Audio

Each dialogue node contains a Dialogue Sound variable that you can attach your sounds to.

Dialogue Sound Attenuation

You can set a sound attenuation asset on your dialogue's class defaults to make the 3D, 2D or any other effect you wish to have.

Narrative will display an icon when a node is missing audio. This is a helpful hint to tell the user when they have missed it.

This can be disabled by going to Edit -> Project Settings -> Narrative Dialogues - Editor and unchecking Warn Missing Sound Cues
