Shared Timeline Track

Hi,

I am wondering, would it be possible, to have a Timeline Track that is shared among multiple Timeline Assets and kept in sync?

Context:
I am managing character actions with timeline, e.g., attack animations (play animation, play sound, play particle systems, activate hit boxes, etc.). These are becoming numerous and similar. Some tracks are even identical. Currently, they are redundantly setup in every timeline and there is no way to change all of them at once.

Solution Attempts:
So I turned to a custom behaviour that references a ScriptableObject asset with AnimationCurves. But this only works for some cases. The ScriptableObject that I actually want shared is the Timeline Track itself...
I tried creating persistent assets of tracks using the [CreateAssetMenu] attribute. However, when dragging such a track into the timeline window, a track of a different type is created (?!). Also, it will most likely create a new instance anyway instead of referencing the asset.

Any idea is welcome! Thanks

 

Thanks, good idea. That will probably do. Will have to consider the performance impact of additional PlayableDirectors, though.
I can throw in a custom track/playable to also set the timeline asset that is being played. That is something that ControlPlayableAsset could think about doing itself, maybe? The swapping out of TimelineAssets at runtime is a quite powerful feature, I think!
