RAJAMANGALA NATIONAL STADIUM — EDITABLE RECONSTRUCTION
Created 2026-09-13 in Blender4.3.2. Metric, 1unit=1metre. Stadium center at origin; X across pitch, +Y toward stadium north. Geographic north is about10.8 degrees clockwise from model +Y; no georeferencing claimed.

PURPOSE: Photo- and map-informed architectural visualization of the permanent stadium. No survey/CAD drawings were obtained. This is not an engineering, construction, fire-egress or capacity-certified model.

ANCHORS: Football markings105x68m; standard eight-lane track1.22m lanes with radius36.50m and84.39m straights. Mapped outlines constrain broad footprint and west canopy extent. Photographs constrain stepped high sides/low ends, roof sweep, facade rhythm and colors.

INFERRED: seat row counts/spacing and exact lettering distribution; tier risers/treads; exterior bay module and arch springing; concourse, stair, tunnel and press-room dimensions; pylon positions/heights; scoreboard screens/casings; nonvisible structure and context heights. Building/road footprints use OSM. Vegetation is an approximate distribution, not a tree survey. The exterior base and bowl are procedural approximations to the mapped outlines. No invented second roof: only west stand is covered.

CONFIGURATION: The supplied red/rust-track, red/yellow/blue seat references define the appearance. 2025 photographs were checked for permanent massing. No claim that every2026 maintenance change is captured; no temporary event covers/stages are modeled.

EDITING: 04/05 contain separate sector terrace meshes. 06 contains point meshes with Geometry Nodes seats: edit vertices to move seats and seat_rotation attributes to rotate. Shared seat prototypes under99_GUIDES. Modifier graph remains live in the master. 07 structural modules;08 circulation;09 west roof panels and framing;10 equipment;01 OSM-derived immediate context. Reference notes are under00_REFERENCE. Supplied image paths were absent on disk; their images were viewed in the conversation but could not be packed. 99_GUIDES includes1.75m scale object and mapped outlines.

MATERIALS: Shared Principled BSDF materials, procedural subtle concrete/grass variation. No external texture dependency. Meshes have planar tiled UV coordinates. GLB uses compatible base PBR factors; procedural noise is not baked into export, so exported concrete/grass is flatter than Cycles master.

LIGHTING: DAY and NIGHT are nested under12_LIGHTING. Toggle collection hide_render/hide_viewport and switch world between WORLD_Bangkok_Daylight and WORLD_Bangkok_Night. Day is default. A helper text SET_LIGHTING_MODE is included; set MODE then Run Script.

CAMERAS: Ten named inspection cameras including aerial, orthographic top, west/east interior, behind goal, field level, exterior entrance and wide drone.

EXPORTS: Portable GLB/FBX are generated separately after realizing seat instances on export copies. The master retains procedural seats and separate architecture. Collections map to export hierarchy where supported. Reference images, hidden guides and source prototypes are excluded from exchange files. Units are metres; glTF is Y-up, FBX uses standard -Z forward/Y up.

See SOURCES_RAJAMANGALA and external validation report for source record, checks and limitations.

VALIDATION: Cycles views inspected from aerial, top, east/west interiors, behind goal, field and exterior. Degenerate infield construction replaced with closed polygon slabs; apron overlap corrected; upper aisle risers divided to0.16–0.187m; roof upper ribs added. Major source solids have no non-manifold edges or zero-area faces.41 intentionally open roof skins have Solidify modifiers. See VALIDATION.md for export reimport results.

COMPLEXITY: 50,187 live seat instances, approximately2,445 master objects and282k source mesh faces. Portable exports realize instances to approximately4.24million triangles. Context is simplified architectural massing.
