Lead Physics Mod reworks the way animal leashes look in the game. It replaces the stiff, straight line of the normal lead with a smooth, moving rope. The mod only changes the visuals, so normal game rules stay exactly the same.

- Gives you control over how strong the rope physics look on your screen.
- Keeps normal game rules the same because all changes are visual.
- Works entirely on your side of the game, so it runs well without slowing down servers.
