Currently it does not seem like Create supports UsdGeomBasisCurves type objects in a USD stage. For example opening the example UsdGeomBasisCurves stage that comes with USD API does not render correctly in Create:
USD/extras/usd/examples/usdGeomExamples at release · PixarAnimationStudios/USD · GitHub
Will there be support for UsdGeomBasisCurves in Create and if so when might that happen? Thanks.
