The sequencer is “MultiBinding” a large number of BP actors, including the Niagara FX, and keying parameters such as FX strength.
I would like to have this large number of BP actors already lined up in the scene, and when a Box actor (that is keyed to move in the sequencer) is hit, I would like to activate the BP actor in that position. (The goal is that they will hit in sequence and it will look like a wave)
Instructions or a tutorial would be helpful.
