_USDKit_RealityKit cross-import overlay

iOSmacOStvOSwatchOSvisionOS

_USDKit_RealityKit is a cross-import overlay that adds deformation and skeletal animation support for USD-based 3D models in RealityKit. Use it to drive USD content with USDPlayer and USDStageComponent, and to work with the geometry, materials, and textures described by types such as MeshData, MaterialData, TextureData, and DeformationData, each paired with an identifier like MeshID, MaterialID, or DeformationID. Rendering feedback surfaces through TextureLevelInfo, UsdRenderMessage, and USDRenderError. The overlay is available on iOS, macOS, tvOS, and visionOS.
