About

Heirlooms gives your crafted items a history, then lets you display them like keepsakes
inside your world.

  • Adds craft-date and creator-name tooltips to unstackable crafted & enchanted items
  • Keeps the extra tooltip hidden until CTRL or ALT is held
  • Works with crafted, smithing-table and enchanting-table items from other mods
  • Adds Display Cases and Display Racks for showing off your favourite items in-world

New Tooltips

Your unstackable crafted items get a special tooltip showing:

  • the date the item was crafted
  • the name of the player who crafted it

New Blocks

Heirlooms adds two new blocks, which are perfect for holding your favourite items and elevating their symbolic importance:

  • Display Case - showcase your items in a glass enclosure
  • Display Rack - show your items on a wooden rack

Both blocks show information about the item, including the tooltip information the mod adds, when a player looks at the block in-world.

Tooltips

Any item that you craft which can't be stacked will receive an heirloom tooltip. Popular examples would include tools, weapons and armour.

Iron Sword and Netherite Chestplate recipes

Hidden by default

The tooltip information is only shown when holding down the CTRL or ALT keys while hovering over the item.

Supports modded items

As long as the item is made in a crafting table or a smithing table, or enchanted in an enchanting table, it should work, no matter the mod.

Blocks

Heirlooms adds two blocks to show off your items with:

Display case and display rack isometric 3d models

Display Case

The display case is a full-sized block and shows items on the wooden plate in the center.

  • Perfect for blocks

Display Case Example

Display Rack

  • Perfect for tools, weapons, armour

Display Rack Example

Rendering Differences

The display case and rack render some items differently to each other. If an item is a block with a custom item texture (e.g. sugar cane, torch, sign) the display case will show the block model, while the rack shows the gui sprite:

Frequently Asked Questions

Heirlooms server crashes on startup – what to do?

Heirlooms officially supports fabric, forge, neoforge for Minecraft 1.21.11, 1.21.10, 1.21.9. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Heirlooms – how to optimize performance?
