Timeline preview does not show in Game window?

Hi all. I am using Timeline to make cutscenes for my game.

I am using Cinemachine Virtual Camera + animator + keyframes to get the desired effects.

The above timeline works fine in Play Mode, the desired zoom in effect works flawlessly.
However, when I hit play in the editor to preview the timeline and fine-tune the cutscene, no changes show in the Game window.

1 of the signal emitters are related to the camera, which toggles a “isInProduction” boolean to true in the Camera Controller script. The Camera Controller then sets the animation state of the CinemachineStateDrivenCamera to “Production” state. The other two are dialogue system triggers and interaction triggers, which should be irrelevant with this issue.

Any help is greatly appreciated, please LMK if clarification is needed!

You mean it works fine the way it is designed in play mode, but any changes you make during play mode are not reflected?

Are you scrubbing the timeline, or do you have a button to restart the timeline playback?

What change specifically doesn’t update during playmode?
