I know you can get the vertical field of view by doing workspace.CurrentCamera.FieldOfView. But is there a way to get the horizontal FOV? Or is that the same?
Yes, this is actually the same thing. FOV is only displayed as the total amount of how much you can see rather than just how much of a direction you can see. I don't think there's actually anything that would change that. Just keep doing what you're doing.
If you have any questions or issues, please contact me. ;)
