Each feature connects to Convai for a specific purpose — executing in-scene behaviors, expressing emotions, remembering players across sessions, following authored narrative graphs, or perceiving the world through a camera. Every section includes a conceptual overview, a quick start, Blueprint property references, usage examples, and troubleshooting guidance. Select a feature to get started:


Character actions Let Convai return structured action sequences your Blueprint event handlers execute — move to objects, follow the player, or run any custom behavior.	/pages/NjVHOB3MELicvSSurEPd
Dynamic context Push live runtime state — health, inventory, zone, events — into the character's context window mid-session without restarting the connection.	/pages/VtreGBSkV3v9EqIKSNQH
Emotion Translate Convai emotion signals into per-emotion blendshape weights and scores on any skeletal character.	/pages/dXQYIyvmX3Z6hN65zfqt
Long-term memory Give characters cross-session recall via Speaker IDs and session continuity — characters remember individual players, facts, and past interactions over time.	/pages/DMTej4CYSOHRGmpxRVHi
Narrative design Structure character behavior around an authored story graph — sections define objectives and tone, triggers advance the narrative, template keys inject live gameplay data.	/pages/adQWw1CiOcNdZRsmpBeB
Scene metadata Tag world actors with `UConvaiObjectComponent` so Convai characters know which objects exist in the scene and can reference them by name in conversation.	/pages/vbGxc89Y9wflNJFl3EW4
Vision Stream scene frames from a capture component to Convai so characters can perceive and discuss what the player sees in real time.	/pages/5TGq7ASz4xWw1Dhn8qy3
Gaze attention Use player line-of-sight to direct which scene object a character focuses on — sustained gaze promotes objects to active attention with configurable dwell timers.	/pages/LWOprxC8MMYzTxzOV4pu
Lip sync Drive mouth and face blendshapes in sync with Convai speech using `UConvaiFaceSyncComponent` — supports MetaHuman, ARKit, CC4, and viseme targets.	/pages/MUqoUJUdEwZL84AyCxoU
