Base triangles dropped from 6616 to 2988 in the quality pass: overlapping face boxes and a beveled superellipse horn became one slotted slab plus a circular oval loft. Hidden coincident faces were the waste.

DECIMATE COLLAPSE triangle counts are not identical across series — the gate is a ratio band, not an exact count. Bake pixels are stochastic; the gate is has_data plus operator FINISHED, not byte-identity. Stave-width jitter uses fixed seed 17, and the per-piece wood tone its own seed. Export byte counts differ on 5.2.1 (glTF serializer), not a gated axis.

The collider is the convex hull of the whole piece; its count is carried by the 96-segment turf outline.

Every falsifier leaves the triangle count at 42908 and the AABB unchanged: they move parts or change a length, never add or remove geometry.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. Construction uses only seeded random.Random streams; two default runs print identical measurements.

Bamboo Clump

Intended size: a clump 3.82 × 3.55 m across its leaves and 4.83 m to the highest leaf. The outer AABB is 3.8168 × 3.5512 × 4.8254 m, read off the vertices: the leaning culms and their branches set X and Y, a leaf on the tallest culm's top plume sets the top; the soil's underside is the ground. The collider is the convex hull of the lower 1.25 m of the clump, coarse: a player walks the litter and brushes through the leaves, but not through the culms.

The quality pass re-fitted four of these around the new measurements, each for a stated reason. The triangle band moved from 51500–53500 to 72800–74800, paying for a fuller crown (815 leaves on 107 branches against 567 on 63), 21 culm sheaths, five knuckles and a wax-band row under every node. The face floors follow the same counts. The collider ceiling went from 80 to 96: the culms now rise from a 0.6 m footprint and splay from the soil, so the hull of the lower 1.25 m has more facets (88). The AABB is a new shape.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. The plan is seeded and nothing else is random; the geometry is pure Python math. Two default runs print identical measurements.

Basketball Hoop

Shading follows what each part is. Round stock (ring, cord, balls, braces) is smooth-shaded. Chamfers, material boundaries and bends over 35° stay sharp, and so does a flat face meeting a much narrower facet, so the pole's flats read flat and its corner fillets read round. The steel is near-black satin powder coat and the frame satin aluminium, each with a studio reflection term in the material (after espresso-machine), so neither reads as grey plastic on the dark stage.

It asserts budget conformance of the generated result. It does not witness an API contract. "It rendered without error" is not a check.

No falsifier changes the triangle count or the envelope: every falsifier run measured 40244 tris and the default's outer AABB to the tenth of a millimetre.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. The plan is seeded and nothing else is random; the geometry is pure Python math. Two default runs print identical measurements.

Every falsifier leaves the triangle count at 37078 and the envelope at (1.6400, 2.3014, 0.5234): they move or resize parts, never add or remove geometry.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. The ball's Boolean may cut its sphere into a slightly different set of faces on another series; the triangle band and the ball and bore floors leave room for it. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. Construction uses no RNG; two default runs print identical measurements.

The collider is the convex hull of the bole alone: a 14-sided frustum from under the soil to the fork and a point over the dome, without flutes, buttresses or roots, because players walk under the crown. The hull is built from points only; handed faces as well, it keeps them alongside its own.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count (4.5.11 and 5.1.2 decimate to 0.5000 / 0.2200). Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. The plan is seeded and nothing else is random; two default runs print identical measurements, and 4.5.11 and 5.1.2 print the same measurements as 5.2.1 apart from the LOD counts (the glTF differs by 20 bytes).

Cactus Garden

Intended size: a disc 3.00 × 2.61 m, its mound 0.14 m high, the saguaro's crown flowers 2.38 m off the floor. The outer AABB is 2.9950 × 2.6077 × 2.3754 m, read off the vertices. The sand sets X and Y, a crown flower the top; the sand's underside is the ground. The collider is the convex hull of the sand disc alone, coarse: players brush through the plants.

Base triangles dropped from 3616 to 2200 in the quality pass: the old piece stacked identical boxes with a mortar gap and a teepee that met at one point. The rebuild is two seated courses plus crossing sticks; hidden overlapping volume went away. The second pass took it to 2760: each stone is now a lofted, chamfered lump instead of a four-sided wedge.

