Warehouse construction piece inventory

This is the construction kit’s source partition, not its palette asset list. The builder maps source instances to reusable prefabs through catalogAsset in pieces.json; source IDs below are not necessarily loadable catalog IDs. The shipped bundle:thps/Warehouse, its assets and levels/thps.mblevel.json remain unchanged. See asset-bundles.md for the piece prefabs, their pivots and the pieces.json sidecar, and the reference, shipped layout and preservation check.

Source and addressing

Source: .tools/thps1/warehouse/warehouse.obj, from the PS1 extraction. Source SHA-256: 917aa268b447df4e7131cac0b55cbf0894e848789c86289daf845d25a562b25a

There are 252 object declarations, 200 nonempty objects and 1,345 polygon faces, assigned to 214 named source pieces below. A face number is the one-based ordinal of an f line across the whole file, before triangulation, coplanar separation or importer filtering. Ranges are inclusive; comma-separated ranges form one piece. Groups are the literal o hashes, not material hashes. Every source face has exactly one owner, including double-sided faces and suppressed post remnants. There is no catch-all remainder. A source row may yield multiple independently editable instances when it contains disconnected sign copies; sourceId records their common inventory owner. Module types describe reuse, not a second face assignment.

Empty objects: 947969A2, 0D703818, 7A77088E, E4139D2D, 9314ADBB, 0A1DFC01, 7D1ACC97, 0108955F, 9801C4E5, EF06F473, B31D819B, D0B9495C, 2A14D021, 49B018E6, BE5B0A8C, 27525B36, 50556BA0, CE31FE03, DFB35C91, 46BA0D2B, 6F12583B, 954EED36, F61B0981, 811C3917, 1F78ACB4, 687F9C22, 1E575FE1, 875E0E5B, 370A0C19, AE035DA3, 271B3BAD, D9046D35, BA664D03, CABEDA1B, 4760F896, 9F9D74DB, 86B0FA50, 0C47BC8C, EF5B1379, 817474C9, 27CBD007, 187D2573, F673445F, 6FD0D543, 0DE57681, F28254C7, A114B35C, 94EC273B, 7B408C1A, E52419B9, F0593ECD, 6E3DAB6E

Those 52 declarations have no geometry and need no palette placeholder. They are accounted for separately, not assigned invented faces.

Run uv run scripts/check_thps_piece_inventory.py to verify the fingerprint, empty declarations, selectors, unique names/IDs and exact face coverage. The same check runs in pytest and fails rather than skips without the extraction. The Markdown tables are the machine-readable inventory; edit them rather than maintaining a competing manifest.

Coordinates and preservation rules

Measurements here are Megabonk world units, not the reference video’s estimated metres or its map headings. Transform raw OBJ (x,y,z) to ((x-1.519043)*79.2+100, -y*79.2+0.5, (z-1.9661865)*79.2). World north is +Z. Keep unrounded source coordinates/UVs in meshes; numbers below are rounded for reading, never snapping targets.

Use one canonical pivot at the midpoint of a module’s lower riding edge, with local +Y up and +Z pointing from toe toward lip; deck/flat pivots are their walking-surface centres. Corner pivots are at the intersection of the extended lip lines at deck height. Wall/window pivots use bottom-centre of the panel. Reusable signs/props/kicker parts use canonical geometry frames; their full sidecar transforms, rather than a source location or yaw alone, define the placement. Roof sections retain the Warehouse axes and use their geometry centre. Store the inverse pivot transform so reassembly restores the original world vertices; standardized loose planks retain their fitted bounds/artwork rather than incidental source skew. These are kit conventions, not changes to the legacy mesh’s centre pivot.

The start area contains paired state/double-sided geometry that the importer currently draws together. Rows naming two groups retain both, including nonidentical material variants; do not deduplicate them on the assumption that only one should be visible. Preserve global CoplanarLayering offsets before partitioning so posters and planks do not gain different offsets when their neighbours move. Triangulation, winding, UVs and transparency stay as in ThpsPack.cs.

Source face inventory

Hanging glass box

The room occupies x 149.36–178.95, z 20.93–31.47. Its window objects are individual window sections, not every small pane painted in a texture. Each two-face window is the two sides of one section and moves as one piece. The east wall is part of the arena wall panel below, not an eighth glass window.

