The exploration release: pick faces from a contact sheet, sculpt by feature zone, step back through every look, drag landmarks live, and export mocap-ready rigs — for Google GNM parametric heads inside Autodesk Maya (Windows / Linux / macOS).
What's new since 1.2.0
- Variants contact sheet — a 3×3 grid of candidate randomizations rendered as thumbnails; click a face to apply it, Re-roll for nine more. Respects the Area/Zone mask, random scale and the Symmetry toggle.
- Feature zones (Nose / Mouth / Jaw / Brows / Eyes) — randomize finer areas than the model's own regions. A fit solver blends the change into a smooth landmark-derived zone and solves back to ordinary coefficients, so sliders, presets and rig baking stay fully consistent. Isolation is soft by design: a small natural falloff halo remains (measured ~1 mm on a 4–17 mm zone change, <0.3 mm far away).
- Area Randomize masks (from the previous dev drop) — per-region checkboxes (head, eyes, lower face, …) so randomize/reset touch only what you choose.
- History ladder (◀ ▶) — step back/forward through every randomize, sample, describe, variant, reset and fit. A good face is never lost again.
- Live landmark fit (drag-to-sculpt) — GNM ▸ Landmarks ▸ Toggle Live Fit: drag the 68 locators and the head re-solves its identity on every drag release.
- ARKit-52 target names on Bake Rig — optional renaming (and Left/Right splitting of symmetric shapes with a smooth midline mask) of the semantic blendshape targets to Live Link Face conventions: eyeBlinkLeft/Right, mouthSmileLeft/Right, cheekPuff, tongueOut, … 28 targets from the 20 GNM expressions; unmapped shapes keep their GNM names.
Install (Maya 2022–2027, Windows / Linux / macOS)
- Download Source code (zip) below and extract it anywhere.
- Drag
drag_and_drop_install.py(top of the extracted folder) into a running Maya viewport. - Accept the first-run setup (Python runtime + GNM model ~40 MB; shape images render locally ~5 min).
The installer copies the module into ~/Documents/maya/modules, so you can delete the zip afterwards. Updating from an earlier version: GNM ▸ Check for gnm-maya Tool Updates, then restart Maya.
Notes
- Linux/macOS need a
python3(3.9+, venv module) on PATH; Maya's own Python is the fallback. Windows is fully self-contained. - GNM is Apache-2.0 (Google); this tool is MIT and not affiliated with Google. See NOTICE.md.
