# Clothing Pipeline â€” garment mesh â†’ game-ready outfit part

**What this is:** a headless-Blender pipeline that takes a clothing mesh from any
source (Marvelous Designer export, marketplace FBX/OBJ/GLB, hand-modeled) and turns
it into outfit-part GLBs that ariki-game characters actually wear â€” fitted to the
real body, reduced to game budget, skinned to the shared 65-bone Quaternius
skeleton, and registered in the game's `OutfitCatalog`.

Built 2026-07-30 after the CC5/Reallusion clothing lane was investigated and
rejected (CC5 provably refuses clothing tools on AccuRig "Humanoid" characters â€”
verified via its Python API *and* GUI; see `ariki-game` session notes). Everything
here is Blender-only, deterministic, and agent-drivable end to end.

## Why each stage exists

A downloaded garment is useless to the game for four reasons; the pipeline is the
four fixes in order:

| Problem | Fix | Stage |
|---|---|---|
| Not shaped like our character | Shrinkwrap-fit to the real body GLB (inflated "inner shell" target guarantees clearance) | `fit` |
| Millions of tris vs ~1.5k/part budget | Split by material into parts, rebuild/decimate, bake lost detail to normal+AO maps | `reduce`, `bake` |
| No idea how to move | Copy skin weights from the character's own body (special cone-proxy recipe for skirts) | `skin` |
| Game has never heard of it | Export per-slot GLBs on the shared skeleton + register in `OutfitCatalog` | `export` + manual catalog entry |

## Design decisions (and where they came from)

Reviewed by GLM-5.2 and glm-4.6 before implementation
(`../garments/glm-advice-glm52.md`, `../garments/glm-advice.md`) plus web research
on Marvelous Designer game workflows. Key adopted corrections:

1. **Fit BEFORE decimate, bake AFTER** â€” shrinkwrapping the high-poly garment
   molds real pleat geometry; fitting a faceted low-poly loses the silhouette.
2. **Pleated skirts are not decimated** â€” a clean low-poly cylinder proxy is
   generated and shrinkwrapped to the high-poly skirt; pleats live in the baked
   normal map (at 1.5k tris geometric pleats read as noise).
3. **Skirt weights come from a "cone proxy"** â€” a leg-bridging tapered cylinder
   weighted with a Z-gradient (body weights at waist â†’ pelvis-only at hem), then
   transferred to the skirt. Kills the hard left/right-leg seam that tears skirts
   in walk cycles. Forward-compatible with skirt bones later.
4. **Clearance via inner shell** â€” garments wrap to a ~4mm inflated copy of the
   body, not the body itself: mathematical clearance, not hope.
5. **Layer stacking** â€” bow wraps to bodice, bodice wraps to body shell
   (cumulative offsets), so layered cloth keeps separation.
6. **Weight transfer uses Data Transfer 'nearest face interpolated'**, not raw
   nearest-vertex KDTree (fails on overhangs like collars/bow tails).
7. Per-part tri budgets vary (bow ~400, bodice ~1200, skirt ~2200);
   verify in the game test bed EARLY (after skin), not at the end.

Sources also agree: if a garment came from Marvelous Designer, re-exporting from
MD with lower particle density / MD's own quad remesh skips the worst reduction
pain at the source. Prefer that when the .zprj is available.

## Files

| File | What |
|---|---|
| `garment_pipeline.py` | The whole pipeline. One Blender headless script, staged; each stage checkpoints a .blend into `work/` so stages can be re-run/iterated independently. |
| `configs/<garment>.json` | Per-garment recipe: source file, islandâ†’part mapping, slots, budgets, alignment, fit, cuts. The pipeline is data-driven; new garment = new config, not new code. |
| `work/` | Intermediates (checkpoint .blends, census data, QA renders). Disposable, gitignored. |
| `README.md` | This file. |

## Stages as-built (2026-07-30, after the dress pilot)

| Stage | What it does | Hard lessons baked in |
|---|---|---|
| `census` | Import garment, drop configured junk materials, weld, split into loose **islands**, render each in a distinct color + write `work/<name>/census.json` | MD material names lie (all fabric on one material; 4M faces were topstitch threads â†’ `drop_materials`). Parts are configured as island index lists, not material names. |
| `prepare` | Import body+rig, build configured parts from islands, **bodyshell** parts cut from the body itself, sleeve pose-warp (garment-local, pre-align), anisotropic align (`scale_xy`/`scale_z` â€” heroic bodies are wide, not tall), radial `torso_boost`, post-align `cut_above_z`/`cut_outboard_x`, `prune_scraps_x` (drop disconnected leftovers by centroid) | Fitted tops on a bust bigger than the garment shred under any shrinkwrap â€” use a **bodyshell** part (body region copy + normal offset, Islander technique): perfect fit and weights by construction. Cuts must run post-align in body space. |
| `fit` | Inflated `BODY_SHELL` (+4mm) target; shrinkwrap mode **OUTSIDE** (push out penetrating verts ONLY â€” never snap the whole cloth, that shreds layered garments) | `OUTSIDE_SURFACE` destroyed multi-layer bodices; `OUTSIDE` unmasked is safe everywhere since it can't pull cloth inward. |
| `reduce` | Keep `HI_<part>` copy for baking; `weld_band` fuses stacked layers (waistband/belt sandwiches) before decimation; planar dissolve â†’ collapse to per-part budget; optional cylinder proxy for standalone skirts | Decimating coincident stacked layers = swiss cheese; protecting zones from the decimator just moves the damage elsewhere â€” **weld the sandwich first**. |
| `bake` | (optional, Cycles) normals+AO from HI onto a second UV map | |
| `skin` | Data Transfer (nearest-face-interpolated) from body; `weights: dress` adds pelvis-gradient below hip so the hem doesn't tear between legs; bodyshell parts keep inherited weights; smooth+normalize; bind to RIG | |
| `export` | One GLB per outfit slot (multi-part slots joined by selection), full 65-bone armature included, vertex hash printed for determinism | |

## Current pilot

`configs/dress.json` â†’ `../garments/thin-unweld.fbx`: an MD dress ensemble
(2.49M verts, 12 materials). v1 scope: bodice + belt/bow (Body slot) + pleated
skirt (Legs slot). The sleeved jacket (`cape*` materials) is deferred â€” sleeves
need a pose-warp to T-pose (GLM advice Â§4 has the recipe) and is round two.
Unknown `Material*` slots are excluded pending the per-material stats `prepare`
prints; reassign them in the config if they turn out to be buttons/trim.

