public bool enableGPUInstancing;


Enables GPU Instancing on platforms that support it.

To use GPU Instancing to render a Particle System, the particle must use a Shader that contains a Procedural Instancing pass (that is, it contains the #pragma instancing_options procedural directive).

using UnityEngine;
using System.Collections;
public class ExampleClass : MonoBehaviour
    private ParticleSystem ps;
    private ParticleSystemRenderer psr;
    private bool enableGPUInstancing = true;

void Start() { ps = GetComponent<ParticleSystem>(); psr = GetComponent<ParticleSystemRenderer>();

psr.renderMode = ParticleSystemRenderMode.Mesh; psr.SetMeshes(new Mesh[] { Resources.GetBuiltinResource<Mesh>("Capsule.fbx"), Resources.GetBuiltinResource<Mesh>("Cube.fbx"), Resources.GetBuiltinResource<Mesh>("Sphere.fbx") });

psr.sharedMaterial = new Material(Shader.Find("Particles/Standard Surface")); }

void Update() { psr.enableGPUInstancing = enableGPUInstancing; }

void OnGUI() { enableGPUInstancing = GUI.Toggle(new Rect(25, 45, 200, 30), enableGPUInstancing, "Enabled"); } }