Floor top is 15.640, bottom 15.311; roof underside is 25.424, top 25.753. Keep each slab’s top, bottom and edge faces together. Intact room windows (F2184063) are collision-open only in the authored room bounds; broken windows (FA88F30D) are always collision-open. Their frames remain solid. Window pieces must carry that result locally, not keep testing the old world bounds after movement. No new breakable-window gameplay is implied.

Wall quarter pipes, corners and decks

Deck faces are split from riding transitions even when the original object mixed them. Lip/coping strips stay with their transition; grind paths follow their owning transition, not the adjacent deck. Names use measured world location rather than uncertain remake wall names.

Start platform, roll-ins and upper enclosure

The two roll-ins are separate left/right modules. Start flat-bottom geometry belongs to the platform, not the long roll-in. The high rear quarter pipe has the same 8.06 rise as a wall pipe but starts at y 27.78.

The two start windows are intact F2184063 sections but collision-open at their starting location. The two frames still block. The source has neither remake door splinters nor a separate animated roll-up-door asset to expose.

Arena floor, ledges, walls and structural supports

These are named spatial panels, not one uneditable shell. Wall panels include their textured brick/window bands; those painted bands are not separate glass objects. Deep skirts and subterranean details remain individually accounted for even though the kill floor makes them unreachable.

Rails, taxi, kickers and loose boards

The big rail’s straight and bent bars are separate pieces, including both visible sides. Suppressed post plates get an explicit owner/disposition: they are archival post-remnant pieces, excluded from the default assembly’s render and collision, matching RemoveRailLeftovers. Do not accidentally restore them, or omit their accounting because they are hidden in the legacy mesh. They can be exposed as optional repair/debris pieces, not structural posts.

Taxi bounds are x 121.64–137.36, y 0.83–5.24, z 76.17–81.57. Its eight surrounding sloping boards are separate pieces, not welded into the car. Kicker frames and boards may be grouped for placement but remain independently editable; north board/frame meet near z 44.44–47.60, south near z 61.13–64.28, board tops y 3.30.

Signs, posters and graffiti overlays

These IDs identify source instances for face accounting. The palette uses deduplicated artwork/geometry assets; pieces.json maps each instance to its catalogAsset and placement transform. Identical artwork need not have an entry for each wall where it appeared.

These are textured overlay faces, not new mesh lettering or remake props. Each row can move independently of its supporting wall. Paired start-area copies stay with the same sign. Materials identify appearance, while the source selector determines ownership.

Ramp module profiles and mating contract

Profiles are the original piecewise-linear riding surfaces, not circular quarter pipes fitted to a radius. Keep every profile vertex and texture seam. For the table below, (run,rise) starts at the toe; run points toward the lip. Width can vary independently only when both mating edges retain the same profile; uniform scaling is the safe initial palette transform. A reflected module needs reversed winding/normals, not merely a negative collider scale.