## Known limitations (v1)

- Skirt will still favor standing/dance poses; deep leg swings compress the hem
  (no skirt bones yet â€” the Z-gradient weights are ready for them later).
- Flat MD colors until someone supplies textures (bake stage produces normal+AO,
  not albedo).
- Body stays under garments (no hide-mask system in game yet) â€” clearance is the
  only poke-through defense; report tunnel-through in the test bed per animation.

# Marvelous Designer â€” agentic garment authoring

The **upstream half** of the clothing lane: reference image (or a description) â†’
sewn, draped, textured garment mesh fitted to the game body. The downstream half
(garment mesh â†’ game-ready skinned GLB) is `clothing/` â€” see
`.agents/wiki/architecture/clothing-lane.md` for how they meet.

Everything here was learned by doing it on 2026-07-30 (tee, skirt, kapa haka
pari + piupiu). The API facts are **verified against MD 2026 Personal**, not
docs â€” Reallusion/CLO's published API docs are thin and several signatures in
them are wrong.

## The 60-second model

- MD is driven through **`tools/md_bridge.py`** â†’ a socket plugin running inside
  MD (`tools/md_bridge/TinqsMDBridge.py`). Full protocol: `docs/md-bridge.md`.
- A garment = **flat 2D panels** (`CreatePatternWithPoints`) + **seams**
  (`AddSeamlinePairGroup`) + **arrangement points** on the avatar
  (`SetArrangement`), then **simulate** (`utility_api.Simulate(frames)`) to drape
  cloth onto the body.
- You see results by rendering the viewport to PNG (`ExportSnapshot3D`) and
  reading the image back. **This vision loop is the whole method** â€” draft,
  drape, look, measure, adjust, repeat.
- Garment identity for traditional wear is mostly **textiles, not tailoring**.
  Kapa haka / Mexica / Pacific garments are rectangles + blocks; the design lives
  in generated texture maps. Model the shape simply, spend effort on the pattern.

## Session protocol (read first â€” MD's UI freezes)

MD's embedded Python **does not run background threads**, so the bridge owns the
main thread while it serves. Consequences:

1. **A human must click** Plugin â†’ TinqsMDBridge to start a session. You cannot
   start one yourself. Ask, then wait.
2. **MD's UI is frozen** for the whole session ("Not Responding" is normal).
3. End with `python tools/md_bridge.py --stop` â€” works from the terminal even
   though the UI is dead. Idle timeout is 4 h (was 300 s; raised so one click
   lasts a work session).
4. **Pause the session whenever Jeremy wants to look at the model.** He inspects
   in MD's viewport; he can't while you hold the thread. Default to stopping when
   you hand back a result, unless he said to stay in.

```bash
python tools/md_bridge.py --ping                       # verify + see mode/api modules
python tools/md_bridge.py --exec "result = pattern_api.GetPatternCount()"
python tools/md_bridge.py --file tools/tailor/md_pari.py --timeout 500
python tools/md_bridge.py --stop                       # give the UI back
```

Long `Simulate()` calls need a raised client `--timeout` (~1 min per 300 frames).
The exec namespace persists **within** a session, not across; MD api modules
(`pattern_api`, `import_api`, `export_api`, `fabric_api`, `utility_api`,
`ApiTypes`) plus a `BRIDGE` info dict are pre-seeded.

**Introspect, don't trust docs.** Full surface dump lives at
`tools/md_bridge/api_surface.json` (688 functions) and harvested docstrings at
`tools/md_bridge/api_docs.json`. Overloaded pybind11 functions break
`inspect.signature()` â€” read `__doc__` instead.

## API facts that cost hours to find

| Fact | Consequence |
|---|---|
| **2D pattern y+ maps to UP in 3D** | Panels drafted y-down drape **upside-down over the head** and tangle. Symptom looks like a seam bug; it isn't. Hem at y=0, neckline at high y. |
| Units are **mm**; gravity âˆ’9800 | A "500" square is 50 cm. |
| Blender-exported FBX avatars import **10Ã— small** | Import with `op.scale = 10.0`. |
| `ImportAvatar()` is **.avt only** â€” returns `False` on FBX | Use **`import_api.ImportFBX(path, op)`** for the game body. |
| `op.bAddArrangementPoints = True` | Auto-generates ~98 named arrangement points on a custom avatar. Without it you have nowhere to hang cloth. |
| `SetArrangement()` only *assigns*; **`utility_api.ResetClothArrangement()` applies** it | Skipping the apply = nothing moves. (`ReDrape3DArrangement` only materializes not-yet-draped cloth.) |
| Arrangement **indices regenerate** per avatar import | Always look up by name from `GetArrangementList()`; never hardcode an index. Offsets aren't stable either â€” verify with a 0-frame snapshot. |
| Avatar getters live in **`export_api`** (`GetAvatarCount`, `GetAvatarNameList`) | Not `utility_api`, where you'd look. |
| `utility_api.NewProject()` **deletes the avatar** | Re-import after. |
| `SetBaseTextureMapImageGivenFilePath(path, fabricIdx)` â€” **path is arg0** | Reversed args throw a TypeError that reads like a missing overload. |
| **PNG DPI sets a texture's physical size in MD** | 1024 px at 54.2 dpi = 480 mm of cloth. Control tiling by setting dpi in PIL, not by scaling the image. |
| `fabric_api.AddFabric()` needs a **`.zfab` file path** | A name string silently fails. Stock presets: `C:\Users\Public\Documents\MarvelousDesigner\New Assets\Fabric\`. |
| Fabric **index 0 is the shared default** | Coloring it dyes every garment in the scene. Always `AddFabric` a new one. |
| `AssignFabricToPattern()` returns False for every arg order tried | Use **`pattern_api.SetPatternPieceFabricIndex(pattern, fabric)`**. |
| `SetViewPoint()` does nothing; **`SetCamViewPoint(2)` = front view** | Call before every QC snapshot so shots are comparable. |
| `GetClothPositions()` is an out-param that stays empty from Python | No mesh introspection â€” measure from rendered images instead (see QC). |
| No `SaveProjectFile`; no glTF export; no EveryWear in the API | Save = `export_api.ExportZPrj`. Exits: `ExportFBX` /

## Handing off downstream

Export three ways per garment, into `tools/tailor/`:

```python
export_api.ExportZPrj(".../lena_<garment>_v<N>.zprj")           # editable source of truth
op = ApiTypes.ImportExportOption(); op.bExportGarment = True; op.bExportAvatar = False
export_api.ExportFBX(".../lena_<garment>_v<N>_garment.fbx", op) # for clothing/
export_api.ExportOBJ(".../lena_<garment>_v<N>_garment.obj", op)
export_api.ExportZPac(".../lena_<garment>_v<N>.zpac")           # for outfit assembly
```

Then the garment goes through `clothing/garment_pipeline.py` (fit â†’ reduce â†’
skin â†’ export) to become a game outfit part. **Two advantages MD-authored
garments have over downloaded ones**, worth exploiting in the config:

- **They're already game budget.** These export at 1.2kâ€“3.7k verts; the
  downloaded MD dress the clothing pipeline was piloted on is 2.49 M verts /
  110 MB. The brutal `reduce` stage is mostly unnecessary â€” start with a high
  tri budget and only decimate if the test bed complains.
- **They're already fitted**, having been draped on the actual game body, so
  `align`/`fit` needs little more than the clearance shell.

