ParticleEmitter trigger on demand

Hello,

My use case is that when a rigidbody detects a collision, I want a ParticleEmitter to trigger only once (like an explosion effect) and then stop by itself instead of triggering continuously until the node is removed. Is there a trigger on demand for particle emitters?

Also setting AutoRemoveMode doesn’t seem to do anything for me for some reason, in either the editor or my project.

Do you set “Active Time” attribute for PartitionEffect other than 0?
Usually I just clone “prefab” with needed partitions and set AutoRemoveMode.

Thanks! I never set an Active time before, that seems to work now as intended.
