    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

The plugin is intended to retarget real-time human body motion to any skeleton by using SteamVR-compatible VR Headset (HTC Vive), Motion Controllers and tracked devices (Vive Trackers). It's also possible to use Scene Components instead to provide input from third-party tracking systems. The plugin supports custom skeletal meshes and can be used both for animation 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. Main demo project is ready to capture animation at UE4 Mannequin skeleton and to save resulted animations in Anim Sequences for future export in FBX format.

Minimum setup (for in-game VR avatars)

Two trackers for feet, one tracker for pelvis, two controllers (or trackers) for hands, HMD (or tracker) for head

Recommended setup (for animation capture)

Two trackers for feet, two trackers for spine (pelvis and ribcage), two trackers for elbows, two controllers (or trackers) for hands, HMD (or tracker) for head

Maximum setup

Recommended + two knees trackers

I provide long-term support and consider personal requests.
