ALS and Sequencer?

I’m trying to use the Sequencer to create cutscenes, standalone and in-game, cutscenes with Sequencer.

The core animations come from ALS (Advanced Locomotion System), so I first add the ALS_Aninman_Character, then CharacterMesh0, which I add animations from.

The animations appear in the timeline, but they don’t animate.

They can animate if I use ‘Custom Mode’ and not ‘Animation Blueprint’ in the Animation Mode.

I saw the official docs said not to use ‘Custom Mode’ when doing cutscene / gameplay transitions.

Blend Gameplay Animation to Cinematic Animation in Unreal Engine | Unreal Engine 5.4 Documentation | Epic Developer Community (epicgames.com)

That can explain all the crashes I got when I tried to play the game with cutscenes with “Custom Mode”.

Longwinded context, but was hoping someone could point me in the general direction of “think of this”, “Do’s and Don’ts”.
