Tattoo test bed: Quaternius v3-v6 bakes + Lena pipeline (bake, de-mirror, re-UV, viewers)
Session 2026-07-23/24 additions on top of the existing Quaternius bed: - bake_lena.gd: 6-piece bake on QuatSkin Lena (chiefs-mark/iron-spine arms, voyagers/storm-bearer legs, star-eye chest, hearth-warmth back); global-axis wrap frame + 3cm junction blend kill the elbow split line - demirror_lena.gd: tri-level split of mirror-shared limb UVs (arms 100%->0%, legs 99%->5% crotch-only residual) - reuv_lena.gd: Quaternius-style semantic re-UV (16 islands, cylinder limbs + cylinder head/torso with planar caps) + texture transfer; fixes armpit/chin/ cheek planar smears; single 4096 atlas, per-side tattoos native - main_lena / anim_lena viewers (18 UAL clips, U light toggle) + probes + shots Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
