# 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 Help; SARKAMARI [00:29:22]; Stamatelos [00:30:21]). MPM `detail_size` is in meters, so a unit change silently changes resolution (Gast [00:07:29]). - **Never simulate the production mesh.** Duplicate the skinned body and garment, drive the duplicates with a blend shape at weight 1, hide the originals (SARKAMARI [00:10:04]). - **Give the solv...
