public bool enableGPUInstancing ;

描述

在支持 GPU 实例化的平台上启用 GPU 实例化。

为了使用 GPU 实例化渲染粒子系统,该粒子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"); } }
