1st person means you are looking out of the eyes and you can't see the character model :-)
This is because the camera will zoom in that far that you cannot see your cahracter model, it is a camera setting not the model that disappears as I understood it.
So you won't be able to see the charackter if you zoom in to first person.
Nevertheless this makes no sense for me at all? How would you be able to see the charackter in 1st person view at all? The only thing you'll see is the hands (which are shown) and the fett maybe if you would be able to look down at 180°. I didn't test this so far
Or maybe I just don't understand what you are thinking off?
EDIT:
I just saw your first person werwolf addon and now I think I understood what you meant and why you want the model in 1st person view.
But this won't be a 1st person but 3rd person again. The camera would show you the view from teh head (the eyes) but you can see yourself from behind including the werewolf.
I think this won't be possible as the camera is rotating/moving on fixed axis and you just zoom ina nd out to gain 1st or 3rd person, or 3rd person far behind views + changing the FOV to see more from the left and right parts of the screen.
