Lucem is a small wrapper over Sober to provide some QoL improvements.
Please keep in mind that while Lucem is fully open source software, Sober is proprietary for a very good reason, that being to preserve RoL from 9-year-old skiddies.

Contact/Support

You can open issues for bugs.
We now have a Discord server! You can join it here

Disclaimer, in big bold letters.

Lucem does not allow you to bypass the (reasonable and justified) restrictions the Vinegar team has put on Sober's ability to load APKs that are modified.

If you really cheat on Roblox, I'd say you should reconsider your life decisions than anything.
Lucem is not associated with the VinegarHQ team or Roblox, nor is it endorsed by them!

Features

• GTK4 + Libadwaita GUI to modify settings
• GTK4-based FFlag editor that is easy to use
• Rich presence
• Server region notifier
• Game overlay
• If you're not a fan of GUIs, we provide a nifty configuration file that does the same thing! (located at ~/.config/lucem/config.toml, or you can run lucem edit-config!)
• Managing Sober

Whilst not a feature you use directly, Lucem also caches API calls whenever it can in order to save bandwidth and resources.

Icon

The Lucem icon is made by AshtakaOOf. It is located here.
You are free to use it wherever you want.

Patches

Lucem provides the following optional patches. All of them go under the tweaks section in your configuration.

Bring back the old Oof sound

oldOof = true

Use another font

Both OTFs and TTFs are supported.

font = "/path/to/your/font.ttf"

Replace sun and moon

sun = "/path/to/sun.jpeg"
moon = "/path/to/moon.jpeg"

Force X11 or Wayland to be used

This one goes in the client section!

[client]
backend = "x11" # or "wayland", "wl". This is case insensitive.
