This backend displays nodes for all conversations and quests that are referenced by the active scene, as well as for those scene objects. A connection is created for each such reference.
Load the scene you want to analyse. Click the Show active scene button in the toolbar to generate the graph. Through a conversation’s node context menu you can open the conversation in the dialogue editor.
The backend will ship with RelationsInspector soon.
