Hi jiro, just a bit more info for you - MoI uses a kind of object called NURBS surfaces and Blender currently uses a type of object called a polygon mesh.

They're different ways to represent objects, so you can't get the exact same structure in blender as you had in MoI until the time that Blender will be able to have NURBS objects in it, which I guess is something that is being worked on.

So that's why your object looks a bit different in blender - when you export to OBJ format it gets turned into polygon mesh data instead.
