Loot Beams Up - Bright Beams for Items

A Minecraft 1.21 Fabric mod that adds colorful and customizable light beams to dropped items! This client-side addition works even on vanilla servers and servers without the mod installed.

Main Features

All items receive light beams by default, with colors depending on the item's name. You can configure whitelists and blacklists for beams, override colors, and even use NBT tags to change their appearance (for example, "lootbeams.color:"0xFFFFFF").

Beams are accompanied by name tags that appear when looking at an item or crouching - you can identify items without even picking them up.
