The First-person Model mod is a realistic mod that will enable the player’s model to be displayed in the first-person view, so you will see your legs, arm and their usual game movements. This will make the game much more realistic.
The mod works with other mods that change motion animations, for example MoBends (although at the moment the mod is not available for this version of the game and factories).
How to install the mod:
Install Fabric API
Install all additional mods if specified.
Download mod and copy to .minecraft / mods
In the launcher, launch the version of the game with the factory.
