Placeholder Camera
Placeholder Cameras are Actors with a SpringArmComponent and a Camera that can be placed in the level to help preview the point of view of the Universal Camera.

You can modify the Zoom level of the Placeholder Camera using its Target Arm Length.

You can place a PlaceholderCamera and use its Location, Rotation and Zoom as references.

In this example from my Level Blueprint, I move my UC to the point of view of the Placeholder Camera.

note
You can also use Camera Travel to travel to the point of view of a Placeholder Camera.