DECIMATE COLLAPSE triangle counts are not guaranteed identical across series — the gate is a ratio band, not an exact count. Bake pixels are stochastic; the gate is has_data plus operator FINISHED, not byte-identity. Stone-width jitter uses fixed seed 17; each stone's shape draws from its own seeded generator. glTF byte size differs on 5.2.1.

The collider is the convex hull of the whole loader; the power pack, the beacon, the shoulder pins and the tine tips carry its outline.

Every falsifier leaves the triangle count at 44600 and the outer AABB unchanged: they move, turn or reweigh parts, never add or remove them.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. Construction uses no RNG; two default runs print identical measurements.

The triangle band is centred on that measurement, ± 4 %. The axe-head reprofile (a waist behind the eye) added one head section: 1800 → 1816.

Real-world size: each crate is 0.58 × 0.42 m at the timber and 0.588 × 0.428 m over the corner iron and its nail heads, 0.244 m tall including runners and lid. Three stacked come to 0.70 m — knee height, wider than tall.

Why the footprint is measured in the crate's own frame#

The stack AABB is the union of three yawed boxes, so a crate could drift to any size underneath it and the outer budget would not notice. Each crate's footprint is therefore measured after un-rotating by the yaw that crate was measured to have, not the yaw it was built with. All three land on 0.5882 × 0.4282 m exactly, which is what makes the un-rotation trustworthy.

Desk Lamp

Intended size: a 0.18 m square base, 0.32 m and 0.36 m arm sections, and a shade 0.17 m across the rim. The outer AABB is 0.725 × 0.361 × 0.442 m. The shade rim sets +X, the plug sets −X and −Y, and the elbow knuckle sets the top. The origin is under the base centre, so the lamp drops onto a desk by its base.

The triangle band is wide enough to hold --hollow-base (30974) and --unhook-spring (29790), so those falsifiers exit on their own budgets rather than on the triangle count.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. Construction uses no RNG; two default runs print identical measurements.

No falsifier changes the topology, so every one of them measures the default's 43636 triangles. Every one keeps the default's AABB except --sink-cup, which sinks the cup that sets the top 3 mm and measures 0.4725 m, inside the 10 mm tolerance.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. Construction uses no RNG; two default runs print identical measurements.

Fallen Log

Intended size: a log 3.60 m long to the tip of its longest splinter, its top 0.67 m off the ground, on a soil mound 4.12 × 2.17 m. The outer AABB is 4.119 × 2.189 × 1.027 m. The soil sets X and the south edge, the tip of one fern frond the north edge, and the upright stub's broken tip the top. The soil's underside is the ground. The collider is the convex hull of the log alone, round and unfurrowed: players walk through ferns.

Base triangles dropped from 1092 to 1012 in the second quality pass. Each band became one mitred shell instead of three or four separate plates, and the brace became a six-face board. The band was re-fitted around the measurement and narrowed from 1000–1400.

DECIMATE COLLAPSE triangle counts are not identical across series: 5.2.1 is more aggressive on LOD2. The gate is a ratio band, not an exact count. Bake pixels are stochastic; the gate is has_data plus operator FINISHED, not byte-identity. Construction is closed-form and plank tones are seeded, so repeated runs on one binary print identical measurements. Export byte counts differ by 12 B on 5.2.1 (glTF serializer), not a gated axis.

The piece is 86,740 triangles, 58% of them pinnae; the boulder's lattice went from 28 to 36 cells a side (16,224 stone faces) so its arrises are resolved at a 16–20 mm weathering radius instead of hidden in 40–110 mm bevels. A fern is its pinnae, and the whole point of this one is pinnule detail that holds up at hero size.

Floor Fan

Intended size: a 0.40 m base, a guard 0.452 m across its rim, and 1.23 m overall. The outer AABB is 0.761 × 0.704 × 1.229 m. The guard's rim sets the top, the guard and the cord's loop set the plan. The origin is under the base centre, so the fan drops onto a floor by its gasket.

No falsifier changes the topology, so every one of them measures the default's 41460 triangles and the default's AABB.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. Construction uses no RNG; two default runs print identical measurements.

