Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

[Fatal Error] Error During cooking prevents package building

For background this is a Uni project that multiple people have been working on across source control, we've used 12.5 from the start without changing, we have successfully packaged before 2 months ago, we've isolated the build while testing and tried the existing forum problem solutions, checked the ini files, deleted unnecessary content, rebuilt lighting, deleted database, changed project settings, changed packaging paths, same issue has occurred over multiple machines.

Thanks in advance and the error log is attachedlink text

Hey Arkane30,

So I'm seeing this error in your logs: [2017.03.28-13.40.24:470][316]MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: [2017.03.28-13.40.24:465][ 0]LogWindows:Error: === Critical error: ===

 [2017.03.28-13.40.24:470][316]MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: 
 [2017.03.28-13.40.24:470][316]MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: Fatal error!

Unfortunately, there's not much information to go off of there, but it appears you may be experiencing some sort of ensure or commandlet crash that isn't producing a callstack in your logs.

One thing I can recommend is to try updating a copy of the project to a later version to see if there is some issue with the engine that has since been resolved.
