Use when skinning a character in Maya ("bind skin", "fix the weights", weight painting, Skin Tools or ngSkinTools layers), when deformation looks wrong (pinching, candy-wrapper wrist, collapsing elbow or shoulder, volume loss, clothes poking through), when mirroring, copying or capping skin weights for Unreal or Unity, building blend shapes, corrective shapes or pose space deformation (Pose Editor on IK-driven joints), a face rig with shapes or joints, multiple skinClusters, Delta Mush or the…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Maya deformation (character TD)

Expert deformation is decided before the first weight: joint pivots and edge loops set what skinning
can do. Weights are then built region by region, judged in motion at extremes with numbers and
renders, and every fault is fixed where it originates. Stance: block rigid, diagnose, smooth and
shape, correct what weights cannot, and keep everything regenerable as data. If a sibling skill
named here is missing from your available skills, ask the user to install it
(`npx skills add scenario-labs/skills --skill <name>`); unattended, proceed from tool schemas and
flag the gap.

**REQUIRED BACKGROUND:** scenario-maya-expert (execution channel, review loop, 2027 version traps).

Module [`scripts/mx_skin.py`](scripts/mx_skin.py): weights IO, region blocking, masks, mirror,
transfer, ROM generator, deformation metrics, correctives, Skin Tools wrappers. **Status
(2026-09-24):** its pure-Python half ran offline (`test_mx_skin_offline.py`, all pass); every Maya
call is **not yet run in Maya** (tests: `tests/code/maya-deformation/run_all.sh`, via `mx_run.py`).
`import sys; sys.path.insert(0, "<skills>/scenario-maya-deformation/scripts"); import mx_skin as S`

How to install

The exact contents, by fingerprint
mdr add scenario-labs/skills/scenario-maya-deformation@sha256:c76c0240d8050dce

The line at the top of this page pins the label git:20261017.88ccf82, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
