How to make fps and 3ps in one

Hello
I do fps game and do not know how to make the view from the first person (to be seen only hands), but as someone else looks at the character sees it all.
you know any tutorial to this?

 

A FPS has a camera attached to the player, so as the player moves, the camera moves with him. What you want to do is move the attached camera away from the player's view - as long as it is still attached to the player it will still follow him, but offset to wherever you move it (ie, back and up a bit looking down towards the player).

 

You could just make 2 cameras and enable one for FPS and one for 3PS.
