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"

Error upgrading project to 4.13

Hey everyone! I have a project I've been working on in UE 4.12.5, but I'm having trouble upgrading it to 4.13

This is the error I get:

Then when I try to open it (it still makes a project file) I get this error:

alt text

And if I try to rebuild, I get this error:

Anyone have any ideas on how to fix this? Looks like it has to do with using steam...

Product Version: UE 4.13

Open your Game's uproject file in a text editor. In your case, I believe this will be:


Inside of that file, look for a "Plugins" JSON array. You'll need to add the OnlineSubsysteamSteam plugin to this array. This will look something like this:

 "Plugins": [
         "Name": "OnlineSubsystem",
         "Enabled": true
         "Name": "OnlineSubsystemUtils",
         "Enabled": true
         "Name": "OnlineSubsystemSteam",
         "Enabled": true

Hope that helps!

Thanks for the reply!

I ended up having to comment out all steam related stuff from my C++ documents and turn on the new steam online system plugin in 4.13 - problem solved!
