+# Blender asset library
+
+Status: built and audited (2026-11-01). Nothing in the game loads these assets yet.
+They are staged for the Phase 3.5 integration in
+[`plan-graphics-v0.6.md`](plan-graphics-v0.6.md).
+
+Generator: [`tools/blender_assets.py`](../tools/blender_assets.py). Manifest (the
+source of truth for integration):
+[`assets/models/blender/manifest.json`](../assets/models/blender/manifest.json).
+
+## Art direction
+
+The references were the AI mockups in `docs/screens/designs/` and the current
+captures in `docs/screenshots/`.
+
+- **People** (`targeting_npc`, `joke_shop_queue`, `studio_arrival`,
+  `crowd_panic`, `responder_arrival`): ordinary adults in sweaters, jackets,
+  long coats, hoodies and beanies; a security guard in a dark uniform with a cap
+  and belt; a firefighter in a dark turnout coat with yellow reflective bands,
+  a helmet and an SCBA tank. The current skinned `npc_base` is a set of boxes
+  and cylinders with a flat face, so silhouette was the main gap.
+- **Props** (`prop_gallery`, `venue_overview`, `late_night_avenue`,
+  `joke_shop_queue`): the gallery mockup has an octagonal tapered bollard, a
+  slatted bench with thin metal legs, an octagonal green litter bin with a slot
+  and recessed panels, a stone planter with a lumpy shrub, a blue news box with
+  a window and a slanted top, and a hydrant with caps and nozzles. The venue
+  shots add ornate street lamps, palm trees, round stone pots with topiary, a
+  chalkboard A-frame sign, a wall lantern, a bulb-lit marquee, glazed double
+  doors, stair handrails and a dark sedan. Today's in-game props are primitive
+  boxes, and the trees are cones.
+
+## Running it
+
+```bash
+# Build every asset (or --only a,b,c). Writes GLBs, .blend sources, manifest.
+flatpak run org.blender.Blender --background \
+  --python "$PWD/tools/blender_assets.py" -- build
+# Cycles previews (CPU, ~3 s each) -> docs/blender_previews/<name>.png (gitignored)
+flatpak run org.blender.Blender --background \
+  --python "$PWD/tools/blender_assets.py" -- render
+python3 tools/blender_assets.py sheet   # -> docs/blender_previews/sheet_<category>.jpg
+python3 tools/blender_assets.py audit   # stdlib only; exit 1 on any issue
+python3 tools/blender_assets.py list
+godot --headless --path . --import      # after any rebuild
+```
+
+The flatpak cannot read `/tmp` and its cwd is `/app/blender`, so the script
+derives every path from its own location. A full build takes about 5 s; a full
+render about 2.5 min.
+
+## Layout
+
+| Kind | Path | Count |
+| --- | --- | --- |
+| Characters (skinned) | `assets/models/blender/npc/<name>.glb` | 8 |
+| Gear (static) | `assets/models/blender/npc_gear/<name>.glb` | 18 |
+| Props (static) | `assets/models/blender/props/<name>.glb` | 20 |

+| Review sheets | `docs/blender_previews/sheet_{npc,npc_gear,props}.jpg` | 3 |
+
+## Conventions
+
+- Blender is Z-up. The glTF exporter converts to Godot Y-up.
+- **Front = Blender −Y = Godot +Z**, the face direction that
+  `NpcAvatar.yaw_towards()` assumes.
+- Grounded assets have their origin on the floor (`min y ≈ 0`). The two
+  exceptions are `wall_lantern` (origin on the wall plate, at mount height) and
+  `marquee` (origin at the wall where the canopy meets it, at canopy height).
+- Units are metres, at the same scale as the current world (1.82 m characters).
+
+## Characters
+
+All eight use the `npc_base` contract, so each one can replace
+`npc_base.glb` without code changes:
+
+- mesh node `npc_base` under an armature that imports as `Skeleton3D`
+- bones `Head`, `HipL/R`, `KneeL/R`, `ShoulderL/R`, `ElbowL/R`, `HandL/R`
+  (plus `Hips`, `Spine`, `Neck`) at the **same rest positions as `npc_base`**.
+  `test_character_joints_line_up_with_npc_base` checks this within 1 cm, so the
+  animation proxies in `_build_skinned_body()` stay valid.
+- material slots `skin`, `cloth`, `pants`, `accessory`, `hair` carry the same
+  neutral `assets/textures/npc/<slot>_{albedo,normal}.png` maps, so
+  `Materials.npc_slot()` tints them the same way it tints `npc_base`.
+- budget ≤ 6000 triangles and ≤ 4000 vertices (glTF vertex count, after seam
+  splits). The current range is 3,788–4,640 triangles and 3,200–3,960
+  vertices.
+
+Construction: the torso and limbs are one continuous Skin-modifier mesh,
+subdivided twice, decimated to 36 % with X symmetry, and cut at the waist, cuffs,
+sleeves and neck so the material borders are clean edge loops. The head,
+face (nose, ears, eyes, brows, mouth), hair, hands, shoes and clothing layers are
+separate parts. Weights come from distance to the bone segments, limited by body
+region. Parts that should stay rigid (head, hands, shoes) get a single bone.
