I want to decrease how far the player can move their head horizontally from left to right.
(The camera is attached to a sphere and has direction forces applied to the right and left thumb sticks, along with some data sources)

The right thumb stick controls the cameras rotation, I managed to restrict the vertical rotation by decreasing the positive and negative values in the generic filters. But I can't get the same result for the horizontal rotation. It means the player can do a 360 head spin..
(seeing their own body, sadly they aren't an owl! or possessed lol)
Could anyone help me with this please? It's the one thing holding me back.

These are the generic filters and set value events I used to restrict the vertical movement:
Greater than 20.00 > on true > Set to 20.00
Less than -20.00 > on true > Set to -20.00
(and there's an "On False" going from the Greater Than to the Less Than)
