Use USD import to read Universal Scene Description (USD) assets as static models or start shapes. It supports .usd, .usda, .usdc, and .usdz file extensions and recognizes the USD mesh and cube node types. USD import can read scenes consisting of more than one .usd file; see the USD export file structure for more information. Additionally, for static models, if the USDPreviewSurface material type is present, they are displayed as CityEngine PBR Material.
