I understand this is probably by design to be efficient, but is it possible to expose CanCompileClips() to public so that we can create a TrackMixer for our custom TimelimeTrack even when there is no clips? Or is there another way of doing this? We are trying to make our track mimic the behaviour of ActivationTrack i.e. run some disable logic from the mixerPlayable when there's nothing on the track. Thanks Edit: I tried implementing my disable logic in GatherProperties as a workaround, which does the job in the editor, but won't work in the build or play mode.
