本文介绍了一个Unity中的脚本，该脚本用于自动调整纹理资源的导入设置。具体来说，脚本会根据纹理是否包含透明通道及纹理尺寸来决定其压缩方式和最大尺寸，从而实现针对不同需求的纹理资源优化。

using UnityEngine;
using System.Collections;
using UnityEditor;
public class ImportModflyTextures : AssetPostprocessor{

    private uint m_Version = 0;
    public override uint GetVersion() {return m_Version;}

    public void OnPostprocessTexture(Texture2D tex){

        TextureImporter importerTexture = (TextureImporter)assetImporter;

        if(importerTexture.DoesSourceTextureHaveAlpha() ==  true){
                if(tex.width >= tex.height )
                    importerTexture.maxTextureSize = tex.width/2;
                else importerTexture.maxTextureSize = tex.height/2;

            importerTexture.textureFormat = TextureImporterFormat.AutomaticTruecolor;
        }else{
            if(tex.width >= tex.height )
                importerTexture.maxTextureSize = tex.width;
            else importerTexture.maxTextureSize = tex.height;

            importerTexture.textureFormat = TextureImporterFormat.AutomaticCompressed;
        }
        //AssetDatabase.Refresh(ImportAssetOptions.ForceUpdate);
    }