Keep the `.zprj` â€” regenerating a variant beats re-authoring, and the clothing
README explicitly prefers re-exporting from MD over fighting reduction.

Good — pari is a single island, 1847 verts, 3575 tris. The z-range [10.546, 14.613] seems to be in a different scale (likely MD's cm units). Let me check the body's scale to understand the coordinate system. Let me also look at the dress.json config to model the pari config properly.

# Clothing Pipeline â€” garment mesh â†’ game-ready outfit part

**What this is:** a headless-Blender pipeline that takes a clothing mesh from any
source (Marvelous Designer export, marketplace FBX/OBJ/GLB, hand-modeled) and turns
it into outfit-part GLBs that ariki-game characters actually wear â€” fitted to the
real body, reduced to game budget, skinned to the shared 65-bone Quaternius
skeleton, and registered in the game's `OutfitCatalog`.

Built 2026-07-30 after the CC5/Reallusion clothing lane was investigated and
rejected (CC5 provably refuses clothing tools on AccuRig "Humanoid" characters â€”
verified via its Python API *and* GUI; see `ariki-game` session notes). Everything
here is Blender-only, deterministic, and agent-drivable end to end.

## Why each stage exists

A downloaded garment is useless to the game for four reasons; the pipeline is the
four fixes in order:

| Problem | Fix | Stage |
|---|---|---|
| Not shaped like our character | Shrinkwrap-fit to the real body GLB (inflated "inner shell" target guarantees clearance) | `fit` |
| Millions of tris vs ~1.5k/part budget | Split by material into parts, rebuild/decimate, bake lost detail to normal+AO maps | `reduce`, `bake` |
| No idea how to move | Copy skin weights from the character's own body (special cone-proxy recipe for skirts) | `skin` |
| Game has never heard of it | Export per-slot GLBs on the shared skeleton + register in `OutfitCatalog` | `export` + manual catalog entry |

## Design decisions (and where they came from)

Reviewed by GLM-5.2 and glm-4.6 before implementation
(`../garments/glm-advice-glm52.md`, `../garments/glm-advice.md`) plus web research
on Marvelous Designer game workflows. Key adopted corrections:

1. **Fit BEFORE decimate, bake AFTER** â€” shrinkwrapping the high-poly garment
   molds real pleat geometry; fitting a faceted low-poly loses the silhouette.
2. **Pleated skirts are not decimated** â€” a clean low-poly cylinder proxy is
   generated and shrinkwrapped to the high-poly skirt; pleats live in the baked
   normal map (at 1.5k tris geometric pleats read as noise).
3. **Skirt weights come from a "cone proxy"** â€” a leg-bridging tapered cylinder
   weighted with a Z-gradient (body weights at waist â†’ pelvis-only at hem), then
   transferred to the skirt. Kills the hard left/right-leg seam that tears skirts
   in walk cycles. Forward-compatible with skirt bones later.
4. **Clearance via inner shell** â€” garments wrap to a ~4mm inflated copy of the
   body, not the body itself: mathematical clearance, not hope.
5. **Layer stacking** â€” bow wraps to bodice, bodice wraps to body shell
   (cumulative offsets), so layered cloth keeps separation.
6. **Weight transfer uses Data Transfer 'nearest face interpolated'**, not raw
   nearest-vertex KDTree (fails on overhangs like collars/bow tails).
7. Per-part tri budgets vary (bow ~400, bodice ~1200, skirt ~2200);
   verify in the game test bed EARLY (after skin), not at the end.

Sources also agree: if a garment came from Marvelous Designer, re-exporting from
MD with lower particle density / MD's own quad remesh skips the worst reduction
pain at the source. Prefer that when the .zprj is available.

## Files

| File | What |
|---|---|
| `garment_pipeline.py` | The whole pipeline. One Blender headless script, staged; each stage checkpoints a .blend into `work/` so stages can be re-run/iterated independently. |
| `configs/<garment>.json` | Per-garment recipe: source file, islandâ†’part mapping, slots, budgets, alignment, fit, cuts. The pipeline is data-driven; new garment = new config, not new code. |
| `work/` | Intermediates (checkpoint .blends, census data, QA renders). Disposable, gitignored. |
| `README.md` | This file. |

## Stages as-built (2026-07-30, after the dress pilot)

| Stage | What it does | Hard lessons baked in |
|---|---|---|
| `census` | Import garment, drop configured junk materials, weld, split into loose **islands**, render each in a distinct color + write `work/<name>/census.json` | MD material names lie (all fabric on one material; 4M faces were topstitch threads â†’ `drop_materials`). Parts are configured as island index lists, not material names. |
| `prepare` | Import body+rig, build configured parts from islands, **bodyshell** parts cut from the body itself, sleeve pose-warp (garment-local, pre-align), anisotropic align (`scale_xy`/`scale_z` â€” heroic bodies are wide, not tall), radial `torso_boost`, post-align `cut_above_z`/`cut_outboard_x`, `prune_scraps_x` (drop disconnected leftovers by centroid) | Fitted tops on a bust bigger than the garment shred under any shrinkwrap â€” use a **bodyshell** part (body region copy + normal offset, Islander technique): perfect fit and weights by construction. Cuts must run post-align in body space. |
| `fit` | Inflated `BODY_SHELL` (+4mm) target; shrinkwrap mode **OUTSIDE** (push out penetrating verts ONLY â€” never snap the whole cloth, that shreds layered garments) | `OUTSIDE_SURFACE` destroyed multi-layer bodices; `OUTSIDE` unmasked is safe everywhere since it can't pull cloth inward. |
| `reduce` | Keep `HI_<part>` copy for baking; `weld_band` fuses stacked layers (waistband/belt sandwiches) before decimation; planar dissolve â†’ collapse to per-part budget; optional cylinder proxy for standalone skirts | Decimating coincident stacked layers = swiss cheese; protecting zones from the decimator just moves the damage elsewhere â€” **weld the sandwich first**. |
| `bake` | (optional, Cycles) normals+AO from HI onto a second UV map | |
| `skin` | Data Transfer (nearest-face-interpolated) from body; `weights: dress` adds pelvis-gradient below hip so the hem doesn't tear between legs; bodyshell parts keep inherited weights; smooth+normalize; bind to RIG | |
| `export` | One GLB per outfit slot (multi-part slots joined by selection), full 65-bone armature included, vertex hash printed for determinism | |

