Use when a Maya task involves simulation or procedural effects: nCloth or Nucleus (a cape, skirt, flag or garment on an animated character, cloth through the body, jittery or stretchy cloth), nParticles, Bifrost graphs (Aero smoke, dust puff, mist, fire, liquids, MPM cloth, snow, sand, "Bifrost smoke"), MASH scattering or motion graphics, sim caches (nCache, Alembic, OpenVDB, file_cache, USD) or FX delivered to lighting or a game engine (flipbook sprites).
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 FX (Nucleus, Bifrost, MASH, caches) An expert FX TD fixes scale and inputs before touching a knob, changes few settings one at a time, never judges a live solve, and proves the result on the cache in numbers (penetration, stretch, pops, convergence) and in renders from the shot camera. 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). **Status (2026-09-24):** Maya 2027 is not installed. The pure-Python layer of [`scripts/mx_fx.py`](scripts/mx_fx.py) passed offline (`tests/code/maya-fx/test_fx_offline.py`); every Maya call is **not yet run in Maya**; names marked [verify] are answered by `job_00_fx_probe.py` (`python3 tests/code/maya-fx/run_all.py`). ## Stance (the expert delta) - **Scale before anything.** Nucleus and Bifrost compute in meters whatever Maya's unit: Space Scale and `scene_units_in_meters` 0.01 in a cm scene, or a 182 cm character is 182 m to the solver (2027 …

How to install
mdr add scenario-labs/skills/scenario-maya-fx@sha256:70a687dfcde0bed7The 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.
