在PC上开发时,其天空盒的效果很好,但是为Android平台Build之后,其效果简直没法看。
更为恼火的是,之后PC上的纹理效果也变差了,新加入的纹理效果都会变差,看其纹理格式,使用ETC进行了压缩。
Edit->Preferences...
当选择此选项之后,每当导入新的纹理(无论是拖入或在文件管理器中copy),Unity3D都会根据当前平台的设置进行自动转换,此纹理转换,并不是把纹理文件进行修改,纹理文件是不动的,而是增加了一个.meta文件(如Sunny4_back.tif对应Sunny4_back.tif.meta),其中定义了很多与纹理相关的参数,其中决定此纹理格式的参数为:textureType,此文件内容如下:

1) 选中纹理,纹理的Inspector窗口如下图所示:
上图显示的为Default设置,若Android平台没有单独设置, 则此纹理在Anroid平台采用默认设置,若Android平台单独设置了,则采用Android平台设置的格式。Unity3D只能设置三种纹理格式:Compressed、16bits、Truecolor,若要设置其它纹理格式,则Unity3D无能为力。
把ChangeTextureImportSettings.cs放于Assets/Editor目录下,ChangeTextureImportSettings.cs内容如下:
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! :-)

以上代码参考:Unity3d:批量修改贴图导入设置工具脚本
然后,Unity3D界面如下:
在Project窗口中选中需要设置的纹理(可多选),然后点菜单命令执行对应的转换即可。
