    Summary

    Player missed references to
    Playable Asset
    that included in Streamed AssetBundle built before Unity 2018.4.

    Detail

    I'm upgrading my project to Unity 2019.1.3f1.

    I added asmdef reference to
    Unity.Timeline
    into my asmdef that uses some classes under
    UnityEngine.Playables
    namespace.
    And I removed all compile error in Editor.

    Then, when I play the Editor and load some Streamed AssetBundles built for Standalone, the Timeline that is supposed to be played does not play.

    And warning messages displays in console.

    I think this issue caused by Assembly Name changes that contains `Playables`. (AssetBundle could not follow changes with AssemblyName)

    Does anyone know a workaround for this issue?

    Have you rebuilt the asset bundles with 2019.1?

    Thank you replying !

    I just re-building AssetBundles with 2019.1 now.
    It seems to be working properly.

    But I want to work without rebuilding.

    Is there any other way than rebuilding?

    No, unfortunately. The timeline assets themselves need to be upgraded by the unity editor in order for them to be compatible at runtime.
