Hi, I have a bizarre problem and can't figure out why 3D panning would ever work like this. I checked everything that I could think of that could have been broken, and have run out of ideas.
What happens, is as you pass a 3D object, the panning volumes jump quickly from (-infinity, 0) to (0, -infinity). 
It's a 2D game, so first thought was that the listener was at the same z level and so the angle measured between the listener's orientation and the object was causing it, but after checking the game object profiler it seemed like everything was in the right place.
I made sure the listener orientation was hard-coded pointing forwards towards the objects. I also made sure the pan rule was set to "Headphones" by default.
Also, attenuation works fine and the listener moves with the camera, so I can only assume Wwise has everything it should need to calculate panning volumes for each object, but it's not. I am very confused and would appreciate any ideas as to where else 3D positioning might be broken.
