Meta Unveils Realtime Avatar SDK for Horizon Worlds and Quest 4

Gaming · 4 min read

Meta's new Avatar Sync SDK captures minimal facial and body telemetry from Quest devices and compatible AR glasses and maps it to highly detailed avatars in Horizon Worlds and third-party apps.

The SDK focuses on bandwidth-efficient animation, using landmark extraction and procedural lip-sync to keep bandwidth and compute low. It includes privacy-preserving defaults so raw face data stays local unless users opt in to share expressive streams.

For creators, Meta provided ready-made expression modules and a plug-in pipeline that converts motion-captured sequences into reusable behaviors. The SDK aims to lower the barrier for more lifelike social VR experiences while maintaining user control over data.
