Niagara is auto destroyed when the actor is destroyed.

[baobao4435]

Hello,great people. I have another question here.
the actor is a projectile.it uses the”spawn system attached”to spawn a smoke tail Niagara and then fly to the player.
But when it hit the player and destroyed itself,the smoke is also gone immediately.it didn’t wait for the smoke particles to complete their lifetime.

I unchecked the auto destroy Box on the “spawn system attached”node.doesn’t work.

I want the Niagara to auto destroy.
But the smokes that already exist don’t disappear immediately.

The video is here.

Can’t see much .but when I increase the lifetime of the smoke ,it will pretty obvious. Imagine that a long tail just disappear in a moment.(all at a time)

How to keep spawned Niagara particles alive after actor is destroyed?

While not niagara, the way we do it with cascade is to disable the actor and delay its “destroy” until the emitter has done its task. so > on hit > disable actor & emitter > delay until emitter is done (trough delay or other means) > destroy. Make sure the emitters (I only have cascade knowledge, but assume its the same) do not have “destroy on deactivate” on. this way when the emitter is deactivated the particles already spawned will do their thing, while no new ones will be emitted.

I found this ,the solution in the topic seems to work.

But I don’t know how I achieve it, because I didn’t discover a node called disable actor.

Please help