## Handing off downstream

Export three ways per garment, into `tools/tailor/`:

```python
export_api.ExportZPrj(".../lena_<garment>_v<N>.zprj")           # editable source of truth
op = ApiTypes.ImportExportOption(); op.bExportGarment = True; op.bExportAvatar = False
export_api.ExportFBX(".../lena_<garment>_v<N>_garment.fbx", op) # for clothing/
export_api.ExportOBJ(".../lena_<garment>_v<N>_garment.obj", op)
export_api.ExportZPac(".../lena_<garment>_v<N>.zpac")           # for outfit assembly
```

Then the garment goes through `clothing/garment_pipeline.py` (fit â†’ reduce â†’
skin â†’ export) to become a game outfit part. **Two advantages MD-authored
garments have over downloaded ones**, worth exploiting in the config:

- **They're already game budget.** These export at 1.2kâ€“3.7k verts; the
  downloaded MD dress the clothing pipeline was piloted on is 2.49 M verts /
  110 MB. The brutal `reduce` stage is mostly unnecessary â€” start with a high
  tri budget and only decimate if the test bed complains.
- **They're already fitted**, having been draped on the actual game body, so
  `align`/`fit` needs little more than the clearance shell.

Keep the `.zprj` â€” regenerating a variant beats re-authoring, and the clothing
README explicitly prefers re-exporting from MD over fighting reduction.

## Failure catalogue (don't rediscover these)

- **Shorts / trousers are unsolved.** Two-panel crotch-notch construction twists
  every time â€” fabric can't thread between Lena's touching thighs, and all seam
  parities were tried. Next approach: **4 panels arranged on the per-leg points**
  (`Leg_Front_L/R`, `Leg_Back_L/R`) so cloth starts wrapped around each thigh.
- **Upside-down panels** (y-down drafting) â€” see the y+ = UP rule.
- **Elastic-first drapes** slide off a hip; **soft-from-frame-0** drapes bunch.
- **Co-draping** two garments inverts one.
- **Retexturing after a scene merge** silently repaints the wrong garment.
- **Threaded/background socket servers inside MD never answer** â€” the bridge must
  own the main thread. Don't "fix" the frozen UI by re-threading it; that was
  tried and the design is deliberate.
- MD 2026's **AI Image Generator / EveryWear are GUI-only** â€” not scriptable.

# Garment pipeline: clothing mesh (any source) -> game-ready outfit-part GLBs
# on the shared 65-bone Quaternius skeleton. See README.md for design rationale
# (GLM-reviewed: fit-before-decimate, skirt proxy + cone weights, inner-shell
# clearance, layer stacking).
#
# Staged; every stage loads the previous checkpoint .blend from work/ and saves
# its own, so any stage can be re-run alone while iterating:
#
#   blender --background --python garment_pipeline.py -- \
#       --config configs/dress.json --stage prepare|fit|reduce|bake|skin|export
#
# Naming inside the .blend (stable contract between stages):
#   GARM_<Part>   garment part mesh (high-poly until `reduce`, low-poly after)
#   HI_<Part>     hidden high-poly copy kept for baking (created by `reduce`)
#   BODY          the target body mesh (from the game GLB, with vertex groups)
#   BODY_SHELL    inflated clearance copy of BODY (fit target)
#   RIG           the Quaternius armature imported with BODY
#   CONE_<Part>   skirt weight-transfer proxy (created by `skin`, kept for QA)

# Clothing Pipeline â€” garment mesh â†’ game-ready outfit part

**What this is:** a headless-Blender pipeline that takes a clothing mesh from any
source (Marvelous Designer export, marketplace FBX/OBJ/GLB, hand-modeled) and turns
it into outfit-part GLBs that ariki-game characters actually wear â€” fitted to the
real body, reduced to game budget, skinned to the shared 65-bone Quaternius
skeleton, and registered in the game's `OutfitCatalog`.

Built 2026-07-30 after the CC5/Reallusion clothing lane was investigated and
rejected (CC5 provably refuses clothing tools on AccuRig "Humanoid" characters â€”
verified via its Python API *and* GUI; see `ariki-game` session notes). Everything
here is Blender-only, deterministic, and agent-drivable end to end.

## Why each stage exists

A downloaded garment is useless to the game for four reasons; the pipeline is the
four fixes in order:

| Problem | Fix | Stage |
|---|---|---|
| Not shaped like our character | Shrinkwrap-fit to the real body GLB (inflated "inner shell" target guarantees clearance) | `fit` |
| Millions of tris vs ~1.5k/part budget | Split by material into parts, rebuild/decimate, bake lost detail to normal+AO maps | `reduce`, `bake` |
| No idea how to move | Copy skin weights from the character's own body (special cone-proxy recipe for skirts) | `skin` |
| Game has never heard of it | Export per-slot GLBs on the shared skeleton + register in `OutfitCatalog` | `export` + manual catalog entry |

## Design decisions (and where they came from)

Reviewed by GLM-5.2 and glm-4.6 before implementation
(`../garments/glm-advice-glm52.md`, `../garments/glm-advice.md`) plus web research
on Marvelous Designer game workflows. Key adopted corrections:

1. **Fit BEFORE decimate, bake AFTER** â€” shrinkwrapping the high-poly garment
   molds real pleat geometry; fitting a faceted low-poly loses the silhouette.
2. **Pleated skirts are not decimated** â€” a clean low-poly cylinder proxy is
   generated and shrinkwrapped to the high-poly skirt; pleats live in the baked
   normal map (at 1.5k tris geometric pleats read as noise).
3. **Skirt weights come from a "cone proxy"** â€” a leg-bridging tapered cylinder
   weighted with a Z-gradient (body weights at waist â†’ pelvis-only at hem), then
   transferred to the skirt. Kills the hard left/right-leg seam that tears skirts
   in walk cycles. Forward-compatible with skirt bones later.
4. **Clearance via inner shell** â€” garments wrap to a ~4mm inflated copy of the
   body, not the body itself: mathematical clearance, not hope.
5. **Layer stacking** â€” bow wraps to bodice, bodice wraps to body shell
   (cumulative offsets), so layered cloth keeps separation.
6. **Weight transfer uses Data Transfer 'nearest face interpolated'**, not raw
   nearest-vertex KDTree (fails on overhangs like collars/bow tails).
7. Per-part tri budgets vary (bow ~400, bodice ~1200, skirt ~2200);
   verify in the game test bed EARLY (after skin), not at the end.

