesh and ignores volume above when baking lighting
Reproduction steps:
1. Open the attached “IN-113477.zip” project
2. Open the “SampleScene”
3. Open the Lighting window (Window > Rendering > Lighting)
4. Click “Generate Lighting”
5. Open the “Rendering Debugger” window (Window > Analysis > Rendering Debugger)
6. Navigate to the “Probe Volumes” tab
7. Enable “Display Probes” under “Probe Visualization”
8. Observe the Probes in the Game view
Expected result: Probes are also generated above the flat mesh, where the Capsule GO is
Actual result: Probes are only generated under the flat ground mesh and downwards
Reproducible with: 2023.2.0b1, 6000.0.59f1, 6000.2.6f1, 6000.3.0b4, 6000.4.0a1
Reproducible on: Windows 11
Not reproducible on: no other environments tested

Resolution Note:
This is by design. The capsule isn't marked as static, so doesn't affect probe placement at all. The guarantee of Adaptive Probe Volumes is that the probes encapsulate/surround the static scene geometry. The static plane is at exactly Y=0, and the probes are also at exactly Y=0. To avoid this issue, move the plane slightly upwards or use the "Fill Empty Spaces" setting in the adaptive probe volumes component.
