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).

# Piupiu v3 — re-cut for leg clearance.
|
|
#
|
|
# python tools/md_bridge.py --file tools/tailor/md_piupiu_v3.py --timeout 600
|
|
#
|
|
# WHY v3 (v2 stays untouched; backup in tools/tailor/backup/2026-07-31-pre-v3/):
|
|
# v2's waist edge is 500 mm/panel = 1000 mm total, against Lena's 1095 mm hips —
|
|
# cut TIGHTER than the hip it must pass over, so it drapes as a taut pencil wrap
|
|
# on the thighs. Downstream measures the result: G3 finds 8 mm penetration AT
|
|
# REST, and G5 finds 216-231 verts up to 8.5 cm deep across Idle/Walk, because
|
|
# `weights: "dress"` leaves the sub-hip skirt pelvis-only — the thigh swings, the
|
|
# skirt does not.
|
|
#
|
|
# WHAT THIS CHANGES vs md_piupiu.py:
|
|
# 1. Waist cut to hip + ease (570/panel = 1140 mm) instead of hip - 95 mm, so the
|
|
# skirt is not stretched over the hips, and waist ELASTIC holds it up instead
|
|
# of tension. Doctrine: elastic mid-settle, never from frame 0.
|
|
# 2. Hem flared 1640 -> 2300 mm circumference for standoff at the knee.
|
|
# 3. Additional Thickness - Collision (10 mm) so MD physically resolves the cloth
|
|
# standing off the skin. This is strictly better than the downstream `fit`
|
|
# normal-push (shell_mm 4 / offset_mm 3), which self-intersects in concave
|
|
# regions — i.e. exactly between Lena's touching thighs.
|
|
#
|
|
# HONEST LIMIT: a knee-length pelvis-locked skirt cannot be fixed by clearance
|
|
# alone. Hem target 0.45 m sits 0.495 m below the hip pivot, so a 30 deg hip
|
|
# flexion sweeps the leg ~25 cm forward — more than any believable piupiu
|
|
# silhouette clears. This buys the runtime skirt-bone capsules (`weights:
|
|
# "skirt_bones"`, the concurrent session's lane) room to work, and it should
|
|
# eliminate the rest-pose failure outright. It is not a solo fix.
|
|
#
|
|
# QC targets (unchanged, tools/tailor/qc_placement.py verifies):
|
|
# waistband top 1.05 m +-3 cm, hem 0.45 m +-4 cm (just below knee)
|
|
# G1 measured v2 at +8 cm / +14 cm off these, so v3 should improve placement too.
