Global Illumination


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"

    I confirm that it's not fixed in 2017.2. I implemented a temporary solution, detailed in this topic :

    Hope it will help.

    If this is not fixed, then why is it marked as fixed?

    Lighting team at Unity is well aware about this bug and currently, it is on team's roadmap, it is planned to be addressed during the first quarter of 2018.
    Sorry for the inconvenience that this issue causes for you.

    Here is another closely related (the same?) issue that was reported to be fixed in 2017.3, but could still be reproduced in the latest beta. I contacted the Unity support and they've acknowledged and reopened it.

    I observed this issue on 5.6.2f1. The light probe data used is from the last scene loaded.

    I have this in 2017.2 as well. It's basically rendered a whole week of work creating a multi-scene loading engine for smooth loading in VR 100% useless.

    Not happy that I'm paying pro for this not to be fixed in a whole year..

    Yup I'm definitely hitting this issue in 2017.1. Planning to try rearchitecting my scenes or something from this thread:
