Backrooms Builder.

Build a Backrooms level, place lights, and record a first-person walkthrough—without learning Blender's complicated building controls.

A faster way to build

Make the level—not the setup.

Pick a wall, floor, or ceiling and click to place it. Everything snaps together, so you can make a clean maze in minutes instead of learning Blender's menus, coordinates, and modeling tools.

See it in action

Build. Light. Record.

The focused editor keeps level design simple: place structural pieces, choose ceiling fixtures from above, and record a first-person camera path without switching to Blender.

Why it is faster

Blender power without Blender building.

Blender is great for final rendering, but ordinary level building means learning modes, transforms, snapping, materials, camera animation, and dozens of controls. Backrooms Builder gives you only the tools this job needs.

Why it is easier

Everything already understands the grid.

Pieces line up automatically, ceilings stay divided for light placement, and your recorded walk becomes camera motion. You spend your time designing the maze instead of fixing misplaced geometry.
