Lighty Mod (1.21.11, 1.20.1) – Light Overlay with A Twist

Lighty Mod helps players read spawn-safe and dangerous areas more clearly by turning block lighting into a visible overlay. Instead of relying only on standard crosses or numbers, it can display a transparent carpet-like marker, while still allowing a switch back to the traditional view. The mod also includes adjustable brightness and display distance, with F7 opening settings mode and F8 providing a quick on/off toggle.

Key Features

  • Replaces the usual light overlay style with a transparent block that mimics a carpet.
  • Lets players switch back to the traditional display with numbers or crosses if preferred.
  • Uses color-coded danger levels: green for complete safety, orange for areas where mobs may appear at night, and red for areas where mobs can spawn at any time.
  • Includes adjustable settings for brightness, display distance, and other visual options.
  • Provides quick controls with F7 for settings mode and F8 for fast toggling.
