根因分析
项目资产的 .meta 文件丢失或损坏，通常是由于 Unity 外部的文件操作或版本控制冲突导致。
English
A .meta file is missing or corrupted for a project asset, often due to manual file operations outside Unity or version control conflicts.
官方文档
https://docs.unity3d.com/Manual/AssetDatabase.html解决方案
-
通过在项目窗口中选择资产并单击“资产 > 重新导入”或按 Ctrl+R 来重新生成 .meta 文件。
-
使用“资产 > 全部重新导入”选项重新生成项目中的所有 .meta 文件。
无效尝试
常见但无效的做法:
-
Delete the asset file and re-import it from the original source.
35% 失败
This may not regenerate the .meta file correctly if the asset is re-imported with the same GUID conflicts.
-
Copy a .meta file from another asset and rename it.
75% 失败
Each .meta file contains a unique GUID; using a duplicate can cause GUID collisions and further errors.
