When you render, faces with their normals pointing away from the screen (in this case, the inside faces of the cups) are not drawn. This happens because, in most cases, inside faces are hidden by other faces on the shape.
In Lightwave at least, you can go into surface properties and set a surface to be double-facing, allowing all faces to be drawn regardless of normal direction.
In other programs, there's probably some equivalent to that. I'm sure if you ask your professor, they should be able to help you find it.
