Split screen function is used to manage the view mode of scene window. Currently, it only supports layering multiple layers in a scene and displaying two viewports in split screen. The specific operation steps are as follows:

1. First, in Unreal Engine - Project Settings - Project - Maps and Mode , set the local multiplayer - two-player split screen layout to vertical.



2. Run the setup scene.
3. Click the Scene - Split Screen button to switch to the Split Screen Settings panel.
4. Click Open Split Screen to display the layers in the current scene in two viewports. You can check the layers displayed in each viewport through the viewport selection list. By default, all are checked.

The split-screen display effect is as shown in the figure below.
