Try to use audio gameplay volume instead of audio volumes, its a plugin thats needs to be activated. It’s go to audio volumes these day. You should be able to add them into BP haven’t try that myself, we are using level instances for buildings
Sorry for late reply lol.
The best way to do this is to use UE5 packed level instances.
If you’ve used prefabs in Unity they are pretty much the same. You can store pretty much anything in them. Environment assets, Audio Volumes, Ambient Sounds, and blueprints. Then you just drag them into your main level.
I recommend enabling the Audio Gameplay Plugin and using Audio Gameplay volumes, they are much more modular than the old audio zones.
If you want to trigger sounds on entering the audio gameplay volume you can make a blueprint which sits in the level instance and has a reference to the audio gameplay volume.
Then drag off from the reference and search for assign on being overlap, then use the event that is created to play your sounds.
Just make sure your audio gameplay volumes brush components collision is set to generate overlap events and you have the collision preset set to overlap everything. I also disable “can player step up on” as an extra precaution.
Hope that helps!
