    Hi all

    I want to hear your opinion about GI cache and sharing it with SVN or other SVN like system.
    Because computing GI every time when is some change in level is little bit time consuming, also when every single member of team must to do it.
    Some ideas or experience with sharing GI cache?

    Thanks for answers and ideas.

    In theory, once you complete a manual pre-comp GI bake, the LightingData.asset that is written to a subfolder of the scene file should contain all the necessary lighting data (editor only). However in practice, we've had inconsistent or just wrong results when checking that file into the depot, getting it on a different system, then loading the scene. I've not yet figured out exactly why this is.

    Hi! As mentioned it should be sufficient to version the Lighting Data Asset. Did anyone of you file a bug report on inconsistent behavior?
    I wouldn't recommend versioning the GI Cache but you should be able to prime the cache of one machine with cache files from another one. For our LAN distributed build prototype we shared the GI Cache files over the network.

    My team meet the same problem. We worked on Unity5.4.2f2 and the GI looks different. I tried to copy the scene file, the lighting data files and gi cache files to another folder and copy them back one by one. But I can't get the same GI result.

    Any thoughts for it will be helpful.
