The main thing in a multiplayer map is the Room Manager script - it responds to everything that happens on it. To add it in a scene go to [Game Object -> USK -> Room Manager].
In this tab, you should set all spawn zones, which you've created for this map.
First array for game modes without teams, the second one for game modes with them.
If you will use a scene with the modes in which the Match Target is the Point Redemption value. You should create domination points in the scene and set them in the script.
Domination Points are needed for modes in which the Points Count parameter is 3.
Hard Points are needed for modes with the 1 Points Count. In this case, points will be activated in turn (during the game, it'll look like one point change its position).
The Default Camera is the main camera on a map. It used for the loading screens, game over menus, etc.
Spectates Cameras are needed for the game modes in which the Use Respawn parameter is not active. In this case, characters won't be respawned and players can watch for others.
