The nice thing about Cinema4D + MoI is that Cinema handles the n-gon .obj export from MoI really well.

You end up getting poly models that have a lot of the same feel as the original NURBS model, they aren't just a big jumble of triangles with a messy wireframe.

Here's one of the early examples of the n-gon export to Cinema4D:

You can kind of see what I'm talking about there - that mesh has more of a "hand-tuned" type feel to it, even though it was generated from NURBS.
