How would I create a realistic first person view?

Hello, I would like a to implement a realistic or “true” first person perspective into my game, similar to Arma’s, where a camera is simple attached to the player’s head, but less shaky and a bit more like a normal first person view. The closest thing would be Heroes and Generals, you can read more about it here.

So how would I have a realistic first person perspective that is also smooth and fun to play the game with?

The basic method requires attaching a camera the actual mesh of the player.
You can adjust the final output (e.g. smooth out jolts etc) in your Player Camera Manager.

Search the forums for ‘true first person’.
