This Unreal Engine 5.4 video is about packaging a game for distribution.
We start by packaging the project, and talking about how it took 46 videos to talk about this step that should be done early, and often. We then talk about the Cooked folder, which is an easy way to see what’s being included in your package (which is everything in your project, by default). We then shrink the project by only including intended Maps (Which in short means, the huge StarterContent Map is not included). We also talk a little about how Shipping and Development Builds differ (Especially related to Save Games, which in Shipping, go to %LocalAppData%/ProjectName/Saves on Windows).
