# maya-asset-sync

Typed cross-DCC revision sync using the shared `dcc-mcp-core.asset_sync` contract.
Filesystem roots are operator-owned environment configuration.

`sync_usd_revision` offers two deliberate editability modes:

- `native`: MayaUSD imports hierarchy, joints, animation as native Maya curves,
  geometry and shader networks for direct editing.
- `usd_proxy`: a `mayaUsdProxyShape` references the immutable layer and retains
  maximum USD composition fidelity for non-destructive layer edits.

The result reports native animCurve, joint, NURBS curve, material, texture and
bounding-box evidence so callers can verify what remained controllable. Native
material evidence also identifies imported Arnold `standardSurface` PBR
materials, their metalness, specular roughness, IOR, transmission, coat, and
connected shader inputs instead of treating a material count as proof of
lookdev fidelity.

`rig_expectation` makes rig preservation auditable instead of best-effort:

- `auto` preflights the USD and requires Maya joints whenever a standard
  `UsdSkelSkeleton` is present.
- `skeleton` requires both source `UsdSkel` data and imported Maya joints.
- `skinned` additionally requires authored joint indices/weights and imported
  Maya `skinCluster` nodes.
- `ignore` keeps the legacy permissive behavior for intentionally rigid assets.
