Sometimes we want to hide certain areas of a panorama and you can do that now with the Horizontal FOV setting. This setting allows you to hide only parts of the panorama.
To access this you would need to check the panorama tab > Field of View
Here are some basic rules to understand:
The slider sets the minimum / maximum yaw the viewer edge can be at, in degrees.
default Left (minimum yaw): -180
default Right (maximum yaw): 180
Range : -360 to 360
Limits work only when the selected range is less than 360
