基于 SOC 职业分类
Domain skill for authoring and inspecting OpenUSD stages. Create a stage, list prims, define Xform prims, set xform operations (translate/rotate/scale), modify stage metadata (upAxis, metersPerUnit, framesPerSecond), and add reference arcs to external assets. Create portable UsdGeom.Mesh polygon topology and UsdGeom.Points primitives for particles and point-based FX.
Domain skill for creating cameras and lights in an OpenUSD stage. Create UsdGeomCamera, DistantLight, SphereLight, HDR DomeLight, and set transforms or visibility on prims.
Domain skill for USD material authoring. Create UsdShadeMaterial prims, attach PBR UsdPreviewSurface shaders, and bind materials to geometry prims.
Domain skill for animation time samples. Set stage time codes and author translate/rotate/scale samples on Xformable prims as well as arbitrary attribute time samples.
Domain skill for creating and maintaining self-contained OpenUSD project folders with scene.usda, assets, materials, lights, packages, and snapshots. Use before authoring a new OpenUSD stage or when resuming a portable project.
Infrastructure skill for validating OpenUSD stage invariants and packaging a stage into a USDZ-style archive. Use after authoring or before handoff.

Manage layer composition arcs: add sublayers to the root layer, attach
payload arcs on prims, create variant sets, and set variant selections.
Reference arcs remain in openusd-stage. Requires the pxr OpenUSD runtime.
add_sublayer — compose another layer under the root layer.add_payload — attach a payload arc on a prim.add_variant_set — create a named variant set on a prim.set_variant_selection — switch the active variant in a variant set.
