Cameras

The enabled option will import cameras present in the USD scene. The common camera parameters such as projection type, focal width, focal distance, clipping, f-stop, etc., will be assumed.

Geometry

Activate this option if you want to import geometry that is saved in the USD file. Several simple object types such as Cube,  Sphere, Cone, etc., will be imported into Cinema 4D as Primitives.

Meshes will be imported as triangles/quads, either with UV coordinates, Normals or Display Color.
