Key Features

Open Backpacks

Open backpacks via right-click or the default B key.

Equip Options

Equip backpacks in the chestplate slot or Curios back slot; optional trinket-only mode.

Configurable Tiers (config/inmis.json)

Tweak slot counts, add custom backpacks, require armor slots, and more.

Built-in Migration from MrCrayfish’s Backpacked

Toggle importBackpackedItems to True.
Auto-login migrator (autoBackpacked* config) converts backpacks automatically upon world load/server login.
Use /inmis convert_backpacked command for manual/targeted conversions.
Backpacked recipes are auto-disabled while the importer runs, preventing new legacy stacks.
This requires both mods to be present, once converted you can disable Backpacked and toggle importBackpackedItems to False

Backpack Upgrades

Backpack Upgrades: backpacks now support upgradeable augments with a dedicated UI to control them.
New upgrade UI: toggle upgrades on/off per backpack, view descriptions, and change settings directly in-game.
Configurable upgrade settings: adjust modes and filters for upgrades like Funnelling, Seedflow, and Hopper Bridge.
Available upgrades: Funnelling, Quiverlink, Farmhand, Lightweaver, Lootbound, Imbued Hide, Immortal, Reforge, Seedflow, Hopper Bridge. Upgrade filters: add/remove item filters for relevant augments using the backpack’s contents or held item.
