Autodesk has released USD for 3ds Max 0.3. The plug-in lets the users create, edit, work in, work with and collaborate on USD data while being able to switch across platforms when working on their projects.
The update introduces a new USD Stage Object, which allows directly loading a USD scene without having to import data. The feature is not yet fully implemented as there is no UX for browsing or editing data inside a Stage yet and the Stage Object displays geometry and USD Preview Surface materials, but it doesn't display lights, cameras, and shapes.
