About this project
What does Water Light Level add?
Water-Light-Level
🌊Water Light Level is a client-side Fabric mod that visualizes underwater blocks whose light level is below a configurable threshold.
It renders a translucent aura around qualifying water blocks, making it easy to:
- spot drowned-safe areas
- identify dark underwater regions
- explore and debug underwater lighting
✨ Features
- 🔦 Highlights water blocks below a chosen light level
- 📏 Configurable scan distance
- 🎨 Customizable aura color (ARGB)
- ⌨ Toggle the aura on/off instantly
- ⌨️ Toggle the aura via a keystroke

🧭 Commands
All commands are under:
/waterlightlevel
Light Level
/waterlightlevel lightlevel <level>/waterlightlevel lightlevel
Sets or gets the maximum light level a water block may have to be highlighted.
Scan Distance
/waterlightlevel distance <distance>/waterlightlevel distance
Controls how far around the player the mod scans for water blocks.
Aura Color (ARGB)
/waterlightlevel color_argb <alpha><red><green><blue>/waterlightlevel color_argb
Customize the aura color and transparency. Value need to be in HEX.
Toggle Aura
/waterlightlevel on/waterlightlevel off/waterlightlevel toggle
or just use the toggle keybind (L by default)
Turns the aura on / off or toggles it.
Aura Only
/waterlightlevel aura_only
Scans the water once and renders the result. Good for large distances that would generate lag if continuously scanned.
Updates on the waters light level will obviously not be taken into account when this setting is on.
