HorizonForge reimagines collaborative VR world-building by seamlessly blending Meta Horizon's creation tools with real-time AI assistance. We set out to solve a critical pain point: the friction of switching between building, scripting, and asset generation. HorizonForge is our answer—unified, collaborative, AI-powered.
What it does: HorizonForge empowers multiple creators to co-build immersive environments in real time. Using AI pipelines (GPT-4 for procedural world-building logic and Stable Diffusion for visual assets), builders instantly generate terrain, textures, and objects, then edit and sync them live across devices. WebRTC and Firebase ensure ultra-low-latency collaboration so every change appears instantly for all users.
How we built it: Core platform (Unity 2023.2 LTS, Meta Horizon Worlds SDK, Meta XR SDK), AI & Intelligence (OpenAI GPT-4, Stable Diffusion API), Backend & Sync (Node.js/Express, Firebase Realtime Database, WebRTC). We developed the interface in Unity, wired it to our Node.js backend, and orchestrated sync across Firebase.
Challenges: Getting WebRTC stable in multiplayer VR, synchronizing AI-generated assets without breaking state, performance tuning on Meta Quest, timeboxing AI calls to maintain low latency.
Accomplishments: Built a fully functional multi-user collaborative VR builder, integrated two AI pipelines directly into workflow, achieved reliable cross-user synchronization, delivered a smooth-running Meta Quest demo.
What's next: AI-driven NPC scripting, a marketplace for sharing/remixing worlds, asset streaming optimization, and open-sourcing components for the Horizon creator community.
