自动生成材质的思考

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

public class BuildMaterial : UnityEditor.AssetModificationProcessor
{

    //生成出的Material的路径
    private static string MaterialsPath = "Assets/Resources/Skin/";

    // 创建菜单按钮，手工调用创建材质
    [MenuItem ("HETools/BuildMaterials")]
    static void CreateMateral ()
    {
	//获取物体列表
        Object[] selectObject = Selection.objects;

        List<string> path = new List<string> ();

	//从物体列表中获取资源路径
        foreach (Object obj in selectObject) {
            path.Add (AssetDatabase.GetAssetPath (obj));
        }

	//将路径赋给CreateOneMateral函数以创建材质
        foreach (string p in path) {
            CreateOneMateral (p);
        }
        System.GC.Collect ();
    }

    // 监控assets资源添加，发现指定目录ThemeTile有新增加的texture，就自动生成材质
    public static void OnWillCreateAsset (string path)
    {
        int index = path.LastIndexOf (".");
	//返回文件类型
        string file = path.Substring (index);
	//提取路径的单独文件名称
        string[] pathArr = path.Split ('/');
	
	//判断是否为指定资源文件夹
        if (pathArr [pathArr.Length - 3] != "ThemeTile")
            return;

	//将路径赋给CreateOneMateral函数以创建材质
        CreateOneMateral (path);
        System.GC.Collect ();
    }

    // 创建材质球
    static void CreateOneMateral (string p)
    {
	//替换后缀名
        p = p.Replace (".meta", "");
        Debug.Log ("CreateOneMateral from path: " + p);


        int pos = p.LastIndexOf ('/');


        if (pos == -1)
            return;

        string[] strArr = p.Split ('/');

        string themeIDStr = strArr [strArr.Length - 2];

        Texture textur = (Texture)AssetDatabase.LoadAssetAtPath (p, typeof(Texture)) as Texture;//加载材质贴图

        string name = strArr [strArr.Length - 1];

        int y = name.IndexOf ('.');
        name = name.Substring (0, y);
        Material mater = new Material (Shader.Find ("Mobile/VertexLit"));//新建材质并选择相应的着色器
        mater.mainTexture = textur;//将贴图放到材质上

        AssetDatabase.CreateAsset (mater, MaterialsPath + themeIDStr + "/" + name + ".mat");//新建材质资源
	Debug.Log(AssetDatabase.GetAssetPath(mater));
    }
}

这个并不能实现自动生成材质，但是不知道代码问题在哪，有哪位大佬知道能帮帮忙吗？这个代码也不是我自己写的，是在网上复制某一个大佬的。
