Unfortunately, we refuse to give out our model converter as we would hate for our competition to be able to edit models. This is one one of the primary reasons our models aren't being updated. None of us know how to model edit, but we won't let anyone else do it for us for fear of leaks.
Maybe, just maybe we could convert one for you and you can see what you can do with it. But all three of the admins would have to approve of it.