Module	Measured profile and height	Width and mating edges
main-transition	South profile (0,0), (4.931,1.334), (8.334,3.364), (10.538,6.671), (11.312,10.054), (11.370,10.692); toe y -4.933, lip 5.759	Six 19.722-wide strips across x 119.781–178.949. Like-side profiles butt together; north is a near mirror with small source differences, not an exact reflection. Toe joins flat at z 19.945 or 32.436; lip joins the outer bank at z 8.595 or 43.806 (no horizontal main-pipe deck).
flat	Main bottom y -4.933, depth 12.491 (z 19.945–32.436)	Rectangular bottom joins both main toes. Start flats are separate at y 27.783, not interchangeable at the same elevation.
hip-apron	Seven triangular sloping faces from x 100.058 at y 0.5 to the main west profile x 119.781 at y -4.933–0.5	Joins rectangular flat and the lower parts of both hip transitions. It is not a flat-bottom module despite occupying the bottom of the tapered end.
outer-bank / bank-end	Straight bank rises 5.259 over run 7.889, from floor 0.5 to lip 5.759	Three strips on each side share the main transition lip; opposite toe meets arena floor. Two triangular west end pieces mate the hip end. South east strip is not rectangular: it meets the 3.787-high ledge.
hip	West end tapers from lip y 5.759 at x 119.781 to floor y 0.5 at x 100.058; three original faces per side	East edge mates to full main profile; west edge closes onto floor. Diagonal lip ends at z 3.51/48.87, not the straight lip’s z. Keep both asymmetric end types.
wall-transition	Typical (0,0), (1.547,0.522), (4.466,1.972), (6.574,4.447), (7.425,7.077), (8.082,8.063); floor 0.5 to lip 8.563	Straight widths usually 19.722, with longer/shorter source runs retained. Side mates use the full profile, toes meet floor, lips meet deck. Upper north tier has same rise from 8.563 to 16.626; start rear from 27.783 to 35.846. Slight source variations (including steel faces and a 0.019 vertex offset) must not be rounded away.
corner	Same wall rise 8.063 swept through the three faceted sectors of a 90-degree concave turn	piece-pocket-return and piece-southeast-corner mate at both straight profile ends; their split decks fill the inside lip polygon. Rotate to reuse; do not replace with a smooth torus.
convex-tip	Same wall rise, each tip half turns 90 degrees in two faceted sectors; full tip turns back 180 degrees	West/east tip halves meet at x 80.335, lip z 85.030; side lips continue at x 77.048/83.622, z 88.317. Mate side transitions at z 88.317. Coping uses two chords across four mesh edges, not four short grind rails.
deck	Flat walking surface at the parent lip elevation; room slab thickness 0.329; wall decks generally 3.287 deep	Mate lip boundary without overlap; straight outer edge can mate another deck. Corner decks are polygonal, not bounding-box rectangles. Keep source fascia with its deck.
roll-in	Toe (z,y) is (-19.017,0.5), then (-20.564,1.022), (-23.483,2.472), (-32.262,8.447), (-40.499,16.007), (-48.756,22.562), (-58.017,26.952), (-65.752,27.783), (-73.312,27.783)	Two tapered entrance lanes, separated by the centre pillar/channel. Upper edge meets start flat y 27.783; lower edge meets floor y 0.5. Width changes toward the top: preserve the boundary polyline, not a rectangular substitute.
kicker	Board rises from about 0.38 to 3.30 over about 10.06; frame from 0.5 to 3.19	North/south boards face opposite directions and meet their frame at the original lip. Toe meets floor; side and rear edges are terminal, not quarter-pipe mates.
ledge	West/east top y 3.787, floor 0.5; vertical front with shaped plan outline	Top may mate a deck at y 3.787. This is an end/curb module, not a rideable transition. Separate skirt retains its own below-floor faces.
end-cap	East quarter pipe terminal face at z 79.770, y 3.710–8.563	Vertical terminal face joins the 3.787-high east ledge and upper transition/deck boundary. It is not a riding face or a substitute for a full-height wall.

The below-floor strip at faces 239–250 is an archival transition/end strip (y -7.54–0), not an alternative floor-height wall pipe. Preserve it in the assembly; never use its bounds as the regular wall pipe’s profile.

For joins, compare the ordered boundary vertices after placement, not just bounding boxes or nominal heights. Endpoints must coincide at source precision and adjacent riding normals follow the original faceting. The wall ends and hip ends above are the terminal modules; do not invent caps across open riding edges. Splitting additional width strips is permitted later only along existing face boundaries (or an explicitly recorded new cut with interpolated UVs).

Importer and generator additions

No source-face selector is possible for these: their source is the named code/config value below. Every enumerated instance needs an editable transform or setting, not a hidden consequence of the monolithic Warehouse placement. The separate editable assembly uses these geometry assets, snapshots local grind/support attachments and keeps the game placements and level settings below editable. Ownership does not prevent selecting an individual support or path; see piece attachments.

