Unity导入模型和材质丢失问题处理(大批量操作)

在unity资源商店买的模型包,导入unity后,全部材质丢失,稀里哗啦乱成一片
在网上搜了下材质丢失的办法,结果都是一个一个手动操作
窝草,资源包里接近两万个资产,手动不是要撸的灰飞烟灭
遂自制自动解决材质丢失办法

用法很简单粗暴
右键点击选着要更改的文件夹,

点击 easywork==>改变选中文件夹下所有材质为Standard

点击 easywork==>统一模型材质名称
如下,直接上代码

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


public class 找回丢失材质
{
    private static string shaderMode = "Standard";

    [MenuItem("Assets/阿飞的EasyWork/改变选中文件夹下所有材质为Standard")]
    /// 

    /// 改变选中文件夹下所有材质为标准的
    /// 
    public static void ChangeMaterialsMode()
    {
        string rootpath = GetSelectFilePath();
        foreach (var path in GetAssetsPathWithFormat(rootpath, "mat"))
        {
            modificationMaterialMode(path);
        }
    }

    [MenuItem("Assets/阿飞的EasyWork/统一模型材质名称")]
    /// 

    /// 改变选中文件夹下所有材质为标准的
    /// 
    public static void click1()
    {
        string rootpath = GetSelectFilePath();
        foreach (var path in GetAssetsPathWithFormat(rootpath, "fbx"))
        {
            modificationFBX_Name(path);
        }
        foreach (var path in GetAssetsPathWithFormat(rootpath, "FBX"))
        {
            modificationFBX_Name(path);
        }
        AssetDatabase.Refresh();
    }



    public static void modificationFBX_Name(string path)
    {
        if (string.IsNullOrEmpty(path))
            return;
        ModelImporter mode = (ModelImporter)ModelImporter.GetAtPath(path);

        if (mode != null)
        {
            mode.materialName = ModelImporterMaterialName.BasedOnModelNameAndMaterialName;
            AssetDatabase.ImportAsset(path);
        }
        else
        {
            Debug.LogError("设置模型材质名称失败 : " + path);
        }
    }

    ///

ok
