I talked to Vladimir, this issue seems to be different than [Internal link], so I make this new bug report.
Steps:
- Open attached small repro (20220714_ambient.zip)
- Edit > Preferences > GI Cache > Clean Cache
- Open base scene, hit play
- Click Next on GameView, observe the next scenes do not have ambient lighting
Note: If I open the scenes manually, ambient lighting becomes fine, both SampleScene1 and SampleScene2 has Auto Generate enabled. However our automated tests that runs on Yamato will run the tests without GI cache, so our tests will fail because of no ambient lighting.
Reproducible:
2023.1.0a3.385 (f4fb871d59a7)
2021.3.4f1.243 (cb45f9cae8b7)
