Hey how do I open up a demo project for UE4?
Just download it -> go into the folder where you saved the project -> double click onto the uproject file. Or just open it in the launcher
You can click on ‘Library’ in the launcher. You can go to ‘Open New Project’ in the file menu. You can double-click the file in your folder. Keep in mind that some projects have multiple ‘Levels’ which have to be opened using the ‘Open Level’ option in the file menu.
