Stylized Haunted Farmhouse - Modular Horror House (URP)

Build haunted farmhouses, abandoned homesteads and rural horror levels from one consistent stylized kit for the Universal Render Pipeline. The house is built from 2 m wall, floor, ceiling, porch and fence modules on a metric grid, with a 3.3 m storey and a 45° roof. Every piece is a ready prefab with colliders and lightmap UVs. The meshes are game-ready: clean quad topology, props with their own packed UVs and PBR texture sets, and seamless tiling materials on the architecture.

138 prefabs in 13 categories
Exterior walls & trim (12): clapboard walls with window, door, stairwell and damaged variants, outside corner, corner boards, downspouts (intact and broken).

Two scenes
Farmhouse: a furnished two-storey farmhouse with porch and yard under a moonlit night sky: hall and stairs, parlor with a burning fireplace, kitchen, bedroom, nursery and bath. Baked indirect light, light probes, a box-projected reflection probe per room, SSAO, volumetric night mist, firelight, oil lamps and candles. Press Play to walk the whole homestead with the included first-person controller and flashlight: from the picket gate through every room and up the hall stair to the upper floor; the doors swing open as you come near.
Overview: every prefab laid out by category with name labels on a 1 m grid.

Materials
76 props (furniture, kitchenware, lamps, doors, windows and shutters, the stair posts, the yard landmarks, trees, pumpkins and headstones) use standard URP/Lit materials with their own texture set: Base Color, Normal, Metallic-Smoothness and Occlusion at 512 to 2048 px, baked with edge wear, grime and streaks. They work in any URP project and can be edited in a paint tool.
The walls, roof, porch, floors, ceilings, foundation and the yard ground use 32 materials on the SG_FarmhouseMaster Shader Graph with tint, tiling, paint chipping, edge highlight, height-based grime, damp streaks, large colour variation, dust on up-facing surfaces, a random texture offset per object and a roughness override. The yard ground cross-fades to a larger tiling with distance, so it shows no repeating grid out to the horizon.

Volumetric fog for URP, as source
A renderer feature and volume override that ray march the main light and shadowed spot and point lights through their shadow maps, and can also fog reflection probe captures. Works in Unity 2022.3 and in Unity 6, with Render Graph on or in compatibility mode.

Game-ready
Colliders: render-mesh colliders on 95 prefabs (architecture, porch, stair, fence, trees and concave furniture), so doorways, stair treads and broken boards collide exactly; convex hulls on 41 props; none on the dead grass and the torn curtain.
Lightmap UVs in every mesh; architecture and the sheeted furniture are lightmapped, props use light probes.
Topology: props are 96% quads (4,599 triangles in 76 props, most of them around the punched and slotted parts of the pie safe and the cookstove); modular and structural pieces are 81% quads, 97% of their triangles where three single-segment chamfers meet; no n-gons; round parts with as few sides as their size needs. About 286,000 triangles for one copy of every mesh.
UVs: every prop has one non-overlapping 0-1 layout with even texel density (median fill 79%); modular pieces have UVs in metres, continuous across joints.
Bottom-centre pivots, rotation 0, scale 1; 1 unit = 1 m; texture UVs in metres.
Requires the Linear colour space; the Tools menu switches the project after asking.
