Is there a way to make editors open in a new tab in the same window?

Just in case anyone else comes across this and wants to change the default behaviour for all projects… you can do this…

  • Browse to the installation directory for Unreal Engine 4

  • Open the Engine directory

  • Open the Config directory

  • Open the file named BaseEditorPerProjectUserSettings.ini using Notepad

  • Press CTRL+F5 to perform a search and enter “EditorStyleSettings”
    EditorStyleSettings

  • Within the editor style settings section add the following entry;
    AssetEditorOpenLocation=MainWindow

You can change the “MainWindow” part to any of the other values from the drop down menu in UE4 if you prefer something different.
OpenLocationsEnum

  • Save the file.

All new projects you open will now use this preference.
