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"

Failed to open descriptor file for *.uproject

I'm trying to setup a BuildMachine to run a predefined test map. I followed this guide: https://docs.unrealengine.com/latest/INT/Programming/Basics/CommandLineArguments/index.html

The problem is when I try to run "UE4Editor.exe Foo.uproject /Game/Maps/FooMap - game" I get an error message: "Failed to open descriptor file for Foo.uproject"

I can't find any way to figure out the cause of this since it doesn't log anything to console...

Any help?

Hi quintendc,

Which version of the editor are you using? Also, please post your dxdiag (system specs if you're on a Mac).


Also, when you get this error are you only running one version of the editor?
