Exact USDA block introduced by RCP plus fixture-backed contract evidence.

ID: RealityKit.MeshSorting Baseline: BASE.usda Fixture: Model Sorting

schema.json fields.csv matrix.csv fixtures.csv

Quick Read

ModelSortGroupComponent has 2 fields. None are written in the baseline — RCP uses sparse authoring, emitting each field only when it differs from the engine default.

Authored as def RealityKitComponent "MeshSorting" with info:id = "RealityKit.MeshSorting".

For large components, prefer fixtures.csv for fixture-by-fixture authored rows and matrix.csv for the derived variant matrix.
