Halo 4 3D Models

Can anyone give me some models for halo 4, of anything? Preferably the Multiplayer Infinity Spartan with customizable armor and skins, and someone please tell me ways to import OBJ’s into Source FilmMaker properly and maybe Cinema 4D, I forgot because I can import some models into C4D but there is and issue and none of the limbs are connected and all of the other armor pieces are there instead of a single set and I have no idea how to get them into SFM. Help please or feedback?

PS Check out my last post on the big HALO 4.
