Rubidium Toolkit
Rubidium Toolkit is a Forge client-side utility that extends the Rubidium rendering mod with a set of optional dynamic lights, entity distance and display options.
What it does
Rubidium Toolkit needs Rubidium to run, and it is a client-side only mod, so only the player's client needs it and a server can run without it. Forge is the only loader it is published for, covering the 1.16.5 – 1.18.2 range with four release versions. Its latest file, mc1.18.x-v1.0.0 for 1.18.2, dates from 2023-02-03 and sits on the beta channel.
The toolkit groups several features that were previously separate forks, including a dynamic lights variant, an entity distance setting, and the display FPS and true darkness options carried over from the mc1.16.5-v1.0.4 build. Embeddium (Rubidium) Extra and TexTrue's Rubidium Options are optional companions that add more configuration on top. The code is open source under the GNU Lesser General Public License v2.1 only, and public links to the source and issue tracker are available.
Key features
Dynamic lights
Adds a dynamic lights option that lets held items and entities emit light while moving through dark areas.
Entity distance control
Adjusts how far away entities are rendered, giving the player a way to trade draw distance for frame rate.
Display FPS option
Shows the current frame rate on screen, carried over from an earlier build of the toolkit.
True darkness option

Use cases
Tuning rendering on a modded client
A player running Rubidium can add these options to adjust lighting and entity rendering without installing separate forks.
Checking performance
The on-screen FPS counter gives a quick reading while testing different rendering settings.
Who it’s for: Players who run Rubidium on Forge 1.16.5 – 1.18.2 and want lighting and rendering options in one client-side package. The mod has no effect on server gameplay.
