Multiplayer Shootout Network Problems

Development Programming & Scripting Blueprint

Hello Everybody,

I get a black screen and nothing happens in the unmodified “Multiplayer Shootout” example when I hit play after building the program using the “Launch” button in the top right of the editor. I hit launch and the menu comes up fine, but when I hit “Play” I get nothing but a black screen and the warnings seen below in the log.

Warnings:

Anyone can try this. Just download the “Multiplayer Shootout” template from the Learn tab, create a project using the template, and then hit the “Launch” button at the top right of the editor.

Why can’t I connect when launching the project on my computer?

Any help is much appreciated,

@Ryan Gerleve answer at the bottom of this post here helped clear things up for me. Apparently the “Launch” button only cooks the current level that is open. You need to “Package” the project to get full functionality of all the levels.
