unity3d纹理格式设置-创新互联
将Texure Type设置为Advanced时纹理的格式列表
| |
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! :-)
//
