最近在做动态加载读取外部模型的功能使用了triLib插件，废话不多说直接干货。
第一步下载导入插件，直接分享主打白嫖共享，不搞花里胡哨的。

导入后第一步新建一个管理渲染管线的文件

第二步建立一个渲染管线的文件，放入上一个创建的文件中



配置完成后新建一个文件夹需要把文件和贴图放在同一文件夹内

注意添加后缀名称，

然后抄一下demo代码 有兴趣的可以去研究demo 我是为了快速实现就不细讲了

using System.Collections;
using System.Collections.Generic;
using TriLibCore;
using UnityEngine;
using System.IO;


public class GetLoadFbx : MonoBehaviour
{
 

    //文件路径要加载的模型的绝对路径，不能为空
    string modelFilename;
    [Header("模型贴图必须在同级目录，会自动读取原始模型的使用贴图")]
    //文件名称
    public string name;
    public SetUV GetSetUV;//这个可以忽略
    public AssetLoaderOptions options;//这个就是你创建管理渲染的物体
    void Start()
    {
        GetSetUV=GetComponent<SetUV>();
        modelFilename = Application.dataPath + "/GetModel/Model/SAST5000/";
        LoadNameModel(name);
    }

    void LoadNameModel(string name)
    {
       modelFilename += name;
       AssetLoader.LoadModelFromFile(modelFilename, OnLoad, OnMaterialsLoad, OnProgress, OnError, null, options);     
    }

    /// <summary>

    private void OnError(IContextualizedError obj)
    {
        Debug.LogError($"An error occurred while loading your Model: {obj.GetInnerException()}"); //加载模型时发生错误
    }

    /// <summary>

    private void OnProgress(AssetLoaderContext assetLoaderContext, float progress)
    {
        Debug.Log($"Loading Model. Progress: {progress:P}");
    }

    /// <summary>

    private void OnMaterialsLoad(AssetLoaderContext assetLoaderContext)
    {

    }

    private void OnLoad(AssetLoaderContext assetLoaderContext)
    {
        Debug.Log("Model loaded. Loading materials.");
    }

    void Update() 
    {
    }
  
}
