Just curious, do you fly around in scene view or game view? I think I saw several videos where users were flying around in game view with play activated iirc. But mine seems locked somehow?
Both, but the camera only gets wacky in game view. Its a unity thing and has something to do with the camera type and creating perspective.
I am not sure why your play button would be locked? I notice you have different lighting... did you add anything to the camera?
