Using SteamVR tools for real-time motion capture

  • Supported Platforms
  • Supported Engine Versions


The plugin is intended to retarget real-time human body motion to UE’s skeletal mesh by using SteamVR-compatible VR Headset (HTC Vive), Motion Controllers and tracked devices (Vive Trackers). It supports custom skeletal meshes and can be used both for motion capture recording and for in-game player body representation. Transforms of untracked bones are reconstructed by using inverse kinematics.

The plugin supports tracking of feet, knees, flexible spine, shoulders, elbows and hand palms. Demo project includes a level ready to perform motion capture and save result animations in Anim Sequence for future export in FBX. Duration of Anim Sequence assets is limited to 60 seconds.


1) SteamVR-compatible VR headset, two Motion Controllers, at least 1 Vive Tracker

or: 2) SteamVR tracking system (two Base Stations and Link Box) and at least 4 Vive Trackers.
