Modify Utils

Modify Utils is a client-side Fabric mod for making important dropped items easier to spot and harder to drop by accident. It can enlarge selected items on the ground, change how ordinary drops are rendered, and protect chosen items with Item Lock.

Whether you play on a custom server with named gear and tokens or simply want valuable loot to stand out, Modify Utils lets you decide what counts as important and how it should look.

Features

Customize dropped-item rendering

• Change the visual scale of recognized dropped items, from 0.1× to 4.0×.
• Configure built-in items, custom item rules, and enchantment rules.
• Choose how the mod identifies items: by custom name, item type, or both.
• Enable or disable the mod and its Modify Mode independently.
• Turn item shadows on or off.

Choose a render mode

• Vanilla — Keeps ordinary items at their normal size and applies configured scaling to recognized items.
• Performance — Renders ordinary, unrecognized items at a configurable small scale. Recognized items use their configured scale while Modify Mode is active.
• Ultra Performance — Hides ordinary, unrecognized items. Recognized items use their configured scale while Modify Mode is active.
• Near Only — Shows ordinary, unrecognized items only within a configurable distance. Recognized items use their configured scale while Modify Mode is active.

The distance for Near Only and the small-item scale for Performance Mode can be adjusted in the settings.

Protect items with Item Lock

Item Lock can prevent locked items from being dropped using the drop controls handled by the mod. You can:

• Toggle Item Lock globally.
• Lock or unlock a recognized item individually from your inventory or by using the held-item lock keybind.
• Add an unrecognized named item to Custom Items and lock it directly.
• Choose whether locked items show a tooltip, an inventory border, or a chat message when a drop is blocked.
• Set whether an item rule can be locked.

Item Lock is client-side. It controls drops made through the client; it does not change server-side item permissions.

Create custom rules

Add rules for items from vanilla, modded, or custom servers. A rule can match an item by:

• Full item ID, such as minecraft:diamond_sword
• Item path, such as diamond_sword
• Display-name text, including custom names

Each custom item rule can have its own scale, detection mode, and lockable setting.

You can also add enchantment-based rules. Match an enchantment by its ID and optionally specify a level, then set the matching item’s scale and lock behavior.

Make and switch presets

Create named presets that select items and assign per-item scales and lock states. Give each preset its own keybind and choose whether it activates as a toggle or only while the key is held. This makes it possible to switch between different item configurations during play.

Configure everything in game

Open the settings screen through Mod Menu or the settings keybind. The screens include general settings, built-in item settings, custom items, custom enchantments, presets, and rule import/export. You can copy rules as JSON or paste JSON to import them.

Built-in item categories

Modify Utils includes rules for a range of items, including:

• Modify weapons and gear: Dash Sword, Strike Sword, Executioner Sword, Void Sword, Lifesteal Sword, Inhibitor Sword, Knockback Sword, Axe of Protection, Axe of Resistance, Axe of Explosion, Excavation Pickaxe, and Punch Bow.
• Tokens: Kill Token, Compressed Kill Token, Enchanted Token, Mining Token, Compressed Mining Token, Wood Token, Compressed Axe Token, and AFK Token.
• Special items: Enchanted Golden Apple, Chorus Fruit, Wind Charge, Ender Pearl, Blue Ice, Obsidian, Stone Brick Wall, and Spectral Arrow.
• Armor and trims: Trimmed armor and armor trim templates.
• Materials: Iron, gold, copper, and netherite ingots; amethyst shards; redstone; lapis lazuli; emeralds; diamonds; quartz; and resin bricks.
• Other grouped items: Potions, banners, banner patterns, and dyes.

The included Modify names are examples of built-in matching rules. You can add your own rules for other server items.
