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: // http://forum.unity3d.com/viewtopic.php?t=16079&start=0&postdays=0&postorder=asc&highlight=textureimporter// // Developed by Martin Schultz, Decane in August 2009// e-mail: ms@decane.net//// Updated for Unity 3.0 by col000r in August 2010// http://col000r.blogspot.com//// /////////////////////////////////////////////////////////////////////////////////////////////////////////public class ChangeTextureImportSettingsUnity3 : ScriptableObject{    [MenuItem("Custom/Texture/Normal Format")]    static void NormalFormat()    {        ChangeTextureFormat_AutoTruecolor ();
