feat: clothing lane, character sources, and DCC bridges
Bulk import of the working lanes that were living untracked on the PC. Content: - characters/ Lena/male body lanes, bakes, texture work, run logs - clothing/ garment pipeline, configs, gates, contract docs - garments/ MD-authored garment sources (.zprj/.zpac) - UAL-Lib/ Universal Animation Library 2 source (.blend/.fbx/.glb) - tools/ blender_bridge, iclone_bridge, md_bridge, tailor, glm_agent - docs/, plans/, dev/, .agents/plans/ Repo hygiene: - .gitattributes: LFS now covers .blend, .zprj, .zpac, .obj, .npy and the Reallusion .iAvatar/.ccAvatar/.ccRestore containers. Without this the ~3.8 GB in this commit would land as raw blobs. .png/.jpg are left out on purpose — ~250 are already tracked raw and converting them would rewrite every one without shrinking history. - .gitignore: exclude /accurig/ (~1 GB AccuRig program files, redistributable from Reallusion, nothing authored here) and /dev/null/ (git-lfs hook copies dropped by a `>/dev/null` redirect on Windows).

# Rig-graft lane — AccuRig skeleton onto pristine Tripo GLBs (PLAN, not executed)
|
||||
|
||||
**Repo home:** this plan and its tools moved from ariki-game into the animation repo
|
||||
2026-08-06 — the lane authors characters, so `characters/REGISTRY.md` governs it (see
|
||||
`.agents/wiki/ARCHITECTURE.md` "Which repo does a non-gameplay tool belong to"). Paths
|
||||
below are animation-repo-relative unless prefixed `ariki-game/`.
|
||||
|
||||
**Status 2026-08-04: PLAN ONLY. Jeremy has explicitly held execution — no model
|
||||
files are to be created or modified until the naming convention is decided.**
|
||||
|
||||
## Goal
|
||||
|
||||
Rig Ozlem's two unrigged Tripo bodies without the FBX→GLB quality loss the male
|
||||
lane hit in July (mangled textures, bad hand skinning). The move: FBX is only a
|
||||
**disposable rig carrier** through AccuRig; the **GLB is the sole source of truth**
|
||||
for mesh + materials and only ever *gains* bones and weights.
|
||||
|
||||
## Source files (curated 2026-08-04)
|
||||
|
||||
Byte-identical copies live in both repos: `characters/originals/` here (checksummed in
|
||||
`characters/REGISTRY.md`) and `ariki-game/assets/models/characters/race-sources/`. Read
|
||||
from this repo's copies.
|
||||
|
||||
| file | verts | tris | height | feet @ Z0 | axis | textures |
|
||||
|---|---|---|---|---|---|---|
|
||||
| `female_lena_tripo.glb` | 974,478 | 1,907,931 | 0.979 m | yes (0.0) | upright, rot 0, scale 1 | 3 packed 4K (basecolor/normal/rm) |
|
||||
| `female_lena_tripo.fbx` | 953,968 | 1,907,931 | 0.979 m | — | upright | 5 external JPEGs (.fbm removed; git-recoverable) |
|
||||
| `male_base_bald_tripo_v1.glb` | 969,881 | 1,901,449 | 0.980 m | yes (0.0) | upright, rot 0, scale 1 | 3 packed 4K, clean |
|
||||
| `male_base_bald_tripo_v1.fbx` | 950,729 | 1,901,449 | 0.980 m | — | **lying down (bad axis)** | 6 packed, all mislabeled "Diffuse Texture.NNN", duplicated basecolor |
|
||||
|
||||
Census facts that shape the plan:
|
||||
|
||||
- **No bones anywhere** — all four files are truly unrigged, so no rig standard is
|
||||
imposed by the sources. The 65-bone Quaternius game standard is unaffected.
|
||||
- **Identical surfaces per pair** (tri counts match exactly); vertex counts differ
|
||||
~2% from format-specific UV-seam splitting → index-exact weight copy is off the
|
||||
table, nearest-surface transfer is the mechanism (surfaces coincide, so it is
|
||||
near-exact everywhere except close-packed fingers — see step 4).
|
||||
- The male FBX's axis + texture mangling is the July failure mode reproduced in
|
||||
data — never source visual data from FBX.
|
||||
|
||||
## Decisions (Jeremy, 2026-08-04)
|
||||
|
||||
1. **NO scaling to standard height.** Bodies stay at Tripo's native ~0.98 m.
|
||||
(Any scale handling happens later, downstream, not in this lane.)
