# Female model, Windows 1.26

The active female catalogue is models/atlas-female-slim.json (2,324 meshes). It retains 66 HRA female breast, reproductive, uterine-vessel and pregnancy meshes; 2,204 BodyParts3D internal references; 52 Z-Anatomy facial muscles; one adapted BodyParts3D skin; and the BodyParts3D lip FJ2814. The lip receives the same alignment and contours as surrounding anatomy, retains its original topology, and uses an opaque rose-colored material. It accompanies the muscle layer in both sexes and remains individually selectable and isolatable. The former HRA whole-body skin (VH_F_skin) is absent from this catalogue. Original source files and historical catalogues remain available for reproducibility.

Every retained tissue uses one additional continuous presentation field on top of the 1.25 assembly: 6% narrower and 10% less deep across most of the body, with an additional 2.5 percentage-point waist taper. The field fades to identity at the head and feet. Height and internal triangle topology are unchanged, including the 1.18 pelvic-floor correction. Normals use the inverse transpose of the deformation Jacobian. This is an artistic presentation adjustment, not a validated reconstruction of female anatomy.

The skin begins with BodyParts3D FJ2810, using exactly the same original donor fit, 1.19 contour and new shared contour as its internal assembly. Its original external male genital surface is removed and the cut boundaries are closed with neutral patches. Those patches are not anatomical female external genitalia. The chest surface is fitted around the retained female breast tissues with a small clearance. Only the skin receives these two local surface adaptations. The simplified source skin already contains seams; the adaptation adds no new open edges. See models/female-slim-report.json for source IDs, transforms and patch details.

Skin is rendered at 10% opacity (90% transparent), without depth writing, and remains visible alongside internal layers. Body view and female startup show the skin, skeleton, muscles, sensory organs, connective tissue, breast fat and glands (853 pieces). All shows 2,316 pieces, including skin, while the eight pregnancy references stay hidden. Body surface can be toggled independently. Muscles shows 454 muscles plus the lip (455 pieces). Skin does not block picking of visible internal anatomy, and remains on while searching until isolation is enabled.

Breast fat with nipples/areolae (eight meshes) and mammary lobes/ducts/sinuses (six meshes) retain independent switches. Fat stays muscle-red and 50% opaque when glands are visible; glands are yellow and ducts cream. The two native suspensory ligaments remain in their original integumentary classification. Search, isolation, rotation and zoom remain available. Original male geometry, layer behavior and reproductive structures are unchanged.

This remains an approximate mixed-donor educational reference. All 38 female reproductive structures are retained. The male urethra is excluded; no female urethra mesh is available in the source. Existing eye geometry is not duplicated. Source licenses and attribution are retained: BodyParts3D CC BY 4.0; HRA CC BY 4.0; added Z-Anatomy facial geometry and adaptations CC BY-SA 4.0.
