MT Inventory Weight
by MEGATREX4
With MT Inventory Weight installed, every item in a player's inventory adds to a total weight that can slow the character down.
What it does
The mod adds a configurable weight system to Minecraft. Items carry a weight, the sum of everything carried is tracked, and carrying too much causes slowness and weakness. Combat can apply an Overload effect once the limit is passed, so the choice of what to carry matters. Weights are set automatically for items by default, and datapacks can override them for specific items and for armor pockets.
The mod is aimed at survival and RPG-style play, where inventory space alone is not the only limit. Configuration uses Fzzy Config, and Mod Menu support lets the settings be changed in game. Servers that run it need every player to install it too. It is published for Fabric, Forge and NeoForge, across 22 release versions, 1.20 – 26.1.2, and is released under CC0 1.0 Universal, so it is open source.
Key features
Automatic item weights
Each item receives a default weight without any setup, and the weights can be tuned in the config.
Datapack weights
Datapacks set custom weights for specific items and change the capacity values of armor pockets.
Overload effect
Carrying past the limit applies slowness, weakness and an Overload effect, which can take effect in combat.
Weight display
A HUD element and item tooltips show the current weight and the weight of each item.

Use cases
Survival and RPG play
Players choose what to carry, because heavy gear and supplies have a real cost to movement and combat.
Modpacks
A pack that depends on resource management can add weight rules without changing the items themselves.
Who it’s for: Players who want inventory decisions to matter, and modpack authors who build survival or RPG-style gameplay around carrying capacity.
