Niagara Death Event

It appears the death event in Niagara for v4.23 is not functioning correctly unless I’ve missed something. It does not cause other emitters to trigger.

Create two default emitters, looping spray, omnidirectional burst.
Create a system housing both of these. add generate death event on looping emitter. add event handler properties to omnidirectional as well as receive death event.

Result: Omnidirectional plays once in the center and deaths of the looping particle do not cause more to spawn.

I was following this very long tutorial video but I just could not get it to work like he did: Niagara Events and Updating Emitters via Blueprint - Intro to Niagara Pt. 2 - YouTube

Is this broken in 4.23?

It’s an old question but since I lost a bit of time on this recently here is the solution:

  • remove the spawn burst module of the fountain emitter, the spawn count should be set on the event handler properties module + that’s the reason why the emitter plays once in the center
  • set loop behavior to infinite on the emitter state so it can process incoming events continuously
