UE4 package failed, and the last prompt is “error unknown cook failure”
What’s the reason? Look up the error from the beginning of the log. The suspicious errors found at the beginning are as follows:

The fatal error in the red letter doesn’t explain the specific reason. Continue to look up and see that “the operation is completed successfully”. Don’t be confused by this. Continue to look up and find that one is just packing output, but packing it to the file physmat_ Metal stops, continues the file, and finds that the file can’t be seen in the editor, but exists in the folder. The original file has been covered by an error. Just restore it to the previous version.
In some cases, one of the above knowledge may be the problem of cook, such as the following example:
