Description#

This feature adds the NVIDIA RTX semantic-label conventions on top of the Standard semantic-label contract. An asset that satisfies this feature carries a non-empty SemanticsLabelsAPI:material label on every UsdShade.Material prim, so RTX sensor and perception workflows can produce material-segmentation ground truth in addition to object/class ground truth, and it keeps every semantic label static.

Object labels describe what a thing is; the material taxonomy describes what it is made of. Both coexist on the same asset through the SemanticsLabelsAPI multiple-apply schema.

The RTX perception pipeline samples one constant label per object, so time-sampled label values are a pipeline limitation rather than invalid USD. Time-varying labels remain legal under the neutral FET_011_STANDARD contract; they only fail here.

Requirement List#

Pipelines#

Source file type:

  • .usd, .usda, .usdc

    • Author SemanticsLabelsAPI:material and semantics:labels:material on each UsdShade.Material prim, with no time samples on any label attribute.

Validation or runtime pipeline:

  • SimReady validation - verifies the SL.MAT.001 material-label and SL.TIME.001 static-label contract.

  • Semantic Labels Check - confirms labels resolve to constant values at runtime.

Samples#

  • None.

Benchmarks#

Adapters#

None.
