Unity3D默认纹理格式问题
1 在导入时是否自动压缩
2 Unity3D设置纹理格式
3 在Unity3D中自定义设置纹理格式
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。
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：

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。

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。

Unity3D默认纹理格式问题
1 在导入时是否自动压缩
2 Unity3D设置纹理格式
3 在Unity3D中自定义设置纹理格式
1. 简介
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。
2. Unity3D默认纹理格式问题
2.1 在导入时是否自动压缩
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：

userData:2.2 Unity3D设置纹理格式
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。
2.3 在Unity3D中自定义设置纹理格式
把ChangeTextureImportSettings.cs放于Assets/Editor目录下，ChangeTextureImportSettings.cs内容如下：[javascript]

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。
