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"

Unknown packaging failure - silent failure with no exe

Hi, I'm building a mac and pc project and have been relying on only blueprint. I've successfully built the project on both operating systems before, but recently my packaging has been failing with an unknown error. Packaging creates the directory but doesn't produce an executable on both mac and pc. If I use the project launcher instead of the menu option, it fails with the following error:

 System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

The only things I can think may have affected it is that I installed the houdini plugin and I installed the 4.22 preview of unreal engine. I made sure to disable the houdini plugin and uninstall 4.22, but it didn't change anything.

I've attached my log files found in the AppData folder for the automator, as well as the uproject text. Any help is much appreciated!

For anyone who has a similar issue, I managed to package my project by migrating to version 4.21. I still don't know why it happened.