Every falsifier leaves the triangle count at 81854 and the envelope at (1.8950, 1.7738, 0.6397): they move parts, never add or remove them.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. Construction uses no RNG; two default runs print identical measurements, and 4.5.11 and 5.1.2 print the same measurements as 5.2.1 (the export differs by 76 bytes).

The model pass took the pump from 1064 to 2412 triangles and raised the ceiling 2200 → 2600. Two lighting-and-paint passes had left it the plainest object in its asset sheet: a smooth two-step column on a box. It now carries the cast detail a village pump has: a turned lower barrel with a moulded foot and a spout boss, eight flutes on the upper barrel, a moulded collar at the socket, a domed cap and ball finial on the head, a rolled drip lip on the nozzle, a counterweighted tail on the handle, and a turned grip. A coopered bucket with two iron hoops stands under the spout, clear of the plinth. The spout's reach grew 0.13 → 0.17 m (SPOUT_R) so the nozzle clears the plinth and falls inside the bucket mouth. The outer AABB grew in y (0.382 → 0.521 m) for the bucket and in z (1.052 → 1.055 m) for the finial. The collider stays under its 220 ceiling because its source turns the bucket at 8 staves without hoops (BUCKET_PROXY_SEGS); at 16 staves the hull ran to 267, past Unity's 255 convex-collider limit. The foot (0.068 m) and spout boss (0.067 m) stay within COL_R_TOL of COL_R_LO, so the column-radius budget still reads the barrel. The flange classifier now also requires a shell centred on the column axis: the bucket's lower hoop is as wide and as low as the flange, and would otherwise mask --float-flange. The new bucket budget gets its own falsifier, --shift-bucket (exit 20).

Earlier, base triangles dropped from 1164 to 1064 in the quality pass: seven sausage cylinders became one gooseneck tube, and the wood grip is no longer beveled with the plinth. Outer AABB is 0.610 × 0.382 × 1.052 m (was 0.610 × 0.364 × 1.049 m).

DECIMATE COLLAPSE triangle counts are not identical across series — 5.2.1 is slightly leaner on LOD2. The gate is a ratio band, not an exact count. Bake pixels are stochastic; the gate is has_data plus operator FINISHED, not byte-identity. Construction is closed-form; the only RNG is the seeded per-piece wood tone. Bevel inputs are sorted by edge index, so the face order is the same on every run; a Python set of edges handed to the bevel had made it vary. Export byte counts differ on 5.2.1 (glTF serializer), not a gated axis.

DECIMATE COLLAPSE triangle counts are not guaranteed identical across series — the gate is a ratio band, not an exact count. Bake pixels are stochastic; the gate is has_data plus operator FINISHED, not byte-identity, plus the texel floor. The bake was 256 px, which left 5.6 texels per UV cell and smeared neighbouring cells' normals into streaks across the straw; at 1024 px with a 0.02 m cage (was 0.04, which reached the twine standing proud of the loaf) every cell gets 22. Export byte counts differ by 12 B on 5.2.1 (glTF serializer), which is not a gated axis; every geometric figure above is identical on all three binaries.

The export is deleted once its size is measured. Blender sets TMPDIR from its own preference, which resolves to the working directory on a stock portable build, so tempfile.gettempdir() is the repo root under CI and every run used to leave a .glb behind.

Base triangles rose from 1598 to 1680. The old rings were faceted tori clipped into the arm; the new eyes, shanks, and 24-segment hung rings replace that mesh. Cylinder caps are triangulated so the n-gon budget stays at 0.

DECIMATE COLLAPSE triangle counts are not identical across series — the gate is a ratio band, not an exact count. On this mesh the three binaries agreed. Bake pixels are stochastic; the gate is has_data plus operator FINISHED, not byte-identity. Construction is closed-form; the only RNG is the seeded per-piece wood tone. Bevel inputs are sorted by edge index, so the face order is the same on every run; a Python set of edges handed to the bevel had made it vary. Export byte counts differ on 5.2.1 (glTF serializer), not a gated axis. Euler is 14 (12 before the horseshoe added one more closed shell) and is not gated to 2.

Hover Bike

Intended size: 2.23 m long, 0.66 m across the bar ends, 1.11 m to the top of the cluster's visor, with the saddle's top at 0.852 m. The shrouds set the length, the bar-end weights the width and the visor the top. The fuselage is 1.033 × 0.344 m. The origin is under the bike's centre, so it lands on the soles of its wear strips.

