Playable Demo

Backrooms Megapack brings three connected Backrooms areas together in a single project: the mono-yellow wallpapered offices of Level 0, a concrete road tunnel Hub lined with red warning panels and slow extractor fans, and the brick and pipework service corridors of Level 1. Buzzing fluorescent light, repeating rooms and long dead ends, built for atmosphere first, an unsettling familiarity rather than jump scares.

Key Features

• Three connected areas in one level, each with its own palette : mustard wallpaper and dark baseboards, poured concrete and asphalt, exposed brick and pale pipework

• 860 unique display meshes, 150,031 triangles, 1 master material and 143 material instances

• 327 movable lights, every one casting shadows, Lumen and ray tracing enabled

• 14 looping fan animations, driven by level sequences, no rig required

• Custom collision : 347 hidden proxy meshes drive gameplay blocking, and every shipped mesh carries a simple collision primitive

• Nanite enabled on all 860 meshes

• Complete Unreal Engine project, open it and play immediately, no import step.

Included formats

Unreal Engine 5.8 project (Complete project), Blender source file (.blend), and GLB.

Requirements

Unreal Engine 5.8 and a DirectX 12 GPU with Shader Model 6. The project enables the engine plugins Interchange, InterchangeAssets and Enhanced Input. All three ship with the engine, no installation required.

Important notes

No custom characters, creatures or gameplay logic. Epic's ThirdPerson demo character, input and blueprints ship under Content/TheHub_level1_level2/Demo so the project is playable out of the box. Doors are static geometry. Interactive door behaviour needs the separate Nythrox Interactive Door plugin. No LODs in this release, Nanite is used instead. The three areas are connected inside a single level, not three separate maps.

Distribution mode

Complete project. The playable character and the Lumen and ray tracing settings live in Config/ and /Content/TheHub_level1_level2/Demo/, which the Asset package mode strips out.

Quality and Setup

Game-ready environment with organized files under a single /Game/TheHub_level1_level2/ root, custom collision proxy meshes on the playable geometry, and Unreal Engine 5.8 import verified.

Ideal for

Liminal space and analog horror games, backrooms style exploration, walking sims, found footage or short film sets, or as a modular base for your own underground level.
