1、点击游戏对象、点击XR、点击添加XR Origin，并把自带的摄像对象删除
2、添加脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Unity.XR.PXR;//引入xr对象
public class toushi : MonoBehaviour
{// Start is called before the first frame updatevoid Start(){//打开彩色摄像透视模式PXR_Boundary.EnableSeeThroughManual(true);}// Update is called once per framevoid Update(){}
}

3、创建空父对象并赋予刚才写的透视脚本
