# High-Level Overview

At a high level, Existent extends Unreal Engine using its plugin system to add a suite of tools and library code. Additionally, the plugin directory contains some example and default assets for you to make use of or reference in your own projects.

Existent’s tracking layer allows you to seamlessly integrate a growing number of motion capture systems (outside in and inside out), hand tracking and IoT devices without altering application code. One of the most useful features in Existent is its ability to abstract away hardware. Where possible work with hardware via Existent rather than installing platform specific libraries. Existent exposes some functionality via C++ but we recommend using the provided Blueprint events and nodes where possible.
