根因分析
Unity的纹理导入器不支持佳能CR2原始图像格式；它期望标准格式如PNG、JPG、TGA或EXR。
English
Unity's texture importer does not support Canon CR2 raw image format; it expects standard formats like PNG, JPG, TGA, or EXR.
官方文档
https://docs.unity3d.com/Manual/ImportingTextures.html解决方案
-
使用外部工具如Adobe Photoshop、GIMP或ImageMagick将CR2文件转换为支持的格式（如PNG、JPG或EXR）。命令示例：magick convert photo.cr2 photo.png
-
如果需要原始图像用于高动态范围，转换为EXR或HDR格式而不是PNG/JPG以保留数据。
-
使用自定义导入器或脚本，通过第三方库（如LibRaw）在运行时加载CR2文件，完全绕过Unity的导入管线。
无效尝试
常见但无效的做法:
-
98% 失败
Renaming does not change the internal file format; Unity will still attempt to decode the raw data and fail with a similar error.
-
90% 失败
Unity does not use system codecs for texture import; it relies on built-in decoders for supported formats only.
-
95% 失败
Re-saving in the same format does not change the encoding; Unity still cannot decode it.
