NEW ROOF: Katsukagi /3DTextures.me, CC0 https://3dtextures.me/about/ https://3dtextures.me/2018/09/25/asphalt-shingles-001/ Public source folder: https://drive.google.com/drive/folders/1jZCaEVlgDtFcjY3hRnCtH46Os85_PT9Z Downloaded five1024x1024 maps: color,roughness,normal,height,AO; original source sizes and direct public download URLs recorded in roof_source_assets_v12.json beside this file. Original generated-shingle / asphalt-granule composite is REPLACED, not merely relabeled. Basecolor palette-matched to existing brown roof; roughness calibrated0.65+0.30*map, normal strength0.45.16courses per tile,5.5in exposure;13in tabs/39in three-tab grouping. Eave-parallel UVs use actual sloped distance, applied to18roof planes.7folded ridge caps. This is a downloadable regular asphalt-shingle PBR set, NOT a manufacturer-specific laminated architectural-shingle scan. Free source is1K; upsampling would not add detail. Standard basecolor/roughness/normal exported. Height/AO sources packed in Blender but not applied as silhouette displacement: original roof planes/pitches remain unchanged. Vegetation: authored procedural oak/hickory-like trees and low beds,224883 volumetric 3Dgrass placements with twelve curved folded blades near/six middle/three far, GPU instancing and distance/frustum LOD. Same placements asV10. Generic Missouri-inspired rolling terrain/planting are visualization assumptions, not a surveyed Festus site. Existing driveway/apron retained; road approach unsurveyed. No AI-generated render substitutes. PORCH CORRECTION supersedes V11's WRONG clipped-base interpretation: Original vector sheets4-5 (first floor),3-5 (foundation),1-5 (front elevation). Foundation explicitly21ft8in wide=11ft8in+10ft; depths8ft10in/6ft10in with2ft step. First-floor20ft/8ft/6ft strings reference beam/stud faces, not slab edges/post centres.

Door/aperture moved18in south, old hole patched. Rear wall-adjacent dining railing removed; open-edge guards/stair rails retained. Boolean wall fins outside actual rearY74 and garage-westX56.3333 planes repaired in MESH, not painted out. Rear doors have recessed tracks and slim2.5in/5/8in exterior trim. Door wall headers exist17main+12basement; viewer now shows them in eye-level views. Orthographic elevations hide tree/canopy meshes, keep grass and HDR illumination. Parallel ortho rays cannot naturally project a wide sky: elevation background uses a 2Dsky crop of the SAME HDR image, not finite sky-sphere geometry (which can leave bands). Blender proof uses a camera-only HDR emission backdrop; world lighting unchanged. Ground has closed below-grade volume; exact terrain top/foundation opening is unchanged. Elevation framing puts grade at bottom of viewport, not the underground terrain side.
