Breakdown of our Unity Modules

As of Unity Modules 4.5.0 — The Interaction Engine and Hands Modules are included in the Unity Core Assets package.


The Core package provides the foundation for VR applications with a minimal interface between Unity and our hand tracking controllers.


Interaction Engine

A customizable layer that exists between the Unity game engine and real-world hand physics. Use the Interaction Engine to create natural object interactions and user interfaces. Supports both hands and PC controllers. An example demo build is available on the Gallery.


Hands Module

Our Hands Module is a set of scripts to help you bind leap motion data to your own hand assets. You can now import your own customized hand models and have them work with our world-leading hand tracking.

Don’t have your own hand models? We have a range of optimized and rigged hand models you can choose from. You can also quickly switch between a modelling package and seeing the models driven by live hand motion in Unity.



Current and past versions of our Unity Modules can be found in Releases. For older assets (including OSX-compatible packages), see our documentation page.
