Unity报错：This MeshCollider requires the mesh to be marked.....

运行或者打包时候报错：This MeshCollider requires the mesh to be marked as readable in order to be usable with the given transform.

解决方法：开启Meshes的读写

可以写一个批量处理的脚本：

using UnityEngine;
using UnityEditor;
using System.IO;

public class FixModel
{
    [MenuItem("Tools/FixModel")]
    static void Fix()
    {
        var fs = Directory.GetFiles(Application.dataPath, "*.FBX", SearchOption.AllDirectories);
        foreach(var f in fs)
        {
            var path = f.Replace(Application.dataPath, "Assets");
            var imp = AssetImporter.GetAtPath(path) as ModelImporter;
            if(null == imp)
            {
                Debug.LogError(Path.GetFileName(f) + " is not a Model");
            }
            else
            {
                if(!imp.isReadable)
                {
                    imp.isReadable = true;
                    Debug.Log("fix " + path);
                    imp.SaveAndReimport();
                }
            }
        }

        AssetDatabase.Refresh();
    }
}
