UE4 - Can I make GPU particles emit on events?

General Discussion
#1

I am working in UE4.

Do GPU particles work with Event Generators?
For example I have GPU rain and once it collides it emits a GPU splash?

I have been able to get it to work with CPU particles but not GPU particles even though the modules exist for GPU type particles.

you can spawn gpu particles on events, but they can’t generate events.
