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"

Change the engine version of a project via command line?

I know that it's possible to change the target engine version of a project via the launcher, or by right-clicking the .UProject file and selecting "Switch Unreal Engine version..." from the context menu.

Is there any way to call this functionality from the command line?

Product Version: UE 4.8

  • Solution 1: Make a script that calls 'UnrealVersionSelector.exe /switchversion FOLDER_OF_THE_PROJECT'. This binary, on my installation is located in C:\Program Files (x86)\Epic Games\Launcher\Engine\Binaries\Win64\ . The problem with this solution is it will pop-up the dialog to ask you which version you want to use.

  • Solution 2: Make a script that open your .uproject, change the line "EngineAssociation": "4.9" by the version you want, and then regenerate your project files using 'UnrealVersionSelector.exe /projectfile FOLDER_OF_THE_PROJECT'. This solution doesn't pop any dialog.