Inventory ID / instances	Authoritative source	Editable form and ownership
added-roof-section-ordinal	ThpsPack.AddRoof, WarehouseRoof.Quads, spill-level ceiling and edge wall profiles	Consolidate emitted faces into larger 40-by-40-world-unit footprint sections, preserving every ceiling step, skirt, underside and inset rather than substituting a flat lid. Shared canonical panel assets are referenced through pieces.json; each placed section has its own collision and selection. The room/source roof rows above are separate.
added-floor-patch-0	FloorPatches[0], AddFloorPatches	One floor patch, OBJ x 0.52–0.76, z 2.58–3.04, y -0.003 after Y flip; world x 20.876–39.884, z 48.614–85.046, y 0.2624. Keep fitted floor UVs and depth under decals.
added-post-0 through added-post-6	RailPosts[0:7], AddRailPosts	Seven independent 0.5-wide box posts below big rail: (x,z) (75,4), (75,16), (75,28), (75,40), (75,52), (78.3,56.8), (81.4,60.5). Bottom y 0.5, top 3.17, five faces each. Associate with straight/bend bars without baking into them.
added-post-7 through added-post-9	RailPosts[7:10]	Three deck rail posts at (175.66,49.1), (175.66,61.3), (175.66,73.45), bottom 0.5, top 8.31. Same independent selection and collision as big rail posts.
added-grind-mesh-0 through added-grind-mesh-3	MESH_RAILS, hidden_rail_edit	Four hidden game rail paths: big straight, big bend, sign rod, deck rail. Attach local path/collider metadata to the matching visible rail; expose path editing/selection even when render-hidden. Transform and delete with the bar; no second visible game rail.
added-grind-coping-0 through added-grind-coping-27	Every ordered COPING_LIPS entry via COPING_RAILS/rail_along	28 paths: indices 0–3 are main north/south and their west hips, 4–22 are the 19 wall/pocket lips, 23–26 the four west ledge lips, 27 the start lip. Keep exact source endpoints and two-chord pocket tip. A path spanning adjacent strips needs explicit ownership/subpaths without duplicate catch regions; splitting must preserve handoffs and avoid paths shorter than 3.5. Decks must not own a second copy.
added-boss-portal	boss_spawner(), level bossSpawner	Editable boss portal at (170,15.6,27), scale 0.4, yaw 90; retain hidden BottomPiece and Collider. Select/move the portal independently of the room.
added-boss-spawn	level bossRedirect	Boolean level setting that keeps the boss redirect on. The redirect picks its own walkable spot, so there is no destination marker; moving room/portal must not silently put the boss inside a closed room.
added-radio	radio_edits, RADIO_POSITION	Ordinary interactable/boombox at (90,35.9,-123.5), separately movable/deletable. Playback track belongs to level music setting, not its geometry.
added-pile-R1 through added-pile-R5	Baddy nodes 43,107,109,111,113; collectibles()	Five separate interactable/chest placements. These are replacements for goal piles, not five extra source crate meshes. Keep final anchored/overridden transforms.
added-letter-S, K, A, T, E	Letter nodes 28,29,17,13,12; LETTER_SHRINES	Five independently editable forest/shrines/0..4 objects. T is the merchant prefab. Preserve upright rotation and deliberate overrides, not just node coordinates.
added-tape	Node 16	Separate interactable/chestFree inside the room.
added-bonus-15, added-bonus-30, added-bonus-31	LANE_BONUS_NODES	Three separately editable free chests. Nodes 148–150 (100/200/500 cluster) are intentionally not placed: no invented kit instances.
added-player-start	PLAYER_START, level spawn	Editable start marker at (109,38,-116), where y is player centre, not feet. Marker saves the level setting independently of the portal.
retained-spawn-portal	PlayerSpawnPortal	The game still creates its own portal; it is not in the file, so it is not separately selectable. Do not conflate its transform with spawn.
retained-forest-particles	ForestParticles	Created by the game without a placement; not OBJ geometry and not in the file.
added-terrain-bootstrap	authored_grid, FLOOR_CELL	One authored tile (10,7), height -2, slope none, on the 15x15 stock grid. Expose normal tile edits; the game needs it to derive its catch floor.
added-clutter-removals	none	A from-scratch level generates no clutter, so there is nothing to remove.
settings-gameplay	killFloorY=-35, maxSlopeAngle=88, grindRequiresSlide=true, noGrass=true	Authored level controls, editable and saved once per level. Do not bake them into individual ramp assets.
settings-music	music=bundle:thps/04_Superman	Editable track reference, independent of boombox transform; soundtrack bytes stay baselined.
settings-presentation	title, description, mapDescription, allowedCharacters	Editable level metadata; initial values come from build_level() (Calcium/Tony McZoom restriction).
settings-generation	map=1, stageIndex=0, tier=0, packs	Editable kit and pack dependencies. baseline: none, so nothing is generated from a seed.
settings-format	schemaVersion, gameBuildId	Serialization/compatibility metadata, preserved by save/load rather than represented as scene objects.

