I’m trying to trigger an event from my blueprint in a level sequencer. I would like to press the spacebar in my level sequencer and for the blueprint to be “activated” - just like when I click play in the toolbar.
Here’s a little context: I have a blueprint that changes morph targets’ values according to the frame sequence generated from an audio file, it all starts from the first node “Event BeginPlay”. When I click play in the toolbar, it all works perfectly well.
I’ve tried creating trigger events, repeater events, recording the scene after pressing play… I feel like I’ve tried everything! All I managed to do is create a custom event that can trigger one of my morph targets to be set to 1, but when I play it in the level sequencer, it’s not triggered at the correct time and it doesn’t even work systematically.
My goal is to be able to “play my blueprint” in my level sequencer, and I’m surprised at how difficult it is. I naively thought I could trigger an event that would replace the “Event BeginPlay” in my blueprint. There must be something I am not understanding. Any tips?
Thanks for your quick reply! Unfortunately I’ve tried this several times and it doesn’t work. It kind of worked when I create one event that was just in charge of setting a morph target’s value to 1, but when it comes to triggering the entire BP it does nothing at all…
It works when you click play in the toolbar, yes, same here But does it work on your side when you press the space bar to play it in the level sequencer? It doesn’t for me, even if I ticked ‘call in editor’.
I still don’t fully understand which way you want this to go.
Do you want to Start the Level Sequencer when pressing Spacebar, or have an Event inside the Level Sequencer which Starts some Timeline inside a Blueprint?
Hi! I’d like to press the space bar and have the blueprint activated in my level sequence (so your 2nd option). (Basically my BP evaluates moprh targets’ values in function of an audio file)
So I’ve been playing around with Oculus Lip Sync’s playback blueprint, that might give your more info. I’d like to trigger their event OnVisemesReady but the option doesn’t even exist…
Thanks!! I had a look and will give it a try, but from what I see, the events are triggered when the person hits play in the toolbar. I’m hoping it works when pressing space and playing the level sequencer too
If this is not implemented in this Video.
What I did was add the Spacebar to play the sequence via the Level Blueprint - if that is an Option for you.
For this you will have to initialize your Sequnce via Begin Play in the Level BP: So:
Begin Play → Create Level Sequence Player → Save the output as a variable
Then Add the Spacebar and call Play with Movie Scene Sequence Player as your target. Then pipe in your Variable. Works fine for me.

I’ll give it a try! I managed to play the level sequence from my BP but didn’t have the idea of doing it in the level blueprint and then calling “play” with the sequence player. Thank you
I would like to be able to track the blueprint’s animation in the level sequencer. The issue is, my blueprint doesn’t create an actual animation, it just fiddles around with morph target values.
thanks for trying to help though! really appreciate it