+

+| `npc_hoodie` | `hood` accessory: hood up, beard, pocket | trespasser, mental crisis, violent threat | cup |
+| `npc_firefighter` | responder: broad build, banded turnout coat, boots | responder | helmet, SCBA tank, flashlight |
+| `npc_guard` | uniform: belt, buckle, badge, shoulder patches, radio | player guard / venue security | cap, wand |
+
+**Fixed-colour materials.** Detail materials outside the five slots (`hivis`,
+`reflective`, `leather`, `steel`, `patch`, `plastic_black`, `rubber`) carry a 4×4
+colour texture. The current `_apply_outfit_materials()` sets
+`albedo_color = WHITE` on any slot it does not recognise, and these keep their
+colour through that. When integrating, tint only the five contract slots.
+
+**Runtime tint notes.** `_build_skinned_body()` currently paints `cloth`
+hi-vis yellow for the `vest` layer. On `npc_vest` the vest is already the fixed
+`hivis` material and `cloth` is the undershirt, so skip that override for this
+model. For `npc_firefighter` and `npc_guard`, tint `cloth`/`pants` dark (turnout /
+uniform navy) and not with the role's `TYPE_COLORS`.
+
+## Gear attach points
+
+Gear is authored in attach-point space, so the origin of each GLB is its
+attach point:
+
+| Attach | Godot parent / position | Gear |
+| --- | --- | --- |
+| `head` | `Rig/Head` marker (0, 1.62, 0) | cap, beanie, hood, sunglasses, firefighter_helmet |
+| `back` | `Rig` at (0, 1.10, 0), spine centre; items sit behind the body (Blender +Y = Godot −Z) | backpack, shoulder_bag, scba_tank |
+| `chest` | `Rig` at (0, 1.30, 0), sternum | lanyard |
+| `hand` | Hand proxy (±0.27, 0.78, 0.02); grip 5 cm below the origin | phone, cup, clipboard, umbrella, camera, protest_sign, flashlight, wand, radio |
+
+The character previews in `sheet_npc.jpg` are built by importing the gear at
+exactly these points, which gives a quick visual check of the convention.
+
+## Props
+
+| Prop | Replaces / role | Notes |
+| --- | --- | --- |
+| `bollard`, `bench`, `trash_bin`, `planter_box`, `newspaper_box`, `fire_hydrant` | `assets/models/generated/<name>.glb` | same footprint and height as the generated set, so colliders and `PROP_PLACEMENTS` still fit |
+| `street_lamp` | the box lamps in `_build_street_furniture()` | 5 m; the arm points to −X with the bulb at (−0.85, 4.8, 0). Rotate 180° for the other side of the street. Emissive `bulb` |
+| `street_tree` | the cone trees | 3.6 m, with a tree grate |
+| `traffic_cone` | the `cone` prop accessory | 0.69 m |
+| `palm_tree` | new (boulevard) | 7 m, 14 fronds |
+| `round_planter` | new (mockup pots) | stone pot with topiary |
+| `a_frame_sign` | new (comedy club queue) | chalkboard |
+| `wall_lantern` | new (club door) | wall-mounted; emissive `bulb` |
+| `crowd_barrier`, `stanchion` | new (queue / crowd control) | 2.2 m bike-rack barricade; chrome post with velvet rope |
+| `handrail` | new (steps) | 2 m run that climbs 0.8 m along +X |
+| `security_podium` | new (door check-in) | tablet screen is mildly emissive |
+| `double_door` | the procedural entrance door | 2.0 × 2.7 m; emissive `lock_led` on the card reader |
+| `marquee` | the procedural marquee | 6 m canopy and sign box; emissive `bulb` + `sign_face`. Overlay the text with the existing `Label3D` |
+| `sedan` | new (studio arrival) | 4.6 m; emissive `headlight`, red tail lamps |
+
+Props use plain PBR factors (base colour, roughness, metallic, emission) and
+have no textures. They are not yet AO-baked; that is still a Phase 4 task.
+Emissive materials are always on in the GLB. The integration should tie them to
+`WorldBuilder.set_night_mode()`.
+
+## Checks
+
+- `python3 tools/blender_assets.py audit`: container, `POSITION`/`NORMAL`/
+  `TEXCOORD_0`, UVs in [0, 1], no zero-area triangles (Godot warns about them
+  during LOD generation), budgets (characters 6000/4000, gear 1500, props 4000
+  triangles), grounding, and an editable `.blend`. For characters it also
+  checks skinning, bones, slots, the `npc_base` mesh node and the height.
+- `tools/test_blender_assets.py`: catalogue and contract consistency with
+  `npc_pipeline.py`, plus a clean audit and full manifest coverage when the
+  library is built.
+- `src/test/tests/test_blender_assets.gd`: every asset imports as a scene
+  with geometry, characters keep their bones and slots, joints match
+  `npc_base`, the bones accept `NpcAvatar`'s pose composition, and props are
+  grounded.
+
+## Known limitations
+
+- The characters have no baked AO or ORM texture of their own. They reuse the
+  tiling slot maps, so the runtime `SurfaceMaterials` recipes still supply
+  roughness.
+- There is a single body topology per build (average, slim, broad) and no
+  shape keys. Height variety still comes from `outfit_for()["height_scale"]`.
+- Skirts and coats follow the hip and knee bones, so a full stride can clip
+  the legs through the hem.
+- Preview colours (`PREVIEW_TINTS`) only stand in for `outfit_for()`. The GLBs
+  stay neutral.
