Niagara Fluid Plugin Collision Event GPU

i want to kill the particles after colliding the Z- boundary wall.
I cant create a collision event cause all the niagara fluids are GPUSims so this isnt possible.
Is there a way to fix this?
The goal would be to set a collision box that kills the particles when they collide.
The box would be hidden in game.

The solution to open Boundary -Z dont work for me.

Hope you can help me out :slight_smile:
