Play particle system

I instantiate a prefab as a child of a hybrid game object and then why I start the instance with particle system nothing happens?? Any idea what I am doing wrong? I see the cline as a child in the scene but it doesn’t trigger when I want to.

Hybrid renderer 0.9 added support for particle system(i believe). Just letting you know.

Basically, conversionSystem.AddHybridComponent(comp) will do the job.
But for ParticleSystem there is one extra hidden component ParticleSystemRenderer

HybridComponent Tool

using Unity.Entities;
using UnityEngine;
using System.Collections.Generic;
using System.Linq;
    [DisallowMultipleComponent]
    [RequiresEntityConversion]
    public class HybridComponent : MonoBehaviour, IConvertGameObjectToEntity
    {
        [SerializeField] protected List<UnityEngine.Component> Components = new List<Component>();

        public virtual bool IsNativeSupported(Component comp) =>
            comp is Transform ||
            comp is MeshRenderer ||
            comp is MeshFilter ||
            comp is SpriteRenderer ||
            comp is UnityEngine.VFX.VisualEffect ||
            comp is IConvertGameObjectToEntity ||
            comp is ConvertToEntity ||
            comp.GetType().Name.Contains("Authoring");

        protected virtual void Reset()
        {
            Components.Clear();
            foreach (var comp in gameObject.GetComponents<Component>())
            {
                if (IsNativeSupported(comp)) continue;
                else Components.Add(comp);
            }
        }

        private void OnValidate()
        {
            if (Components.Any(c => c is ParticleSystem) && Components.All(c => !(c is ParticleSystemRenderer)))
            {
                var renderer = GetComponent<ParticleSystemRenderer>();
                if (renderer != null) Components.Add(renderer);
                else Debug.LogError("ParticleSystem referenced but ParticleSystemRenderer is missing!");
            }
        }

        public void Convert(Entity entity, EntityManager dstManager, GameObjectConversionSystem conversionSystem)
        {
            foreach (var comp in Components)
            {
                if (!comp) continue;
                if (comp is SkinnedMeshRenderer) continue;
                if (comp is Animator) continue;
                conversionSystem.AddHybridComponent(comp);
            }
        }
    }

Reset HybridComponent will trigger a new search for potential Components

UnityEngine.VFX.VisualEffect is the new way of doing FX, It will be made HybridComponent by default.
That’s probably why ParticleSystem is not made HybridComponent automatically.

@Lieene-Guo Thank you so much for your answer here. This would have wasted an insane amount of my time if not for your pro-tip about the ParticleSystemRenderer. Cheers.
