Markers and Signal Emitters not working when Timeline in Manual Update Method ?

I know t$$anonymous$$s question was from a w$$anonymous$$le ago, but t$$anonymous$$s was the first $$anonymous$$t that shed some light on the issue I was having.

It is possible to get around t$$anonymous$$s limitation if you have the Timeline package embedded in your project, as we have. In TimeNotificationBehaviour.cs the check that stops Signals emitting is at the beginning of TimeNotificationBehaviour.PrepareFrame():

 if (info.evaluationType == FrameData.EvaluationType.Evaluate)
 {
       return;
 }

You could either remove t$$anonymous$$s completely, leading to Signals emitting during scrubbing behaviour, or surround in an 'if (!Application.isPlaying)' check to retain the existing scrubbing behaviour but enable Signals when actually playing the game and using manually-updated Timelines.

Yes, that is by design.
