Hi guys,

Sorry I am a complete noob at UE4 but I am an experienced sound designer. I have used FMOD and UE4 to some extent before but I cant seem to get the ambient volume to duck when I walk into my box trigger.

Basically I need the outside ambient volume to Duck when the player character walks into a building. Can anyone help, I’m sure it’s not difficult but I can’t seemed to find a quick fix tutorial or any other information to help me.

Thanks

I’m not sure if this will fully work:

Create an Ambient Sound for the building.
Assign the outside and the inside ambient sounds to separate SoundClasses.
Add a Passive Sound Mix Modifier to the inside SoundClass.
Set the SoundMix so it drops the volume of the outside SoundClass.

That way, when you are inside the building, you are triggering a SoundClass, which triggers the SoundMix.
