Yes, that sphere is what I tried. I am not sure what’s the difference between 3D panner and 3D Object panner.
I deployed to Android/Gear VR using 3D Object panner instead of Oculus Spatializer in FMOD Studio: https://s12.postimg.org/7f69psfiz/fmod_studio_3_DObject_Panner.png
With that I can clearly hear direction from which sound is coming from, but attenuation doesn’t seem to be working - I crossed the level and could clearly hear the sound from another end of the level. Maybe it’s just settings on the spatializer, not sure. Didn’t have all these issues with UE 4.12
