I’ve been trying to get acoustic ray tracing up and running in 5.5 using Meta’s XRAudioSDK 77.0 but I’m not having any luck. I’ve followed all of the documentation but I’m not hearing any audible changes when I apply different acoustic materials to the meshes included in the baked acoustic geometry.
I’ve tried applying acoustic materials to child meshes, and to meshes which each have an acoustic geometry component. I’m baking the acoustic map after each change to no effect.
Has anyone had a similar issue? Everything runs fine when I implement the XRAudioSDK in Unity projects - so there might be a UE specific thing I’m missing?
