  1. We are migrating the Unity Forums to Unity Discussions. On July 12, the Unity Forums will become read-only.

    Please, do not make any changes to your username or email addresses at id.unity.com during this transition time.

    It's still possible to reply to existing private message conversations during the migration, but any new replies you post will be missing after the main migration is complete. We'll do our best to migrate these messages in a follow-up step.

    On July 15, Unity Discussions will become read-only until July 18, when the new design and the migrated forum contents will go live.


    Read our full announcement for more information and let us know if you have any questions.

    This is a request for the Unity release team.

    Please add a Warning to the Release Notes when a new Unity version forces full reimport of the project!
    This usually requires careful scheduling to avoid hours of lost productivity.

    Recent versions that forced a full reimport (*):
    2019.3.14f1
    2020.1.0b9
    2020.1.0b10

    * when updating from the previous version of the same release branch

    Big plus one from my side, I am wasting 6+ hours every time this happens. Happened again with 2019.3.15 just today which is super annoying.

    For me since a while every version of the same branch forces full reimport and I don't understand why.
    Probably since 2019.3

    I think I'm partly responsible for this :p. I've been filing quiet a few bug reports related to performance regressions in asset pipeline, and the fixes seem to force reimport the project because of the changes to imported files' cache, especially the hashes. Also, sometimes a new version forces a new version of the scriptable build pipeline which may have something to do with this too.

    But yeah, a warning would be cool, because when you start the reimport you have to go through with it, as it already dirtied the library folder anyway.

    afaik, there's nothing in the unity version that says "reimport the project if it's older". The way it works is that Unity checks if the format of any files have changed, and if so updates (reimports) those files. So this is very project-dependent - Unity can't know if it's a big reimport or not.

    Unless it's one of those instances where the format of every file changes - like a few years back when the .meta file content changed.

    Anyway, Unity could do some metrics where they had a pretty large project or two that they imported from one version to the next, and then they could add a notice if the reimport was longer than normal.
