Greetings Sunshine_Arts_Studios! We see that this is your first time posting in the forums! We’re so stoked to have you join the Unreal Engine Community!
I am sorry to see that you are having issues with being unable to rotate the camera. Until someone else more experienced than me can assist you, would you consider trying the following:
In the Set View Yaw Min and Max (minimum and maximum angle at which the camera turns on the Z-axis) what are your values? Perhaps if you set the values right under 360 (-359.9 for min and 359.9 for max), you might be able to rotate the camera again. Let me know if this helps!
Also, are you attempting to rotate the camera independently or from a first person perspective?
(Note: I’m no expert by any means, just a neophyte trying to assist. )
