+ Authoring stage - Maya dynamics: classic rigid bodies and force fields plus

+ the Nucleus family (nCloth, passive colliders, Nucleus constraints, the

+ nucleus solver) and nCache write/delete. Use for simulation setup steps

+ before baking with maya-animation. Not for particle systems

+ (maya-particles), Bifrost graphs (maya-bifrost), keyframe editing

+ version: 1.1.0

+ - ncache

+ connect dynamic field, simulation setup, bounce, friction, mass,

+ nCloth, nRigid, collider, passive collision object, nucleus solver,

+ nConstraint, transform constraint, weld, force field, substeps,

+ space scale, dynamic field, air field, drag field, turbulence field,

+ vortex field, volume axis field, newton field, radial field,

+ nCache, geometry cache, cacheFile, write cache, delete cache

+ Typed wrappers for Maya's classic dynamics and Nucleus simulation commands.

+ Keep this skill focused on small graph mutations that agents otherwise tend to

+ attempt through `execute_python` with fragile command flags.

+ Use `maya-animation.bake_simulation` after the simulation is working and needs

+ to be converted to keyframes for export. Use `maya-particles` when the effect

+ is particle-driven rather than cloth-driven.

+ ## Tool groups

+

+ | Group | Activated by | Contents |

+ |-------|--------------|----------|

+ | `dynamics` | `activate_group("dynamics")` | Classic rigid bodies and field connections |

+ | `nucleus` | `activate_group("nucleus")` | nCloth, nRigid colliders, Nucleus constraints, solver |

+ | `fields` | `activate_group("fields")` | The full dynamic field family |

+ | `constraints` | `activate_group("constraints")` | Classic rigid-body constraints |

+ | `cache` | `activate_group("cache")` | nCache write and delete |

+

+ ## Cloth workflow

+

+ 1. `make_rigid_body` for classic rigid-body work, or `create_ncloth` for cloth.

+ 2. `create_nrigid` on any mesh the cloth should collide with.

+ 3. `create_nconstraint` to pin cloth to a driver (transform, weld, force field…).

+ 4. `create_nucleus` / `set_nucleus_properties` to tune gravity, wind, substeps

+ and `space_scale` — `space_scale` is the single most common cause of a

+ simulation that looks "too slow" or "exploding".

+ 5. `create_dynamic_field` for forces, `set_field_properties` to refine them.

+ 6. `create_ncache` once the motion is approved; `delete_ncache` to iterate.
