I have a similar issue.
- I have a BP actor added to my Sequencer.
- The BP actor has a “Spawn” custom event that starts a timeline (which animates some spawn effects).
- I’m using a TriggerEvent track in Sequencer, and the event on that track is wired up to trigger Spawn.
- “Call in editor” is selected on the Sequencer TriggerEvent, and on the BP Spawn Event
Spawn is firing, but the timeline doesn’t update. It does work in PIE. I’m guessing this is because Tick doesn’t work without PIE/MRQ?