Sources also agree: if a garment came from Marvelous Designer, re-exporting from
MD with lower particle density / MD's own quad remesh skips the worst reduction
pain at the source. Prefer that when the .zprj is available.

## Files

| File | What |
|---|---|
| `garment_pipeline.py` | The whole pipeline. One Blender headless script, staged; each stage checkpoints a .blend into `work/` so stages can be re-run/iterated independently. |
| `configs/<garment>.json` | Per-garment recipe: source file, islandâ†’part mapping, slots, budgets, alignment, fit, cuts. The pipeline is data-driven; new garment = new config, not new code. |
| `work/` | Intermediates (checkpoint .blends, census data, QA renders). Disposable, gitignored. |
| `README.md` | This file. |

## Stages as-built (2026-07-30, after the dress pilot)

| Stage | What it does | Hard lessons baked in |
|---|---|---|
| `census` | Import garment, drop configured junk materials, weld, split into loose **islands**, render each in a distinct color + write `work/<name>/census.json` | MD material names lie (all fabric on one material; 4M faces were topstitch threads â†’ `drop_materials`). Parts are configured as island index lists, not material names. |
| `prepare` | Import body+rig, build configured parts from islands, **bodyshell** parts cut from the body itself, sleeve pose-warp (garment-local, pre-align), anisotropic align (`scale_xy`/`scale_z` â€” heroic bodies are wide, not tall), radial `torso_boost`, post-align `cut_above_z`/`cut_outboard_x`, `prune_scraps_x` (drop disconnected leftovers by centroid) | Fitted tops on a bust bigger than the garment shred under any shrinkwrap â€” use a **bodyshell** part (body region copy + normal offset, Islander technique): perfect fit and weights by construction. Cuts must run post-align in body space. |
| `fit` | Inflated `BODY_SHELL` (+4mm) target; shrinkwrap mode **OUTSIDE** (push out penetrating verts ONLY â€” never snap the whole cloth, that shreds layered garments) | `OUTSIDE_SURFACE` destroyed multi-layer bodices; `OUTSIDE` unmasked is safe everywhere since it can't pull cloth inward. |
| `reduce` | Keep `HI_<part>` copy for baking; `weld_band` fuses stacked layers (waistband/belt sandwiches) before decimation; planar dissolve â†’ collapse to per-part budget; optional cylinder proxy for standalone skirts | Decimating coincident stacked layers = swiss cheese; protecting zones from the decimator just moves the damage elsewhere â€” **weld the sandwich first**. |
| `bake` | (optional, Cycles) normals+AO from HI onto a second UV map | |
| `skin` | Data Transfer (nearest-face-interpolated) from body; `weights: dress` adds pelvis-gradient below hip so the hem doesn't tear between legs; bodyshell parts keep inherited weights; smooth+normalize; bind to RIG | |
| `export` | One GLB per outfit slot (multi-part slots joined by selection), full 65-bone armature included, vertex hash printed for determinism | |

## Current pilot

`configs/dress.json` â†’ `../garments/thin-unweld.fbx`: an MD dress ensemble
(2.49M verts, 12 materials). v1 scope: bodice + belt/bow (Body slot) + pleated
skirt (Legs slot). The sleeved jacket (`cape*` materials) is deferred â€” sleeves
need a pose-warp to T-pose (GLM advice Â§4 has the recipe) and is round two.
Unknown `Material*` slots are excluded pending the per-material stats `prepare`
prints; reassign them in the config if they turn out to be buttons/trim.

## Known limitations (v1)

- Skirt will still favor standing/dance poses; deep leg swings compress the hem
  (no skirt bones yet â€” the Z-gradient weights are ready for them later).
- Flat MD colors until someone supplies textures (bake stage produces normal+AO,
  not albedo).
- Body stays under garments (no hide-mask system in game yet) â€” clearance is the
  only poke-through defense; report tunnel-through in the test bed per animation.

# Marvelous Designer â€” agentic garment authoring

The **upstream half** of the clothing lane: reference image (or a description) â†’
sewn, draped, textured garment mesh fitted to the game body. The downstream half
(garment mesh â†’ game-ready skinned GLB) is `clothing/` â€” see
`.agents/wiki/architecture/clothing-lane.md` for how they meet.

Everything here was learned by doing it on 2026-07-30 (tee, skirt, kapa haka
pari + piupiu). The API facts are **verified against MD 2026 Personal**, not
docs â€” Reallusion/CLO's published API docs are thin and several signatures in
them are wrong.

## The 60-second model

- MD is driven through **`tools/md_bridge.py`** â†’ a socket plugin running inside
  MD (`tools/md_bridge/TinqsMDBridge.py`). Full protocol: `docs/md-bridge.md`.
- A garment = **flat 2D panels** (`CreatePatternWithPoints`) + **seams**
  (`AddSeamlinePairGroup`) + **arrangement points** on the avatar
  (`SetArrangement`), then **simulate** (`utility_api.Simulate(frames)`) to drape
  cloth onto the body.
- You see results by rendering the viewport to PNG (`ExportSnapshot3D`) and
  reading the image back. **This vision loop is the whole method** â€” draft,
  drape, look, measure, adjust, repeat.
- Garment identity for traditional wear is mostly **textiles, not tailoring**.
  Kapa haka / Mexica / Pacific garments are rectangles + blocks; the design lives
  in generated texture maps. Model the shape simply, spend effort on the pattern.

## Session protocol (read first â€” MD's UI freezes)

MD's embedded Python **does not run background threads**, so the bridge owns the
main thread while it serves. Consequences:

1. **A human must click** Plugin â†’ TinqsMDBridge to start a session. You cannot
   start one yourself. Ask, then wait.
2. **MD's UI is frozen** for the whole session ("Not Responding" is normal).
3. End with `python tools/md_bridge.py --stop` â€” works from the terminal even
   though the UI is dead. Idle timeout is 4 h (was 300 s; raised so one click
   lasts a work session).
4. **Pause the session whenever Jeremy wants to look at the model.** He inspects
   in MD's viewport; he can't while you hold the thread. Default to stopping when
   you hand back a result, unless he said to stay in.

```bash
python tools/md_bridge.py --ping                       # verify + see mode/api modules
python tools/md_bridge.py --exec "result = pattern_api.GetPatternCount()"
python tools/md_bridge.py --file tools/tailor/md_pari.py --timeout 500
python tools/md_bridge.py --stop                       # give the UI back
```

Long `Simulate()` calls need a raised client `--timeout` (~1 min per 300 frames).
The exec namespace persists **within** a session, not across; MD api modules
(`pattern_api`, `import_api`, `export_api`, `fabric_api`, `utility_api`,
`ApiTypes`) plus a `BRIDGE` info dict are pre-seeded.

