遍历文件夹下的对象，并修改其导入设置：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
using System.IO;
using System.Diagnostics;
using System;
using System.Text;
public class TextureOperation
{
[MenuItem("Assets/Texture/DisableMipmapAndRW")]
static void DisableMipmapAndRW()
{
UnityEngine.Object[] objs = Selection.GetFiltered(typeof(UnityEngine.Object), SelectionMode.DeepAssets);
for (int i = 0; i < objs.Length; i++)
{
UnityEngine.Object obj = objs[i];
Texture2D tex = obj as Texture2D;
if (tex)
{
string texturePath = AssetDatabase.GetAssetPath(tex);
TextureImporter ti = AssetImporter.GetAtPath(texturePath) as TextureImporter;
if (ti)
{
ti.mipmapEnabled = false;
ti.isReadable = false;
ti.SaveAndReimport();
}
else
{
UnityEngine.Debug.LogError("========Fail to batch " + texturePath);
}
}
}
}
}
遍历所选文件夹下的 对象
UnityEngine.Object[] objs = Selection.GetFiltered(typeof(UnityEngine.Object), SelectionMode.DeepAssets);
通过对象，拿到它的路径
string texturePath = AssetDatabase.GetAssetPath(tex);
通过它的路径，拿到它的importer，设置其属性；然后，保存并重新导入。
AssetsProcessor类也能处理对象，然后运行reimportAll也可以好像。
