ParticleSystemRenderer.enableGPUInstancing

描述

在支持 GPU 实例化的平台上启用。

为了使用 GPU 实例化渲染粒子系统，还必须使用包含程序实例化通道的着色器（即，它包含 #pragma instancing_options procedural 指令）。

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");
    }
}
