It’s been a while since I asked this (last time I asked this it was 4.16), but does UE 4.19 natively support audio spatialization (and reverb/reflections) on Android for Samsung Gear VR / Oculus Go ? (not through Steam Audio, but without any plugins)
Along with the New Unreal Audio Engine, we have worked with Google to release Google’s Resonance Audio which is a spatialization plugin created for mobile VR solutions.
