Lucium - Collection of Useful Utilities for Minecraft

The name "Lucium" refers to a historical case from 1896 when chemist Prosper Barrière allegedly discovered a new element in the mineral monazite, but later William Crookes proved it was merely a contaminated sample of yttrium.

What is this mod?

Lucium is a compact set of practical tools originally developed for the Yttr mod, but separated into a standalone project to avoid overloading Fabrication. Particularly useful for developing and debugging other mods, as Fabrication doesn't always work stably in development environments.

For developers' convenience, available via the Sleeping Town Maven repository:

repositories {
    maven {
        url 'https://repo.sleeping.town'
        content {
            includeGroup 'com.unascribed'
        }
    }
}

dependencies {
    modRuntimeOnly "com.unascribed:lucium:1.1"
}

Main Features

Particle Display Fix

The mod renders particles in two passes, like in versions before 1.15, allowing particles to display behind transparent blocks even with Fancy and Fast graphics settings. Compatible with Sodium.

Debug World Fix

Fixes the standard debug world by adding all blocks from installed mods.

Customizable F3 Screen

Use Page Up and Page Down to toggle between elements on the F3 screen. Home and End switch between left and right sides respectively. Delete collapses the highlighted group of elements, and Insert brings back the nearest collapsed element.

Reduced F3 Screen

Reduces the size of the F3 screen by half at GUI scale 3 and above. Proportional reduction coefficients apply at other GUI scales.

Additional Tags in F3

Displays biome and entity tags in debug mode.