The collider is the convex hull of the whole bike. Its count is carried by the two 72-segment shroud lips, which are the hull's outline in plan.

Every falsifier leaves the triangle count at 45796: they move, scale or bend parts, never add or remove them.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. Construction uses no RNG; two default runs print identical measurements.

Archery Target

archery-target

A procedural archery range target on a turf patch — a 1.10 m compressed-straw boss coiled from rope courses that show on its back and round its edge, bound with doubled jute twine drawn tight over the crests; an 80 cm ten-zone World Archery face in aged inks with ring lines, an X ring and a printed X, held by four target pins; a timber easel leaning it back 12° on toe skids with knee braces, a ledge with a stop lip on a bolted rail and gussets, a numbered butt board, a strap hinge pinned to a rear leg in a steel ferrule and foot, and a splay chain between eye bolts; five carbon arrows in the face with cresting, nocks and three vanes, one glancing into the straw edge, one snapped with its fletched half on the grass, and a leather quiver of arrows lying among grass tufts — through UVs, bake, LOD, collider, and Unity glTF, asserting recomputed budgets rather than an API contract.

Planet Rover

planet-rover

A procedural six-wheeled planetary science rover in the rocker-bogie tradition on a patch of rocky red-grey regolith — a cream warm-electronics body with gold-foil insulation blankets quilted into puffed cells, anodised corner posts and a trimmed deck carrying instrument boxes, sample inlets, a calibration target, a UHF can and a whip; a finned radioisotope power unit on struts between two radiator fin banks; on each side a rocker pivoting on a boss in the body side through its eye and pin, and a bogie pinned in a clevis on its front end, the two rockers linked through cranks and links to a differential bar on the deck so they turn equal and opposite; six 0.50 m aluminium drum wheels with 24 chevron grousers, six curved titanium flexure spokes and a drive actuator each, the four corners hanging from steering actuators through C-brackets; a camera mast with a laser telescope window, two camera barrels and navigation cameras; a high-gain dish on a two-axis gimbal; a 5-DOF arm whose turret drills a boulder; cable harnesses along every leg, the mast and the arm; ruts trailing behind both wheel lines and 19 broken rocks, the regolith fitted so every wheel sinks into it — through UVs, bake, LOD, collider, and Unity glTF, asserting recomputed budgets rather than an API contract.

Base triangles rose from 3388 to 3664 in the quality pass: coaxial ferrule cups and a dual-wall lathe with a rolled rim replaced the old cone-tripod / overlapping-torus construction. The #345 remodel (the asset sheet read it as the least-designed object in the lineup) took it to 4180: a five-link chain replaced the bare hanging rod, a forged iron head replaced the turned wooden crown, and the pot gained a casting band and three stub feet. The iron material breaks its rust into blotches and adds fine sand-cast pitting. 4180 leaves 20 triangles under the ceiling, enough for --short-legs's 12-triangle shim to still land on the support check (16), not the triangle budget (4).

The collider is the convex hull of the whole scooter; the mudguard, the mirrors and the tail carry its outline.

Every falsifier leaves the triangle count at 45060 and the outer AABB unchanged: they move, turn or bend parts, never add or remove them.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. Construction uses no RNG; two default runs print identical measurements.

Mushroom Stump

Intended size: a stump 0.62 m across the bark at the cut, sawn 0.50 m above the soil at its axis, on a soil disc 1.7 × 1.6 m. The outer AABB is 1.935 × 1.628 × 0.689 m. Two fern fronds set X, the soil sets Y, and the tallest hinge fibre the top. The soil's underside is the ground. The collider is the convex hull of the stump alone, round and unfurrowed, down to the soil: players walk through ferns and step over roots.

No falsifier changes the triangle count, and only --tall-hinge moves the envelope, 7.2 mm up against the 10 mm tolerance: they move parts or reshape the foot, never add or remove faces. The upper lathe carries a fixed ring count, so moving the foot keeps the topology; the step's chord scales with --fat-stump, so the cuts along it cross the same edges.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. The plan is seeded and nothing else is random; two default runs print identical measurements, and 4.5.11 and 5.1.2 print the same measurements as 5.2.1 (the glTF differs by 16 bytes).

