Now that we have created the appropriate classes, we need to define them in the Levels we created initially
Open the LobbyMap and in the World Settings, define the lobby game mode
Drag your lobby player starts into the world, the amount that exists in the world here must match the player max you've defined in the lobby project settings.
We've also added a point light, deleted the spotlight, player start, and player character, and added an unbound post processing volume to clamp the min/max of the auto exposure.
The design of your lobby is of course, completely up to you. Just make sure you add the appropriate player starts for the selected settings. If you are free roaming in the lobby, a base engine player start will suffice.
Open the MenuMap and under World Settings, define the Menu Game Mode we created.
Open MyWorld and under World Settings, define the gameplay game mode we created.
