A transparent material and an Ambient Occlusion material are rendered darker when using path tracing in HDRP
How to reproduce:
1. Open the “HDRP Transparent dark bug“ project
2. Open the “OutdoorScene“
3. Enter the Play Mode
4. Observe the Game view
Expected result: The “Sphere“ and the “Cube (6)“ GameObjects are not rendered darker
Actual result: The “Sphere“ and the “Cube (6)“ GameObjects are rendered darker
Reproducible with: 2023.3.0a6, 6000.0.6f1
Not reproducible with: 2021.3.39f1, 2022.3.33f1, 2023.3.0a5
Reproducible on: Windows 10 Pro (22H2)
Not reproducible on: No other environments tested
Could not test on: macOS 14.5 (Intel) (Path tracing not supported)
Notes:
- Also the specular reflection of the light source on the “Sphere“ GameObject with the “Transparent“ material is not visible
- The material “AO OFF“ without Ambient Occlusion is rendered correctly

Resolution Note:
The observed changes in behavior are the result of a deliberate change of how AO is interpreted in the HDRP Path Tracer.
