question about level sequence

Let’s say I have an animation of a sword impact in the level sequence and I want the character to freeze in a pose for 3 seconds directly in the level sequence in the middle of the animation, and the question is whether to pause the animation in the level sequence and how to do it

One way of doing it is to create 2 custom event inside your character bp, first one will play attack montage and the 2nd one will do your freeze anim/vfx/fix pose.

In the sequencer, add your character bp, add a track event and add your custom events:

You need to play the sequencer ingame to see the change.
