Hello,
I am currently building a forklift-based cargo transportation environment using Unreal Engine, and I would like to politely ask a question regarding the camera FOV (Field of View) setting.
In my setup, a rear camera is attached to the forklift to capture the rear view, and the captured image is displayed in real time on a monitor by applying the camera output to a Plane using a Material.
As shown in the images below, the system uses a camera and monitor to provide the rear view, so I named it CMS (Camera Monitoring System).
My question is specifically about the FOV setting.
In the ‘SC_CMS_Bwd' Projection settings, I can directly set the FOV value. However, I am not sure whether this value represents a Horizontal FOV or a Vertical FOV.
Additionally, if possible, I would also like to know the reason or basis for your answer, such as:
-
Unreal Engine official documentation
-
Engine behavior or implementation details
-
Calculation methods
-
Tooltip or editor descriptions
Any reliable reference or explanation would be extremely helpful.
Thank you very much for your time and assistance.
