I am using Unreal 4.20.3 along with proper version of FMOD plugin on Windows 10. I tried to implement occlusion (as described in here https://www.fmod.com/resources/documentation-api?page=content/generated/engine_ue4/occlusion.html#/) in my project to no avail. Collision simply does not change parameter in FMOD event. I did set up in Fmod Studio event’s user properiets “Occlusion” “1” and added proper filter on master track. Also, I had tried adding parameter Occlusuion and used it to automate low pass of filter. In this case audio from the event had been muffled all the time, it hadn’t matter if collision happend.
Same method worked perfectly when working with UE 4.18.
My question is: is it an error connected with UE 4.20 integration, or maybe there is a chance that I am doing something wrong?
