    Hello ! :)

    While profiling my prototype on Timeline, I noticed that PlayableDirector.get_duration() is allocating memory. Deep profiling shows that the allocation is caused by PlayableAsset.Internal_GetPlayableAssetDuration().

    Is there a reason why or should it be considered a bug ?


    (I'm trying to squeeze the performance out of Timeline so I might come back with other notes like this :p)

    Hello Midiphony-panda,

    We had an internal report of this earlier this year. There is a fix for this in Timeline 1.6.2, which you should be able to get in the package manager with Unity 2020.3.

    I will back-port the fix to Timeline 1.4 and 1.5, but can't give a date for when they will be released.
