Ok, I now understand how the events are triggering.
Also note that when the matinee animation is looping, the “Finished” node event will always not fire, because it is always active until something tells it to stop looping.
So all I have to do is to use the “Event” I set in the Event track of a group/groups, and trigger from there for looping matinee animations.
Thanks again for your help.
Edit:
You cannot move the entire animation in a matinee, move it to another place, and then play the matinee animation at that location. It is just not possible.
Instead, I have to use this automation blueprint method so that I can randomly place animations around the map as it finishes.
