Existent Unreal Engine Plugin

  • Created By: Existent
  • Date: 2024
  • Client: Existent
  • Technologies: Unreal Engine, C++, Visual Studio, Postman, Gitbook, Keygen

Project Overview

The Existent® Unreal Plugin is a comprehensive software framework designed to simplify the development of multiplayer, location-based virtual reality (LBE VR) experiences with natural, physical interactions. It provides a robust end-to-end suite of components, Blueprint nodes, assets, editor tools, and runtime systems that help teams design, develop, test, and deploy immersive VR experiences.

Key Contributions

Licensing System Development
I designed and implemented the plugin’s licensing system in C++ that leverages HTTP requests to interact with the Keygen RESTful API for:

  • License key validation
  • Machine activation
  • Entitlement verification

Demo Experience – Realm Odyssey
I created Realm Odyssey, a mini-demo experience built in Unreal Engine to demonstrate core features:

  • Dynamic level streaming for seamless world transitions.
  • Tracked object and vehicle mechanics to maximize immersion and player engagement.
  • Intuitive interaction flows designed for first-time users.

Highlights

  • Integrated licensing flows with real-time activation and entitlement checks.
  • Developed immersive VR mechanics blending dynamic level loading and tracked hardware.
  • Created developer-friendly workflows supporting in-headset debugging and session playback.
  • Contributed to a flexible architecture enabling free-roam multiplayer VR.
