텍스쳐 설정 일괄 변경

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. Enjoy! :-)
//
// Based on the great work of benblo in this thread:
