Procedural Backrooms Generation System

I built a procedural environment system that generates large, explorable “Backrooms” style layouts at runtime. It combines random room placement with corridor walkers to create a mix of tight hallways, intersections, and open areas while avoiding large inaccessible spaces. The system includes post-processing to break up long walls, connect nearby areas, and improve overall flow. It also features adaptive light placement based on spatial openness and a line of sight LOD system to keep performance stable in dense scenes.
