Hey all,
So I have an actor with a particle system in it. At some point the actor is set to hidden in game. When it is set to being visible again, the particles do not reappear. I looked into this briefly and found someone else with a similar issue, but I couldn’t resolve it. Even if I set the actor back to hidden and spawn a new particle system, that new one also does not show up. Any ideas?
can be a variety of things (in these cases its always handy to supply screenshots of the blueprints and emitters).
did you re-activate the emitter in the blueprint?
Is the emitter set to be killed on completion or Kill on deactivate?
play around a bit with these settings and see if you can get the emitter back to life 
Ah! Found the problem. I was reactivating the particles correctly, but I was doing it the frame before the actor they’re in became visible again, so even though they were activated, they instantly deactivated and were hidden again. I just fixed the ordering and that worked.
Also, I had to hit the “reset” checkbox on the Activate node to reset the hidden in game status.
Luos, I love your particle videos and I actually have a few super quick questions about particles. Would you be able to help me answer them?
sure, though this is not the place for that.