|
||||
2. **Axis check + ground the feet** — wanted, and the probe shows both GLBs
|
||||
already pass (rot 0 / scale 1 / min-Z exactly 0.0). These become verify-only
|
||||
gates, mutating nothing unless a future source fails them.
|
||||
3. **HOLD before decimation** until the naming convention for derived files is
|
||||
agreed. Nothing below the line runs until then.
|
||||
|
||||
## The lane (each step gated on the one before)
|
||||
|
||||
1. **Verify** (read-only, DONE for the two current GLBs): upright axis, unit
|
||||
scale, feet at Z=0, centered X, packed textures present.
|
||||
2. **Rig bait** *(HELD — naming)*: from the GLB, decimate a disposable copy and
|
||||
export FBX for AccuRig. **Confirmed 2026-08-04: AccuRig refuses the raw
|
||||
1.9 M-tri FBX outright** (Jeremy tried; July hit the same wall). Use the
|
||||
`ariki-game/tools/male_mesh_decimate.py` precedent: region budgets body 24k / head 14k /
|
||||
**hands 10k as their own protected region** (global-ratio decimation webs the
|
||||
fingers — half of the historic hand-mangling happened here, pre-AccuRig).
|
||||
Apply the July male-lane traps: Dummy-export quirk, the 4 cm offset.
|
||||
No scale change on the GLB — but if AccuRig misplaces joints on a 0.98 m
|
||||
body, scale the DISPOSABLE BAIT up 2× and scale the returned skeleton back
|
||||
down in the graft; the GLB never changes size.
|
||||
3. **AccuRig** (manual, Jeremy/Ozlem): rig the bait FBX. Export rigged FBX.
|
||||
4. **Graft** (headless Blender): import rigged bait FBX + pristine GLB; snap rest
|
||||
poses; transfer skeleton + skin weights decimated→full-res by nearest-surface
|
||||
with tight max-distance; **hands get special handling** (per-finger masked
|
||||
transfer or reduced distance + limit-totals + normalize) — this is where the
|
||||
old hand mangling gets fixed. Export GLB: original mesh + original packed
|
||||
textures + new rig. FBX artifacts are discarded.
|
||||
5. **QC**: pose sweep incl. finger curls; then (if/when destined for game) the
|
||||
existing AccuRig→Quaternius conversion (`ariki-game/tools/make_male_ib_quatskin_accurig.py`
|
||||
lineage) picks it up.
|
||||
|
||||
## Naming + step 2 status (RESOLVED 2026-08-04, later same day)
|
||||
|
||||
Jeremy raised the hands budget and released the bait step. Built with
|
||||
`tools/rigbait_decimate.py` (parameterized successor to male_mesh_decimate.py —
|
||||
no scale/recenter, bbox-relative region cuts, budgets body 24k / head 14k /
|
||||
**hands 40k**):
|
||||
|
||||
- `characters/rig-work/lena_tripo_rigbait.fbx` — 77,999 tris, QA'd
|
||||
- `characters/rig-work/mako_tripo_rigbait.fbx` — 78,000 tris, QA'd
|
||||
- `characters/rig-work/` is exempt from the naming grammar (REGISTRY.md rule 11) —
|
||||
disposable carriers, no registry rows. In the game repo it had needed a `.gdignore`
|
||||
to stop Godot importing it, which was the tell that it lived in the wrong repo.
|
||||
- QA renders alongside (`*_qa_front.png`, `*_qa_hand.png`) — fingers fully
|
||||
distinct at 40k, no webbing.
|
||||
- Baits are geometry-only (~3.5 MB; the GLB's packed textures don't survive FBX
|
||||
embed) — AccuRig shows a grey model, which is fine for rigging. It does mean
|
||||
the July "Dummy001 export" check can't use textures: **verify AccuRig's output
|
||||
by mesh name + ~78k tri count instead.**
|
||||
|
||||
**AccuRig exports must be saved as** (same folder):
|
||||
- `characters/rig-work/lena_tripo_accurig.fbx`
|
||||
- `characters/rig-work/mako_tripo_accurig.fbx`
|
||||
|
||||
## Open before execution
|
||||
|
||||
- Step 3 (AccuRig) — manual, waiting on Jeremy/Ozlem.
|
||||
- Step 4 graft script — build once a rigged FBX exists to test against.
|
||||
- Whether to restore the female FBX's `.fbm` texture folder from git (only needed
|
||||
if the FBX is ever used for more than rigging; the lane says it shouldn't be).
