根因分析

纹理使用了目标构建平台（例如WebGL、iOS）不支持的GPU压缩格式（例如DXT1、BC7），导致导入失败。

English

The texture uses a GPU-compressed format (e.g., DXT1, BC7) that is not supported by the target build platform (e.g., WebGL, iOS), causing import failure.

解决方案

  1. In the Inspector, select the texture asset, go to the 'Platform Override' section for the target platform (e.g., WebGL), and change the compression format to a supported one like ASTC (6x6) or ETC2 (RGBA). Example: For WebGL, set Format to ASTC_RGBA_6x6.
  2. If the original .dds file is not needed, reimport the texture as a lossless format (e.g., .png or .tga) and let Unity compress it automatically for the target platform.

无效尝试

常见但无效的做法:

  1. 40% 失败

    Converting the .dds to .png in an external tool without changing compression settings in Unity still fails because the importer detects the original format.

  2. 50% 失败

    Enabling 'Override for WebGL' but keeping the same DXT1 format does not help; the platform override must change the format to ASTC or ETC2.
