# Unreal SDK — Markerless Mocap for Unreal Engine

The AR 51 Unreal SDK connects an Unreal Engine project to AR 51 real-time markerless motion capture — receiving live skeletons to drive characters, with LiveLink streaming, VR platform support via OpenXR (HTC Vive and Meta Quest) plus PICO, and Blueprint and C++ integration. This page covers installing and configuring the plugin; the rest of this section covers projects, character assignment, LiveLink, and the VR platforms.

After completing this guide, your Unreal Engine project will be connected to a running AR 51 service and ready to drive characters from live motion capture.
