The Building Backpack (formerly "Builder's Backpack") is a portable storage utility added by Forestry. It can hold Glass, Torches, Brick Stairs and Fences.



The Forestry backpacks have four modes. These modes can be toggled by crouching/sneaking and right clicking with the backpack in hand. The four modes are Normal Mode, Locked Mode, Receiving Mode, and Resupply Mode.

  • Normal Mode will automatically input picked up items as long as they are accepted in the backpack and there is space for them. Crouch/sneak-right clicking a chest with this mode enabled will dump all the backpack's contents into the chest.
  • Locked Mode will not pick up items. Chest interaction is the same as Normal Mode.
  • Receiving Mode will act the same as Normal Mode, except that chest interaction will put permitted items into the backpack rather than out.
  • Resupply Mode is the same as Normal Mode in both item pickup and in chest interaction. However, it will keep corresponding items in the player's inventory stocked to a full stack as long as possible.

The Building Backpack can also be upgraded into the Woven Building Backpack.
