no, what specifically do you mean by inverting the mouse?
So, the default behaviour is currently that if I move the mouse forward, the player looks up, and when you pull the mouse down, the player looks down, but what I'm looking for is an option to invert that, so pushing the mouse forward looks down and pulling the mouse back looks up instead.
Sort of like how people's heads pivot in real life. You push your head forward to look down, and pull your head back to look up.