**Introspect, don't trust docs.** Full surface dump lives at
`tools/md_bridge/api_surface.json` (688 functions) and harvested docstrings at
`tools/md_bridge/api_docs.json`. Overloaded pybind11 functions break
`inspect.signature()` â€” read `__doc__` instead.

## API facts that cost hours to find

| Fact | Consequence |
|---|---|
| **2D pattern y+ maps to UP in 3D** | Panels drafted y-down drape **upside-down over the head** and tangle. Symptom looks like a seam bug; it isn't. Hem at y=0, neckline at high y. |
| Units are **mm**; gravity âˆ’9800 | A "500" square is 50 cm. |
| Blender-exported FBX avatars import **10Ã— small** | Import with `op.scale = 10.0`. |
| `ImportAvatar()` is **.avt only** â€” returns `False` on FBX | Use **`import_api.ImportFBX(path, op)`** for the game body. |
| `op.bAddArrangementPoints = True` | Auto-generates ~98 named arrangement points on a custom avatar. Without it you have nowhere to hang cloth. |
| `SetArrangement()` only *assigns*; **`utility_api.ResetClothArrangement()` applies** it | Skipping the apply = nothing moves. (`ReDrape3DArrangement` only materializes not-yet-draped cloth.) |
| Arrangement **indices regenerate** per avatar import | Always look up by name from `GetArrangementList()`; never hardcode an index. Offsets aren't stable either â€” verify with a 0-frame snapshot. |
| Avatar getters live in **`export_api`** (`GetAvatarCount`, `GetAvatarNameList`) | Not `utility_api`, where you'd look. |
| `utility_api.NewProject()` **deletes the avatar** | Re-import after. |
| `SetBaseTextureMapImageGivenFilePath(path, fabricIdx)` â€” **path is arg0** | Reversed args throw a TypeError that reads like a missing overload. |
| **PNG DPI sets a texture's physical size in MD** | 1024 px at 54.2 dpi = 480 mm of cloth. Control tiling by setting dpi in PIL, not by scaling the image. |
| `fabric_api.AddFabric()` needs a **`.zfab` file path** | A name string silently fails. Stock presets: `C:\Users\Public\Documents\MarvelousDesigner\New Assets\Fabric\`. |
| Fabric **index 0 is the shared default** | Coloring it dyes every garment in the scene. Always `AddFabric` a new one. |
| `AssignFabricToPattern()` returns False for every arg order tried | Use **`pattern_api.SetPatternPieceFabricIndex(pattern, fabric)`**. |
| `SetViewPoint()` does nothing; **`SetCamViewPoint(2)` = front view** | Call before every QC snapshot so shots are comparable. |
| `GetClothPositions()` is an out-param that stays empty from Python | No mesh introspection â€” measure from rendered images instead (see QC). |
| No `SaveProjectFile`; no glTF export; no EveryWear in the API | Save = `export_api.ExportZPrj`. Exits: `ExportFBX` /

## Handing off downstream

Export three ways per garment, into `tools/tailor/`:

```python
export_api.ExportZPrj(".../lena_<garment>_v<N>.zprj")           # editable source of truth
op = ApiTypes.ImportExportOption(); op.bExportGarment = True; op.bExportAvatar = False
export_api.ExportFBX(".../lena_<garment>_v<N>_garment.fbx", op) # for clothing/
export_api.ExportOBJ(".../lena_<garment>_v<N>_garment.obj", op)
export_api.ExportZPac(".../lena_<garment>_v<N>.zpac")           # for outfit assembly
```

Then the garment goes through `clothing/garment_pipeline.py` (fit â†’ reduce â†’
skin â†’ export) to become a game outfit part. **Two advantages MD-authored
garments have over downloaded ones**, worth exploiting in the config:

- **They're already game budget.** These export at 1.2kâ€“3.7k verts; the
  downloaded MD dress the clothing pipeline was piloted on is 2.49 M verts /
  110 MB. The brutal `reduce` stage is mostly unnecessary â€” start with a high
  tri budget and only decimate if the test bed complains.
- **They're already fitted**, having been draped on the actual game body, so
  `align`/`fit` needs little more than the clearance shell.

Keep the `.zprj` â€” regenerating a variant beats re-authoring, and the clothing
README explicitly prefers re-exporting from MD over fighting reduction.

## Failure catalogue (don't rediscover these)

- **Shorts / trousers are unsolved.** Two-panel crotch-notch construction twists
  every time â€” fabric can't thread between Lena's touching thighs, and all seam
  parities were tried. Next approach: **4 panels arranged on the per-leg points**
  (`Leg_Front_L/R`, `Leg_Back_L/R`) so cloth starts wrapped around each thigh.
- **Upside-down panels** (y-down drafting) â€” see the y+ = UP rule.
- **Elastic-first drapes** slide off a hip; **soft-from-frame-0** drapes bunch.
- **Co-draping** two garments inverts one.
- **Retexturing after a scene merge** silently repaints the wrong garment.
- **Threaded/background socket servers inside MD never answer** â€” the bridge must
  own the main thread. Don't "fix" the frozen UI by re-threading it; that was
  tried and the design is deliberate.
- MD 2026's **AI Image Generator / EveryWear are GUI-only** â€” not scriptable.

Now I understand the align logic. The key line is:
```python
dz = (b_top - gz1) + a.get("z_nudge", 0.0)
```
where `gz1` is the garment's top Z after scaling. For these garments, I need `z_nudge` to cancel the auto-align so the net placement is `[z0/10, z1/10]`.

Let me now look at the import_garment_islands function and the rest of the pipeline (fit, reduce, skin, export).

# Clothing Pipeline â€” garment mesh â†’ game-ready outfit part

**What this is:** a headless-Blender pipeline that takes a clothing mesh from any
source (Marvelous Designer export, marketplace FBX/OBJ/GLB, hand-modeled) and turns
it into outfit-part GLBs that ariki-game characters actually wear â€” fitted to the
real body, reduced to game budget, skinned to the shared 65-bone Quaternius
skeleton, and registered in the game's `OutfitCatalog`.

