Tools for characters that move and talk: webcam motion capture, AI-assisted posing, and NPCs that hold a conversation.
Best for NPCs that talk back with voice, memory and perception
A hosted character platform with an Unreal plugin, so you attach conversation to existing NPCs instead of building an LLM pipeline. Every generated line costs money per player, and Steam requires you to describe your guardrails for live AI content.
Best for Full-body and face mocap from a single webcam
New in Unreal 5.8: capture face, body or both from one camera, with no suit or markers. The same release lets Mesh to MetaHuman conform whole bodies, not just heads. The capture plugin is Windows-only and comes from Fab.
Best for Physics-correct keyframe animation with AI autoposing
AI posing and physics tools for hand-keyed animation. The free version is non-commercial and exports only its own format, so you need Indie to get FBX into Unreal. Yearly plans convert to a perpetual license.
