格式

详解

Automatic Compressed

压缩RGB纹理，默认选项，常用的漫反射纹理格式。4位/像素(32KB, 256x256)

RGB Compressed DXT1

压缩的RGB纹理。常用的漫反射纹理格式。4位/像素(32KB, 256x256)

RGBA Compressed DXT5

压缩的RGBA纹理。是漫反射和高光控制纹理的主要格式。1字节/像素(64KB, 256x256)

RGB Compressed ETC 4bits

压缩的RGB纹理，是Android工程默认的纹理格式，不支持alpha通道。(32KB, 256x256)

RGB Compressed PVRTC 2bits

压缩的RGB纹理，支持Imagination PowerVR GPU2位/像素 (16KB, 256x256)

RGBA Compressed PVRTC 2bits

压缩的RGBA纹理，支持Imagination PowerVR GPU2位/像素 (16KB, 256x256)

RGB Compressed PVRTC 4bits

压缩的RGB纹理，支持Imagination PowerVR GPU4位/像素 (32KB, 256x256)

RGBA Compressed PVRTC 4bits

压缩的RGBA纹理，支持Imagination PowerVR GPU

4位/像素 (32KB, 256x256)

RGB Compressed ATC 4bits

压缩的RGB纹理，支持Qualcomm Snapdragon,4位/像素 (32KB, 256x256)

RGBA Compressed ATC 8bits

压缩的RGB纹理，支持Qualcomm Snapdragon,8位/像素 (64KB, 256x256)

Automatic 16bits

RGB彩色，16位彩***最多可以有2的16次方种颜色(低质量真彩色)

RGB 16bits

65万色不带alpha，比压缩的格式使用更多的内存，适用UI纹理(128KB,256x256)

ARGB 16bits

低质量真彩色，具有16级的红绿蓝和alpha通道(128KB, 256x256)

RGBA 16bits

Automatic Turecolor

高质量的真彩色，也就是32位的色彩(256x256的纹理大小为256KB)

RGB 24bits

真彩色不带alpha通道(192KB, 256x256)

Alpha 8bits

高质量alpha通道，不带颜色(64KB, 256x256)

ARGB 32bits

真彩色带alpha通道(256KB, 256x256)

RGBA 32bits

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：

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! :-)

//
