Steam audio: Attenuation plugin setting doesn't available (UE4.20)

Hello,
I have followed all the steps in order to setup STEAM AUDIO and use for audio occulsion.

  1. First, i have created a shortcut (with the extension -audiomixer) and run the project.
  2. Edit/plugin/audio STEAM enabled
  3. In Project setting/plattform/windows : steam enabled as plugin preference
  4. I created an audio asset
  5. I added an attenuation distance asset

But, even i override or not override atteniuation setting,
i don’t find the section attenuation plugin seeting.

So i follow all the steps after :

  1. For the sound source asset: i add a component phonon source (unic identifier: 1)
  2. For a wall: i use a basic cube mesh: add component: phonon material and phonon geometry
  3. I add a phonon probe volume, and i generate probes (i obtain a grid of blue plots)
  4. I back the source, all is clean,
  5. I run, and nothing happen, just UE4 basic sound attenuation without occlusion

I think that the problem comes from audiomixer?
Thanks for your help, it will be very precious…

C’est bon, problème résolu.

you havactivate the audiomixer with this steps:

  1. create a desktop shortcut of the engine
  2. right mouse click - choose properties
  3. in the shortcut tab/Start in add: -audiomixer
  4. press apply, ok
  5. Done:)

It should look like that
“E:\Engines\Epic Games\Versions\UE_4.20\Engine\Binaries\Win64\UE4Editor.exe” -audiomixer

Cheers!
