[MSE] Additively loaded scenes use light probe data from first loaded scene

Progressive Lightmapper


Steps to reproduce:

1. Open attached project ""
2. Inspect all of the scenes, notice that each has lightprobes baked individually
3. Open scene "Scene_A" and drop "Scene_B" to hierarchy to enable MSE
4. Move green light of scene "Scene_A" and notice that light probes of "Scene_B" uses light of "Scene_A" but whole group of scenes use probe position of "Scene_B"

Reproduced with: 5.3.6p2, 5.4.0p4, 5.5.0b1

  1. Resolution Note (fix version 2019.3):

    This issue has been fixed with introducing the light probe merging feature for additively loaded scenes: If you still can reproduce it after applying this feature, feel free to reopen the case.

    This for instance does not work:
    SceneManager.LoadSceneAsync("level2", LoadSceneMode.Additive);

    How is LightProbes.Tetrahedralize supposed to work? I load a scene additively with 2019.3.1f1 and 2020.1.0a23 and it still doesn't do what it is supposed to.

    Is there a chance to get a fix for 2018.3.6 + or has someone found a workaround.

    Is there a possible fix for this yet? Finding it extremely difficult to work with multiple scenes and combining light probe groups.

    Very disappointed to see that the only progess made on this if you can call it that, up to 2018.2 is to include a warning message telling people this aint going to work!
    As there is now no option to vote on this due to it being "Postponed" I'm afraid I will have to vote with my wallet and cancel my subscription to Unity Plus.

    Still happening in 2017.3.1f1, hope it gets fixed soon or I will have to change my scenes from additive to single mode...
