The geometry in this scene is a grid of grids. The top-level grid is
made up of USD proxy shape nodes. Each of those proxy shape nodes
references a USD file that contains a single Mesh prim that is a grid
of cubes. This single cube grid mesh is the result of combining the
grid of cube asset meshes referenced from the "ModelRefs" test below.
The camera in the scene is positioned in a side view.
