#Particle systems in baked prefabs

If I have a prefab that contains a particle system, what's the best way to get access to that system and modify it at runtime?

I'm not doing anything special to bake the prefab, just calling GetEntity in the baker. The particle system exists and works in the game, and there's obviously some sort of link to it from the prefab entity, but I can't figure out the syntax to get access to the particle system.

SystemAPI.Query<SystemAPI.ManagedAPI.UnityEngineComponent<ParticleSystem>>() works to find all the particle systems in the world, but I seem to only have read-only access to them. What I really want is the ability to modify a particle system that exists on a single known entity.

it's an actual game object instance

so feel free to modify however you want

Nothing I tried seemed to affect the actual in-game particle system so I assumed it was either ECS doing its read-only access thing or that I was modifying a prefab rather than the instance. I'll experiment some more.

#

Yep, I just forgot to use ParticleSystem.Clear() as well as ParticleSystem.Stop(). Is there a way to get a particle system from a single entity or do I need to just query everything and filter it?

I had similiar setup

#

I would just pass some id/entity associated with particle sstem

#

from jobs

#

and then on main thread just get that system and emit all particles