Built 2026-07-30 after the CC5/Reallusion clothing lane was investigated and
rejected (CC5 provably refuses clothing tools on AccuRig "Humanoid" characters â€”
verified via its Python API *and* GUI; see `ariki-game` session notes). Everything
here is Blender-only, deterministic, and agent-drivable end to end.

## Why each stage exists

A downloaded garment is useless to the game for four reasons; the pipeline is the
four fixes in order:

| Problem | Fix | Stage |
|---|---|---|
| Not shaped like our character | Shrinkwrap-fit to the real body GLB (inflated "inner shell" target guarantees clearance) | `fit` |
| Millions of tris vs ~1.5k/part budget | Split by material into parts, rebuild/decimate, bake lost detail to normal+AO maps | `reduce`, `bake` |
| No idea how to move | Copy skin weights from the character's own body (special cone-proxy recipe for skirts) | `skin` |
| Game has never heard of it | Export per-slot GLBs on the shared skeleton + register in `OutfitCatalog` | `export` + manual catalog entry |

## Design decisions (and where they came from)

Reviewed by GLM-5.2 and glm-4.6 before implementation
(`../garments/glm-advice-glm52.md`, `../garments/glm-advice.md`) plus web research
on Marvelous Designer game workflows. Key adopted corrections:

1. **Fit BEFORE decimate, bake AFTER** â€” shrinkwrapping the high-poly garment
   molds real pleat geometry; fitting a faceted low-poly loses the silhouette.
2. **Pleated skirts are not decimated** â€” a clean low-poly cylinder proxy is
   generated and shrinkwrapped to the high-poly skirt; pleats live in the baked
   normal map (at 1.5k tris geometric pleats read as noise).
3. **Skirt weights come from a "cone proxy"** â€” a leg-bridging tapered cylinder
   weighted with a Z-gradient (body weights at waist â†’ pelvis-only at hem), then
   transferred to the skirt. Kills the hard left/right-leg seam that tears skirts
   in walk cycles. Forward-compatible with skirt bones later.
4. **Clearance via inner shell** â€” garments wrap to a ~4mm inflated copy of the
   body, not the body itself: mathematical clearance, not hope.
5. **Layer stacking** â€” bow wraps to bodice, bodice wraps to body shell
   (cumulative offsets), so layered cloth keeps separation.
6. **Weight transfer uses Data Transfer 'nearest face interpolated'**, not raw
   nearest-vertex KDTree (fails on overhangs like collars/bow tails).
7. Per-part tri budgets vary (bow ~400, bodice ~1200, skirt ~2200);
   verify in the game test bed EARLY (after skin), not at the end.

Sources also agree: if a garment came from Marvelous Designer, re-exporting from
MD with lower particle density / MD's own quad remesh skips the worst reduction
pain at the source. Prefer that when the .zprj is available.

## Files

| File | What |
|---|---|
| `garment_pipeline.py` | The whole pipeline. One Blender headless script, staged; each stage checkpoints a .blend into `work/` so stages can be re-run/iterated independently. |
| `configs/<garment>.json` | Per-garment recipe: source file, islandâ†’part mapping, slots, budgets, alignment, fit, cuts. The pipeline is data-driven; new garment = new config, not new code. |
| `work/` | Intermediates (checkpoint .blends, census data, QA renders). Disposable, gitignored. |
| `README.md` | This file. |

## Stages as-built (2026-07-30, after the dress pilot)

| Stage | What it does | Hard lessons baked in |
|---|---|---|
| `census` | Import garment, drop configured junk materials, weld, split into loose **islands**, render each in a distinct color + write `work/<name>/census.json` | MD material names lie (all fabric on one material; 4M faces were topstitch threads â†’ `drop_materials`). Parts are configured as island index lists, not material names. |
| `prepare` | Import body+rig, build configured parts from islands, **bodyshell** parts cut from the body itself, sleeve pose-warp (garment-local, pre-align), anisotropic align (`scale_xy`/`scale_z` â€” heroic bodies are wide, not tall), radial `torso_boost`, post-align `cut_above_z`/`cut_outboard_x`, `prune_scraps_x` (drop disconnected leftovers by centroid) | Fitted tops on a bust bigger than the garment shred under any shrinkwrap â€” use a **bodyshell** part (body region copy + normal offset, Islander technique): perfect fit and weights by construction. Cuts must run post-align in body space. |
| `fit` | Inflated `BODY_SHELL` (+4mm) target; shrinkwrap mode **OUTSIDE** (push out penetrating verts ONLY â€” never snap the whole cloth, that shreds layered garments) | `OUTSIDE_SURFACE` destroyed multi-layer bodices; `OUTSIDE` unmasked is safe everywhere since it can't pull cloth inward. |
| `reduce` | Keep `HI_<part>` copy for baking; `weld_band` fuses stacked layers (waistband/belt sandwiches) before decimation; planar dissolve â†’ collapse to per-part budget; optional cylinder proxy for standalone skirts | Decimating coincident stacked layers = swiss cheese; protecting zones from the decimator just moves the damage elsewhere â€” **weld the sandwich first**. |
| `bake` | (optional, Cycles) normals+AO from HI onto a second UV map | |
| `skin` | Data Transfer (nearest-face-interpolated) from body; `weights: dress` adds pelvis-gradient below hip so the hem doesn't tear between legs; bodyshell parts keep inherited weights; smooth+normalize; bind to RIG | |
| `export` | One GLB per outfit slot (multi-part slots joined by selection), full 65-bone armature included, vertex hash printed for determinism | |

## Current pilot

`configs/dress.json` â†’ `../garments/thin-unweld.fbx`: an MD dress ensemble
(2.49M verts, 12 materials). v1 scope: bodice + belt/bow (Body slot) + pleated
skirt (Legs slot). The sleeved jacket (`cape*` materials) is deferred â€” sleeves
need a pose-warp to T-pose (GLM advice Â§4 has the recipe) and is round two.
Unknown `Material*` slots are excluded pending the per-material stats `prepare`
prints; reassign them in the config if they turn out to be buttons/trim.

## Known limitations (v1)

- Skirt will still favor standing/dance poses; deep leg swings compress the hem
  (no skirt bones yet â€” the Z-gradient weights are ready for them later).
- Flat MD colors until someone supplies textures (bake stage produces normal+AO,
  not albedo).
- Body stays under garments (no hide-mask system in game yet) â€” clearance is the
  only poke-through defense; report tunnel-through in the test bed per animation.