Intended size: seat 0.50 m high, a 0.66 m star, armrests 0.20 m over the seat, headrest top 1.32 m; a 1.20 × 1.28 m mat plus its 0.20 m lip; a planter 0.29 m tall with leaves to 0.96 m. The outer AABB is 1.635 × 1.480 × 1.317 m. The mat sets −X and ±Y, the plant sets +X, the headrest sets the top. The origin is under the hub, so the chair and its mat drop onto a floor together.

Budgets#

Every budget is declared as a named constant. Every gate recomputes its value from the mesh, materials, UVs, evaluated LOD, collider, or export file. Parts are told apart by a part face attribute written at build time; every position, depth, angle and mass is read off the mesh.

No falsifier changes the triangle count, so the band is narrow and centred on the measurement. DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. Construction uses no RNG; the plant's per-blade variation is closed-form from the blade index. Two default runs print identical measurements.

Palm Tree

Intended size: a disc 3.1 × 2.8 m, the palm 6.03 m to the tip of its highest frond. The outer AABB is 5.2645 × 5.1503 × 6.0258 m, read off the vertices: the fronds set X, Y and the top; the sand's underside is the ground. The collider is the convex hull of the lower 2.4 m of the trunk, coarse: players walk the sand and brush through the fronds, but not through the bole.

No falsifier changes the triangle count: every falsifier run measured 45196 tris. None moves the envelope by more than 0.1 mm.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. The plan is seeded and nothing else is random; the geometry is pure Python math. Two default runs print identical measurements.

Base triangles rose from 2520 to 3272 in the second quality pass. The square posts and 6-gon scroll tubes became 8-gon round bar swept along each leg, the back gained its bend, and armrest brackets were added. The band was re-fitted around the measurement and narrowed from 2200–4200.

DECIMATE COLLAPSE triangle counts are not guaranteed identical across series — the gate is a ratio band, not an exact count. This mesh matched on 4.5.11 / 5.1.2 / 5.2.1. Bake pixels are stochastic; the gate is has_data plus operator FINISHED, not byte-identity. Slat widths are closed-form and plank tones are seeded, so repeated runs on one binary print identical measurements. Export byte counts differ by 16 B on 5.2.1 (glTF serializer), not a gated axis.

Every falsifier leaves the triangle count at 46096: they move parts, never add or remove them. DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. The low mesh is baked against a high copy whose edges over 35° are bevelled in three segments. The rocks' shapes come from a seeded random.Random; everything else is closed-form, and two default runs print identical measurements (and an identical export size).

Intended size: a disc 3.20 × 2.63 m with its bank 0.17–0.25 m high, the tallest cattail spike 1.51 m off the floor. The outer AABB is 3.204 × 2.634 × 1.507 m, read off the vertices. The soil sets X and Y, a cattail spike the top; the soil's underside is the ground. The collider is the convex hull of the soil disc alone, coarse: the water is a trigger volume, and players walk through reeds.

No falsifier changes the triangle count or the envelope: every falsifier run measured 37602 tris and the default's outer AABB to the tenth of a millimetre.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. The plan is seeded and nothing else is random; the geometry is pure Python math. Two default runs print identical measurements.

DECIMATE COLLAPSE triangle counts are not identical across series — 5.2.1 is leaner on LOD1 and LOD2. The gate is a ratio band, not an exact count. Bake pixels are stochastic; the gate is has_data plus operator FINISHED, not byte-identity. Construction is closed-form; the only RNG is the seeded per-piece wood tone.

Measuring it took two correctionsThe first attempt selected intrados vertices by radius. That swept in the chamfer vertices sitting one bevel-width out on each radial face and reported a 5.1 mm error on a true arch. The fit now runs over the vertices of faces that actually face the springing centre — normal inward in XZ and with a small Y component, which is what excludes the chamfer strips running along the intrados edges.

Mortar#

Every joint used to be air. The pier courses stood 7 mm apart and the voussoirs 9.7 mm apart, none of them touching: each pier was a stack of floating blocks, with daylight through every joint in the ground-contact and joint close-ups. The mortar-band budget measured the gaps and passed, because the gaps were the right width. Nothing asked what was in them.

