What's the best way to communicate from Level BP to Anim BP?

I have a Matinee Event that fires and starts an event in the level blueprint. This event should update a variable that gets sent / read by an animation blueprint to trigger some changes.

I dont see any way to communicate from the level blueprint to the animation blueprint directly. Am I missing something?

Without being in front of the engine, you could cast from the Level BP to the player character / player controller and from there cast to the AnimBP. There might be another way but that’s what I would suggest without being in front of the engine.
