I'm creating a obstruction/occlusion system in UE4.20 with Wwise and most things are working now. But I want it to not trigger all the functions if the sound source is further away then the Sound Events attenuation radius. But whatever I try, the "Get Attenuation Radius" object returns 0 in value. I've debugged it in both UE4 and Wwise and checked that is the same AK Component that triggers the sound and sends information to the "Get Attenuation Radius" object, and I think I've set all 3D settings correct.
Wwise attenuation settings:
I think I found the answer, I had to check these metadata options in the Soundbanks tab in the Wwise project's Project Settings.