DECIMATE COLLAPSE triangle counts are not guaranteed identical across series — the gate is a ratio band, not an exact count. This mesh happened to match on 4.5.11 / 5.1.2 / 5.2.1. Bake pixels are stochastic; the gate is has_data plus operator FINISHED, not byte-identity. Construction uses no RNG; the per-piece material tone is drawn from a seeded random.Random(TONE_SEED), the same every run. glTF byte size differs by a few hundred bytes across series; the gate is "written and non-empty", not a byte count, and the file is removed once measured.

Base triangles dropped from 3520 to 3338 in the first quality pass (closed square-pyramid roof, unshared cage crossings, pane rebate), then rose to 4726 when the model gained its column flutes, second collar, ladder bar, arm scrolls, hook ring, eave band, base tray and drip. The band moved from 3000–3800 to 4200–5200, the same ~±10 % slack around the measured count. The 5.1.2 column was dropped with this change: the new model was measured on 4.5.11 and 5.2.1 only.

DECIMATE COLLAPSE triangle counts are not identical across series — 5.2.1 is 8 tris leaner on LOD2. The gate is a ratio band, not an exact count. Bake pixels are stochastic; the gate is has_data plus operator FINISHED, not byte-identity. Construction uses no RNG. Export byte counts differ by 16 B on 5.2.1 (glTF serializer), not a gated axis.

Base triangles rose from 2528 to 3040 in the second quality pass, and the band moved from 2300–3200 to 2750–3350. Each foot gained a tread, and the sleeves are walled on both ends. The bake went from 256 px to 1024 px, and its cage extrusion from 60 mm to 10 mm. See the bake texel budget below.

DECIMATE COLLAPSE triangle counts are not identical across series. The gate is a ratio band, not an exact count. Bake pixels are stochastic; the gate is has_data plus operator FINISHED, not byte-identity. Construction is closed-form and member tones are seeded, so repeated runs on one binary print identical measurements. Export byte counts may differ by a few bytes across series.

Terrain Scatter

Hero. On the render path, grass is blended into the dirt shader where the ground faces up (geometry normal Z), broken by a coarse patch noise so bare soil shows through. The rounded rim and the cut sides tip past the band, so the section still reads as topsoil over subsoil. A render-only dressing, drawn with a fixed seed from the up-facing dirt faces, adds 120 clumped grass tufts and 40 sunk pebbles in the stone material. The dressing is staging, parented to the tile, and is not part of the asset, its budgets or its export. The asset sheet judges TerrainLow alone.

Base triangles rose from 1194 to 1758 in the first quality pass: 9-vert hill became a 21-vert grid, and bevelled cubes became subdiv-2 icospheres. Outer Z dropped from 0.655 m (crate corners swinging through the slab) to 0.552 m of seated stone on the hill.

The second pass took them from 1758 to 2398: the four-segment rim bevel adds 640. The outer Z moved from 0.584 m to 0.570 m, because the stones now sink into the ground rather than perch on it, and the declared size was re-fitted to match. The collider fell from 72 to 36 triangles because it now hulls a coarse, unbevelled 9-vertex tile (COLLIDER_GRID): the chamfer and micro-relief are visual, and on the full-resolution tile they pushed the hull to 178, over its ceiling.

Every falsifier leaves the triangle count at 45816 and the envelope at (3.0365, 2.0374, 1.3354): they move parts, never add or remove them.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. Construction uses no RNG; two default runs print identical measurements, and 4.5.11 and 5.1.2 print the same measurements as 5.2.1 (the export differs by 28 bytes).

Base triangles rose from 1528 to 2004 in the second quality pass, and the band moved from 1400–1700 to 1800–2250. The solid cup became an open, walled cup with a drip boss. The 26 mm haft stub became a 0.20 m haft with a wrap. The three flame cones became lathed teardrops. The envelope grew from 0.293 m to 0.322 m in depth and from 0.424 m to 0.485 m in height, because the torch now stands up out of its cup.

DECIMATE COLLAPSE triangle counts are not identical across series. The gate is a ratio band, not an exact count. Bake pixels are stochastic; the gate is has_data plus operator FINISHED, not byte-identity. Construction is closed-form and stone tones are seeded, so repeated runs on one binary print identical measurements. Export byte counts differ by 24 B on 5.2.1 (glTF serializer), not a gated axis.

