Regression
Yes
Adaptive Probe Volumes are not applied to URP Simple Lit or Lit Shaders when using "Mixed" Light Mode
Reproduction steps:
1. Open the attached “IN-94576.zip” project
2. Open the “SampleScene”
3. From the Hierarchy, select the “Directional Light” GameObject
4. In the Inspector, make sure the Light “Mode” is set to “Mixed”
5. Open the “Lighting” Window (Window > Rendering > Lighting)
6. Click “Generate Lighting”
7. Observe the “model_Props_Barrel__Occluded_A” and “model_Props_Barrel__Occluded_B” GameObjects
Expected result: The GameObjects are occluded and not lit
Actual result: The GameObjects are lit
Reproducible with: 6000.0.35f1, 6000.0.40f1, 6000.1.0b8, 6000.2.0a5
Not reproducible with: 6000.0.34f1
Couldn’t test with: 2022.3.59f1 (APV not available)
Reproducible on: Windows 11
Not reproducible on: no other environment tested
Note:
- Setting the Light “Mode” to “Baked” and then Generating Lighting, shows the expected result

Can confirm the issue is also present in the latest 6000.0.41 LTS version.

But this behavior has always worked ok. Subtractive lightmaps with directional mixed lighting light and APVs have always worked ok on Unity 6 until after Unity 6000.0.32 LTS version. 😢

- Debug Console does not reappear when disabling and re-enabling Debug.developerConsoleEnabled
Resolution Note:
This is expected since the project is using Subtractive Mixed Lighting Mode with shadow casting turned of for main light in the active URP Asset.
To get the desired result set the Lighting Mode under Mixed Lighting in the Lighting window to Shadowmask. And turn on the main light shadow casting in the active URP Asset.
