The workflow
HauntBuilder covers the whole design loop — sketch the floor plan, walk it under haunt lighting, check it against fire-code basics, then hand off plans and material lists.
Drag walls, doors, actor runs and FX nodes onto a snapping grid in the 2D editor. Modular wall panels — 4 ft and 8 ft solid, plus curtain, chain-link and plexiglass — snap to 1×1, 4×4 or 4×8 ft grids, so layouts stay buildable and measurable.
Switch to the 3D walkthrough and move through the haunt in first person at eye height. The lighting simulation matches the dark experience: dimmer nodes become dimmable point lights, strobes flash, fog nodes drive scene fog, and a camera flashlight helps you test what guests will really see.
The safety validator flags corridor widths under 3.5 ft (measured wall-to-wall) and dead-end or sealed rooms with no egress route, so problems surface before construction. The guest throughput calculator estimates capacity per hour from path length, bottlenecks and group batching.
Hand off print-ready plans and material lists. Vector PDFs come in two presets — Building Inspector (with fire-code corridor annotations) and Actor Training (scare and FX symbols) — and the BOM auto-counts flats, fasteners, doors and zone-grouped electrical drops.
