How to Switch Weapons Between Your Back and Waist
By default, the Item On Back Texture Pack renders weapons in a single location, but you can configure the pack to wear your gear either slung across your back or holstered at your waist.
Changing the Display Position
You do not need to install a separate file to move your weapons; the pack uses Minecraft's built-in resource pack subpack menu.
1. Open the Minecraft settings menu from the main title screen or your world's edit menu (you cannot change active resource pack subpacks while already loaded inside a world).
2. Navigate to the Resource Packs section and open your Active packs list.
3. Select the Item On Back pack and click the gear or nut icon that appears next to it.
4. Move the slider to choose between the On back and On waist positions.
5. Exit the menu and load into your world to apply the new placement.
Affected Items
Changing the position setting does not move every single item supported by the pack. Only swords and axes will shift between your back and your waist when you adjust the nut setting. All other supported items, including the arrow quiver, remain in their default display positions regardless of which option you select.