Roof generation must run against the same pre-partition geometry and post repairs as the legacy importer. Re-running a spill calculation separately on each movable piece would change its output and is not equivalent. Store the baked roof panel transforms; do not rebuild it implicitly when a ramp moves.

Landmark cross-check

This checks the inventory against the structures and M1–M15 map labels in the reference. The reference mixes remake imagery with a PS1 extraction: an unmatched remake detail is not evidence for adding geometry to the preserved PS1 assembly.

Reference landmark / structure	Inventory coverage and limits
M1 winding bank, M10 south notch	South wall transitions, pocket side/tip/return modules and split decks. Their world-space positions, not uncertain map headings, define placement.
M2 west platform / ledges	West Shorty’s ledge, its skirt, adjacent floor, deck rail/sign rail where measured; five chest replacements remain separate. The remake/map’s rail names do not prove a different source ownership.
M3 taxi	piece-taxi plus eight surrounding loose boards; distinct from the wall ramps.
M4 half pipe	Six transition strips, rectangular flat bottom, sloping tapered apron, six outer bank strips and their two end pieces, and two hip ends; four authored main/diagonal coping paths.
M5 glass corridor / secret room	Three wall frames, arena east wall, five individual window sections, floor and roof slabs, underside support and suspension pieces; tape, boss portal and destination separate.
M6 north bank, M7 middle quarter pipe/pillar, M8 east channel	Three lower north runs, upper tier, two independent roll-ins, centre/rear lintel assembly, side panels and window frames. The reference’s exact map-to-world headings remain uncertain.
M9 east deck / back pipe	Tier platform, south/east deck/transition rows and the east ledge-height end cap cover the extracted decks and back pipes; do not substitute remake measurements for the source placement.
M11 south-east ledge	East low ledge with top/front faces, drain floor and adjacent arena wall.
M12 kickers	Two frames and two opposite riding boards, not one combined kicker pair.
M13 dark pit	Reference identification is unresolved. Extracted underfloor skirts, below-floor transition and drain panels are all assigned; no fabricated pit prop is needed to close coverage.
M14 raised start block / two entrances	High rear transition and deck, start flats, left/right roll-ins, windows, lattice/solid walls and upper roof/ceiling panels.
M15 big rail	Straight bar, bent bar, seven added posts, suppressed old plates, floor/drain, loose boards and two hidden grind paths.
High rail / SKATEBOARDING sign	Sign rod with original brackets, hanging sign faces and one hidden grind path; no added posts under the wall rod.
Deck rail	East bar, three added posts, two suppressed old plates and one hidden grind path.
Box piles / letters / tape / bonus icons	Fourteen actual game placements from final generator transforms; extracted goal-pile nodes are not wooden crate geometry.
Window wall / brick and graffiti walls	Spatial wall panels, textured window bands and independently assigned sign/poster/graffiti overlays. Source transparency is retained.
Ceiling / trusses / lamp / crane	Source upper roof/ceiling panels, ten ceiling/room diagonal braces, chains, crane hook, lamp, pillar sections and added spill roof panels.
Remake cones, barricades, truck, door splinters, sunlight shafts	No separate source objects or generator placements identified. Do not invent instances from video-only details; the source partition still covers every face.

This is a source/measurement audit. The kit’s palette listing, search, thumbnails, placement at world scale, selection, rotation, drag-move, removal and undo/redo were checked in the running editor through the dev harness for a prop, a window and an added piece. Attachment checks cover owner transforms, independent support edits, deletion/undo, isolated copies and saved replay. The three main north transition modules hand off grinds across their split coping paths; the relocated window remains collision-open while its frame stays solid. Visual equivalence and joint collision throughout a complete assembled level remain open. The preservation check guards the shipped Warehouse throughout.
