I have developed a game using unreal engine with blueprints. So, is there any option to package the whole project in a “.appx” bundle rather than a few folders and a “.exe” file?
hello!
Did you manage to do this?
I managed to package an .appx via the Windows SDK tools, BUT there are problems when I try to sign it with a self-signed certificate. I used a procedure that has been proven to work for other apps I’ve made in the past, so there’s likely something unreal specific that isn’t working here.
When I got stuck with this, I started experimenting with INNO Setup, to create an installer, and then package that installer .exe as an .appx or .msix - so far no luck and only cryptic error messages with error codes that the Microsoft documentation don’t even list.
I also use blueprints only.
If anyone has solved the whole chain I’d be happy to know how 
Not sure if it’s of any help to you, but packaging the .appx was done via command line by creating an AppxManifest.xml file in the same folder as the output generated from the “package” command inside Unreal Engine, then running:
.\makeappx.exe pack /o /d <path to the unreal engine output folder\Windows> /p
Since I couldn’t sign it, I don’t know how valuable my AppxManifest.xml contents are? I can post them if you’re interested…
