Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 26.1–26.1.2Newest
Minecraft 1.21–1.21.11
Minecraft 1.20.1–1.20.6

⬇ Download for 26.1–26.1.2 ⬇ Download for 1.21–1.21.11 ⬇ Download for 1.20.1–1.20.6

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

LuckPerms InventoryWeight

LuckPerms InventoryWeight is a server-side add-on for MT Inventory Weight and LuckPerms.

It lets server admins give players more maximum inventory weight through LuckPerms rank/user meta values.

This mod is not standalone.

Required Dependencies

This add-on requires:

Server-side Only

LuckPerms InventoryWeight is designed to run on the server.

It does not add client UI, keybinds, screens, HUD elements, or tooltips. It only modifies the server-side max weight calculation used by MT Inventory Weight.

Features

Supports direct multiplier bonuses
Server-side only

Supported LuckPerms Meta Keys

The add-on reads these LuckPerms meta keys:

inventoryweight.maxweight.add
inventoryweight.maxweight.percent
inventoryweight.maxweight.multiplier

Flat Bonus

/lp group vip meta set inventoryweight.maxweight.add 50

Gives:

+50 max weight

Percent Bonus

/lp group vip meta set inventoryweight.maxweight.percent 25

Gives:

+25% max weight

Multiplier Bonus

/lp group vip meta set inventoryweight.maxweight.multiplier 1.5

Gives:

1.5x max weight

Formula

The final result is calculated like this:

final max weight = (current max weight + add) * (1 + percent / 100) * multiplier

Example:

Current max weight: 100
Add: 50
Percent: 25
Multiplier: 1.5

Final: (100 + 50) * 1.25 * 1.5 = 281.25

Example Rank Setup

/lp group default meta set inventoryweight.maxweight.add 0
/lp group vip meta set inventoryweight.maxweight.add 50
/lp group vip meta set inventoryweight.maxweight.percent 10
/lp group elite meta set inventoryweight.maxweight.add 100
/lp group elite meta set inventoryweight.maxweight.percent 25
/lp group elite meta set inventoryweight.maxweight.multiplier 1.5
