Seems like the effect is multiplied by a lot, it even makes the game lag when the effect is triggered. I played with the VFX Creator options, but they don’t change anything since the emitter is replaced with a custom one.
Yes, by changing the emitter in the device’s niagara component. It’s pretty much the only way I found to trigger an effect on and off. The enable during phase event works.
Anything in Devices/Legacy folder is not officially supported atm, just keep in mind. Drop in your scene a niagara particle, then hook it up to a sequencer and control its System through it. VFX Creator is a legacy device atm
