批量修改贴图导入设置工具脚本

这个Unity3D批量修改贴图导入设置工具脚本十分小巧，但是威力大。特别针对大批量贴图要调整尺寸等等的时候作用尤为明显。在菜单中添加“Custom→Texture”的方式来批量改变所选的贴图导入设置。Unity本身只能一次打开一张图片进行导入设置，目前这个脚本可以批量更改贴图格式，是否开启MipMap，调整纹理最大尺寸，是否可读等等。

用法是把脚本放在你项目的资源目录的Editor文件夹下。然后选择你要批处理的纹理。到菜单中选择要处理的类型就可以了。

using UnityEngine;  using UnityEditor;         // /////////////////////////////////////////////////////////////////////////////////////////////////////////  //  // Batch Texture import settings modifier.  //  // Modifies all selected textures in the project window and applies the requested modification on the  // textures. Idea was to have the same choices for multiple files as you would have if you open the  // import settings of a single texture. Put this into Assets/Editor and once compiled by Unity you find  // the new functionality in Custom -> Texture.
