Player Camera Manager
The PlayerCameraManager is an important aspect of Unreal Engine and good documentation around it is somewhat sparse. This page exists to try and remedy that.
Creating a shared camera for multiplayer games
This tutorial will show you how to create a shared camera for multiplayer games. Examples for popular games using a similar system are the Lego games or the Smash Bros. games where all players are on the screen simultaneously and the camera reacts to the player positions by moving and zooming. The tutorial will focus on a two character system but the blueprints can be easily adapted to support as many players as desired.
