Nitrogen
by NitronRbn
Nitrogen is a Fabric library for rendering, supplying shapes, trails, beams and tooltip styling that other mods can build on.
What it does
Nitrogen provides rendering utilities for mods that need to draw extra geometry. Its helpers include a textured sphere, a textured cube, a sky beam effect and entity trails, and a supporter system for extra rendering features is part of the package. Other mods call these utilities rather than drawing the effects themselves, which keeps their own code shorter.
Among the smaller helpers, the mod changes the background color of item tooltips and adds screen shake, so a mod author can call those effects directly. Nitrogen is client-side only: only the client needs it, and a server runs without it. It is published for Fabric alone, with files for 1.21.1, 1.21.5, 1.21.6 and 1.21.10, and the latest file, 1.0-1.21.10, dates from 2025-12-09.
Thaumaturgy, Uwu and Garden of Eden all require Nitrogen, so installing those mods means installing this library as well. The project is released under All rights reserved and is not open source, though its source code, issue tracker and wiki are public.
Key features
Textured sphere and cube
Helpers draw a sphere or a cube with a texture applied, for decorative or UI geometry.
Sky beam effect
A vertical beam rendered into the sky, usable as a marker or highlight effect.
Entity trails
Trails that follow an entity as it moves, rendered through the library's own helper.
Tooltip background color
Item tooltip backgrounds can be recolored through a simple call, with screen shake available alongside.

Use cases
Mod authors
Developers who need shapes, beams or trails in a rendered effect can reuse these helpers instead of writing the drawing code.
Players of dependent mods
Anyone installing Thaumaturgy, Uwu or Garden of Eden needs Nitrogen on the client, because those mods require it.
Who it’s for: Mod developers building client-side visual effects, and players who want the mods that depend on Nitrogen to run.
How it compares
RefinedLib is a Fabric library that runs on client and server and is published under All rights reserved, with a single file for 1.21.1. AcornLib is also Fabric and client and server, under a custom license, with files covering 1.21 – 26.3. Noice Brush is client-side only and MIT licensed, for 1.21 – 1.21.8, so it is a closer match to Nitrogen's environment but offers a different set of features.
