Real-Time AI Conversations & Facial Animation for MetaHumans | Convai Unreal Engine Tutorial
In this tutorial, we show how to integrate Convai with Metahuman avatars in Unreal Engine, enabling natural, real-time conversations with accurate lip sync and facial animation. Using Convai’s updated @UnrealEngine plugin, your Metahuman can listen, understand, and respond naturally through voice, while Convai’s in-house neural animation system, NeuroSync, processes the live audio stream in real time. This drives highly accurate lip movements and facial expressions using MetaHuman’s 250+ blend shapes, resulting in expressive, low-latency conversational AI characters. This video focuses specifically on AI-powered Metahumans in Unreal Engine: from connecting a Convai character brain to a Metahuman, to configuring speech input, facial animation and more. By the end, you’ll have a Metahuman that can hold natural spoken conversations with believable facial animation, suitable for NPCs, virtual humans, training simulations, XR experiences, and interactive storytelling.