Base triangles rose from 2484 to 3700 in the first quality pass: box end slabs and a single extruded U became ten jittered staves, U end-caps, continuous straps offset from the legs, and stretchers that meet the inner faces. The second pass took them to 3124: the open U-band ends became solid end boards, which close the section with fewer faces. The third pass took them to 3316: each end became three boards. The fifth pass took them to 4792: the water became a lofted, rippled volume (~900 triangles; it was one flat quad on a U prism), and the straps gained ten bolt heads and four rim clips, the trestles six pegs, and the right end a bung. The band moved from 2800–3500 to 4300–5200, the same ~±10 % slack around the measured count. The collider hulls the trough without the sub-2 cm hardware (bolts, pegs, bung): detail that small carries no collision meaning. The rim clips are 47 mm wide and stay in it. The 5.1.2 column was dropped with this change: the new model was measured on 4.5.11 and 5.2.1 only.

DECIMATE COLLAPSE triangle counts are not identical across series — the gate is a ratio band, not an exact count. Bake pixels are stochastic; the gate is has_data plus operator FINISHED, not byte-identity. Stave-width jitter uses closed-form sin(i); plank tone is the only RNG, seeded (TONE_SEED). Export byte counts differ by 16 B on 5.2.1 (glTF serializer), not a gated axis.

The hull-size budget (exit 19) runs before the outer AABB budget (exit 8) so --narrow-hull is not swallowed by a moved bounding box.

The collider is the convex hull of the whole set. Its count is carried by the plates' rims and the dumbbell heads, which are the hull's outline.

Every falsifier leaves the triangle count at 44264: they move parts or swap a plate for one of the same topology, never add or remove geometry.

DECIMATE COLLAPSE triangle counts are not identical across Blender series, so the LOD gate is a ratio band, not an exact count. Bake pixels are stochastic, so the bake gate is has_data plus operator FINISHED, not byte-identity. Construction uses no RNG; two default runs print identical measurements.

Base triangles rose from 936 to 2536. The previous mesh was two boxes, six cloned dowels, and four chrome cubes. Turned rungs (tenon and barrel in one shell) plus ferrule collars and chamfered soles added the triangles. Nothing was removed as a hidden face.

A later pass took them to 2680. The bare ladder was still the plainest object in its asset-sheet lineup, and the parts budget is exact (16 shells), so the detail had to live inside existing shells. Each rung gained one ring at mid-span (+24 triangles per rung): the barrel shoulders in at 0.90 × its radius (RUNG_SHOULDER) and swells to 1.14 × (RUNG_SWELL). That turns a dowel into a lathe-turned round. The tenons are unchanged, so clearance, engagement and pitch read the same. The breakout margin moved 0.07 mm (0.03780 → 0.03787) because the shell's worst vertex is now measured across seven rings. The wood shader also changed. The grain noise runs across the stile's 50 mm width at a readable scale (WOOD_GRAIN_SCALE 34 → 95, streak stretch 0.94 → 0.985); before, about one noise period spanned a stile, so it rendered as flat tan. A short-range AO term darkens the rung housings and the wood under the iron sleeves.

A third pass changed the model itself. The bare ladder was still the plainest object in its asset sheet, because the exact parts budget left every detail inside the existing shells. The parts budget is now 26: two iron tie-rods run through both rails under the bottom and top rungs, each end clamped by a square nut over a round washer bedded on the rail's outer face. That is the rod a wooden ladder carries to stop the rails spreading off the rungs. The triangle ceiling rose 2800 → 3100 for the hardware (+320 triangles; the old ceiling had 120 to spare). The rungs are now through-tenoned: each tenon runs right through its rail and stands 2 mm proud, so the old breakout margin (a blind tenon stopping short of the outer face) became a through-tenon proud band, and the tenon's inboard ring moved to 4 mm inside the rail so the joint audit always samples tenon section in the wood. The shader reads a per-shell Species attribute: rungs are pale hickory against darker oak rails, and end grain (the tenon ends, the rail tops) takes the finish darker. The rung finders now require the wood material, because the tie-rods are as wide as a rung. The new tie-rod seat budget gets its own falsifier, --float-nuts (exit 20).
