Create a Maya USD model

Import and export support

Maya's round-trip USD import and export process lets artists import USD data as intrinsic Maya data or export intrinsic Maya data as USD data. Artists can use Maya's tools and workflows to create and export models for their USD pipeline and re-import it to make further edits, if necessary. This method implements:

• Material import (USD Import Options) and export support (USD Export Options)
• Command line support for import (mayaUSDImport) and export (mayaUSDExport) operations
• Import and export support for face component tags of meshes (note: a componentTag is encoded as a GeomSubset primitive)
  • Note: Edge/Vertex component tags are currently unsupported.
• Import and export of Maya lights (directional lights, point lights, spot lights and area lights) and light attributes (color and intensity, light-object linking, shadow linking and falloff focus, cone angle, and IES profiles)
• USD File Formats: Exporting USD file types in ASCII (.usda, human-readable) or binary format (.usd or .usdc, encoded machine-readable)
