How can i make an animation starting the level?

you may be able to set this up in the Mantinee system, I have limited experience with it but I’m pretty sure you can tell it to “attach too” either the actor or a bone.

Look into the Construction scripts in blueprints. Drag your actor into the scene, open the level blueprint and on play - Get matinee camera Get Player actor, set up an attach too component.

Here is another post with a similar workflow that could work for you.
