I took some time, and I must have made a half dozen or so different versions of the core of the multiplayer course.. I'm always amazed how this one course can be so versatile. As far as I'm concerned, all your courses are required learning for anyone, wanting to get serious about Unreal game dev. 🤜🤛👍

I am going to mention your channel in my next video. I learned quite a bit from your Motion Warping video. I am using it to solve my horse mounting issues in ACF. Not that you need the help, but I think your channel content is great and would help a lot of the people who follow my channel as well. I also just purchased your Udemy course for the C++ shooter ... looks great so far ! Cheers !

In order for EOS actually showing a login screen, you need to provide an encryption key. If you're not publishing through Epic, just provide 0000000000000000000000000000000000000000000000000000000000000000 as your encryption key.

On 5.0.3 - once the plugin is added, my project can no longer compile from source. Restoring the Intermediate, Saved, and Binaries folder, and deleting the plug-in my project works just fine. Going through the process again, I am met with different errors/unfound files in Visual Studio. Have tried on 2019 and 2022 with the same results. I have the Unreal VS plugin installed. There is something broken in this plugin, or a step you are missing from the video.

[@dmitriyborisov4222]

The override of OnLevelRemovedFromWorld only removes the widget from the screen and enables game input mode (MenuTearDown function). You can remove the override and call MenuTearDown from OnCreateSession after ServerTravel for example, and the same in OnJoinSession for the client. Maybe not the best solution but if will fix your problem until we find out what happened to OnLevelRemovedFromWorld.

Yes, replace it with NativeDestruct (a virtual override)
