A free mod for Monster Hunter World, by UberGrainy.

This extension is made for those of you who are tired of the same look every time you play. You will be able to customize your character’s face in a very subtle way, so you won’t be able to tell that you have a different face.

The only thing that you need to do is install this extension, then go to the options menu of your game, and choose the new face option. You can change the size of the iris, the distance between the eyes, the depth of the shadows around the nose and the brow, the height of the nose, and the lips.
