Host your Minecraft server on BisectHosting - get 25% off your first month with code MODRINTH.

Instead of rendering crosses or numbers on the top face of blocks, Lighty takes a different approach - It renders a transparent carpet-like block on top! Or, new in version 1.1.0 - Renders the actual light level numbers, but Lighty Style!

  • To activate the overlay, press F7 and choose the desired mode. This key is configurable in the key binds menu.
  • As of version 1.2.0, you can quickly toggle the light overlay on or off using F8! This key is configurable in the key binds menu.
  • As of version 1.3.0, you can change the "red"/"orange" threshold in the new config menu (accessible using F7). Useful for those that want to light their places up aesthetically, or maybe you are playing with some mods that change the mobs spawning rules.

Meaning of colors:

  • Green: No mobs can spawn here!
  • Orange: If the sun goes down, Mobs will spawn! Be careful!
  • Red: Mobs can spawn here!