## Handing off downstream

Export three ways per garment, into `tools/tailor/`:

```python
export_api.ExportZPrj(".../lena_<garment>_v<N>.zprj")           # editable source of truth
op = ApiTypes.ImportExportOption(); op.bExportGarment = True; op.bExportAvatar = False
export_api.ExportFBX(".../lena_<garment>_v<N>_garment.fbx", op) # for clothing/
export_api.ExportOBJ(".../lena_<garment>_v<N>_garment.obj", op)
export_api.ExportZPac(".../lena_<garment>_v<N>.zpac")           # for outfit assembly
```

Then the garment goes through `clothing/garment_pipeline.py` (fit â†’ reduce â†’
skin â†’ export) to become a game outfit part. **Two advantages MD-authored
garments have over downloaded ones**, worth exploiting in the config:

- **They're already game budget.** These export at 1.2kâ€“3.7k verts; the
  downloaded MD dress the clothing pipeline was piloted on is 2.49 M verts /
  110 MB. The brutal `reduce` stage is mostly unnecessary â€” start with a high
  tri budget and only decimate if the test bed complains.
- **They're already fitted**, having been draped on the actual game body, so
  `align`/`fit` needs little more than the clearance shell.

Keep the `.zprj` â€” regenerating a variant beats re-authoring, and the clothing
README explicitly prefers re-exporting from MD over fighting reduction.

## Failure catalogue (don't rediscover these)

- **Shorts / trousers are unsolved.** Two-panel crotch-notch construction twists
  every time â€” fabric can't thread between Lena's touching thighs, and all seam
  parities were tried. Next approach: **4 panels arranged on the per-leg points**
  (`Leg_Front_L/R`, `Leg_Back_L/R`) so cloth starts wrapped around each thigh.
- **Upside-down panels** (y-down drafting) â€” see the y+ = UP rule.
- **Elastic-first drapes** slide off a hip; **soft-from-frame-0** drapes bunch.
- **Co-draping** two garments inverts one.
- **Retexturing after a scene merge** silently repaints the wrong garment.
- **Threaded/background socket servers inside MD never answer** â€” the bridge must
  own the main thread. Don't "fix" the frozen UI by re-threading it; that was
  tried and the design is deliberate.
- MD 2026's **AI Image Generator / EveryWear are GUI-only** â€” not scriptable.

Good — configs already exist. The census data confirms:
- pari: z-range [10.546, 14.613] → target [1.055, 1.461]
- piupiu: z-range [5.184, 11.126] → target [0.518, 1.113]

The configs use `scale_xy: 0.1, scale_z: 0.1` which is correct. But the issue is the `top_bone` auto-align. Let me check the dress.json config for reference, then look at the pipeline's prepare stage to understand the auto-align logic.

--- step 45 (103 min left) ---
Now I understand the auto-align logic. After scaling, it computes:
- `gz1` = garment's top z after scaling
- `b_top` = bone head z of `top_bone`
- `dz = (b_top - gz1) + z_nudge`

For the pari with scale 0.1:
- After scaling, garment top = 14.613 * 0.1 = 1.4613
- `neck_01` head z = 1.413
- `dz = (1.413 - 1.4613) + z_nudge = -0.0483 + z_nudge`

But the target top is 1.461 (14.613/10). So we need `dz = 0` for the garment to stay at 1.4613. That means `z_nudge = 0.0483` to cancel the auto-align.

Let me verify by measuring the current prepare checkpoint.

--- step 46 (103 min left) ---
COMMAND: "/c/Program Files/Blender Foundation/Blender 5.1/blender.exe" --background clothing/work/pari/10_prepare.blend --python-expr "import bpy; o=[x for x in bpy.data.objects if x.name.startswith('GARM_')][0]; zs=[(o.matrix_world@v.co).z for v in o.data.vertices]; print('ZRANGE', min(zs), max(zs))" 2>/dev/null | grep ZRANGE
[output]
exit=0
ZRANGE 0.957629919052124 1.3643112182617188

--- step 47 (103 min left) ---
The current pari prepare has z-range [0.958, 1.364] but the target is [1.055, 1.461]. The top is off by 1.461 - 1.364 = 0.097, and the bottom is off by 1.055 - 0.958 = 0.097. So it's shifted 0.097 too low — exactly the problem described.

I need `z_nudge = +0.0483` to cancel the auto-align. Let me compute precisely: target top = 14.613/10 = 1.4613, current scaled top before align = 1.4613, b_top (neck_01) = 1.413, so dz = (1.413 - 1.4613) + z_nudge. For dz=0, z_nudge = 0.0483.

Let me update the pari config.

--- step 48 (102 min left) ---
COMMAND: python -c "
import json
with open('clothing/configs/pari.json') as f: c=json.load(f)
c['align']['z_nudge'] = 0.0483
with open('clothing/configs/pari.json','w') as f: json.dump(c,f,indent=2)
print('updated z_nudge to', c['align']['z_nudge'])

[output]

--- step 50 (102 min left) ---
Now let me re-run the prepare stage for pari and measure the result.

The config has `top_bone: "spine_01"` which will auto-align. The raw z-range is [5.184, 11.126], so target world range is [0.518, 1.113]. The top should be at 1.113. Let me run prepare and see what we get, then adjust z_nudge.

The piupiu config worked well. The pari config has `z_nudge: 0.0483` which was from the previous (wrong) run. I need to redo the pari from scratch. Let me first run the census stage to get fresh data, then fix the config. But first, let me check if there's an existing work directory with old census data.

The log shows `dz=-0.0004` which means the auto-align computed a very small dz. Let me measure the actual Z bounds of the garment in the checkpoint.

Excellent! The measured Z range is [1.054, 1.461], which matches the target [1.055, 1.461] almost perfectly (within 0.001m). The current config with `z_nudge: 0.0483` is actually producing correct placement now! The `dz=-0.0004` from auto-align plus the `z_nudge=0.0483` results in a net placement that's correct.

The gltf has 1523 verts (accessor 0), 8775 indices (2925 tris), and 65 bones (accessor 6 = 65 MAT4). The earlier import just didn't work correctly. The pari is done correctly. Now let me move on to the piupiu (Legs). First, let me check if there's already a config for it:

67 nodes = 65 bones + 2 (root + mesh node). 2599 verts. Now let me check the pari (Body) status. First, let me check what's in the export folder:

Both files exist. The task says the pari (Body) is WRONG and must be redone. Let me delete it and rebuild. First, let me check the pari config and census:

The pari prepare checkpoint already has the correct z-range: [1.054, 1.461] vs target [1.055, 1.461]. That's within 0.02m. The config's z_nudge of 0.0483 is already correct. Now let me run the remaining stages. First fit:
