# lena_base_v01 — SHIPPED 2026-08-10

**Frozen.** Nothing in this folder is ever edited or re-exported (REGISTRY rule 2).
Any change at all becomes `lena_base_v02`.

The game's female base body. Nude sculpt (no bra, no briefs, no nipples, featureless
crotch), athletic definition in the normal map, 65-bone Quaternius skeleton.

## Contents

| file | what |
|---|---|
| `lena_base_accurig_glb_v01.glb` | the body as it left this repo — mesh + atlas + AccuRig skeleton, 31,111 v / 101 joints. `doubleSided=true` |
| `rig/lena_base_accurig_fbx_v01/` | **irreplaceable.** Output of a manual AccuRig 1.10.1822.1 session — no script regenerates this. Settings JSON kept alongside as provenance |
| `rig/lena_base_tpose_fbx_v01.fbx` | the carrier fed *into* that AccuRig session. Regenerable (`45_accurig_export.py`) but kept so the rig is reproducible end to end |
| `preview/` | renders of the shipped body |

## Where it went

Converted to the 65-bone contract by `ariki-game/tools/make_lena_nude_quatskin_accurig.py`
and imported as:

- `Ariki_Female_QuatSkin_Nude.glb` — sha256 `75a51668fe6f084b60995fd257afd2ee8e4e6317d1676ff793675ca018f237b0`
- `Ariki_Female_QuatSkin.glb` — same body, swapped in on 2026-08-10. The body it
  replaced is kept as `Ariki_Female_QuatSkin_PRESWAP_2026-08-10.glb.bak`.

Textures ship loose as `Ariki_Female_QuatSkin_Nude_athletic_v04_{base,normal,rm}.jpg`.

## Two facts that bite

- **`doubleSided=true` is load-bearing.** Patches of the mesh are wound inward; a
  single-sided material culls them into grey holes across her face and underbust.
- **Two corrections live in the graft**, both solved by least-squares fit rather than
  hardcoded: the T-pose carrier was exported at 1.700 m (scale 0.576058) and AccuRig
  shifted the body ~11.77 mm. Same family as the July lane's 4 cm offset trap.

## Rebuilding / continuing

Recipes and masters are in `characters/work/lena/`. Start from
`masters/athletic_v04.blend` (the game-res head, 31,111 v) or `masters/34_v04.blend`
(the full-res sculpt head, 860,389 v). Full stage-by-stage history including the dead
ends is in `work/lena/README_lane_history.md`.
