: A popular choice that allows you to see your 3rd-person body, shadow, and weapons by tweaking camera .ini settings. It requires manual activation by zooming in from the 3rd-person view until the camera passes through your character's head.
The most popular implementation of this is not a single file but a combination of or BodyTalk V2 merged with a first-person legged skeleton.
If you use Gun Reload Sounds Overhaul or Custom Weapon Animations that rely on the vanilla first-person arms, they will break. You need animations that are tagged for the "full body" skeleton.
