Hi,

Your blueprint only contains the positioning of your effect.

You will need to play it via an event, please find in Unreal docs how to do it in the blueprint.
Then you have to pass a trigger value from Aximmetry, on that please consult:

(The video take starting an animation as an example, but the principle is the same.)

The following video tutorial covered this topic
