Light Up!
by noramibu
Light Up places light sources around players, so caves and surfaces brighten and mobs have fewer dark spots to spawn in.
What it does
Light Up is a server-side Fabric mod that controls lighting through commands. A command sets the range and minimum light level, the skylight option, and whether the work targets surface, cave or all areas. Players can undo their most recent lighting task, and progress is shown as an action-bar message whose toggle and format can be changed in the configuration.
Only the server needs the mod, and players join without installing anything. Light Up is published for Fabric, NeoForge and Quilt, in builds that cover 1.19 – 26.3, with snapshot builds also published. Its source code is released under the MIT License and the code is open source, and the project has a public issue tracker.
Key features
Command-driven lighting
A single command sets the range, minimum light level, skylight behavior and whether surfaces, caves or both are lit.
Per-player undo
Each player can reverse their last lighting task without affecting placements made by other players.
Progress messages
An action-bar message reports lighting progress, and its toggle and format can be configured.
Live-reloaded JSON config
Settings live in a JSON file that reloads while the server runs, so changes apply without a restart.

Use cases
Lighting cave systems
Operators can brighten underground passages in bulk so that players can navigate and build safely.
Reducing mob spawns
Lit areas leave fewer dark tiles for hostile mobs to spawn on, which helps keep settled zones clear.
Who it’s for: Server owners and operators who want to light large areas with commands, and survival or adventure servers where players expect protected, visible spaces around their builds.
