Hiya!
So I have a footstep sound effect that successfully plays it's default random container (dirt). I've added some box colliders in Unity to trigger the switch, and the switch message is showing up in the profiler in Wwise, however it just keeps playing the 'dirt' random container. I saw a post from 2016 where someone was having a similar issue and it looked like the answer involved properly targeting game objects, but unfortunately didn't come up with explicit instructions about what is wrong and how to fix it.
Side note: The effect also does a weird distant reverb thing every once in a while and I have no clue why. It started after I added spatialization and attenuation in Wwise, but they should be coming from about 2 meters below the listener (on the camera) so I'm not sure what's going on.
