Light Overlay

by shedaniel

Light Overlay shows a light-level overlay on the world, a NEI-like view of where mobs can spawn, toggled with F7.

FabricForgeNeoForgeRiftClient-side onlyApache License 2.0Open source1.13.2 – 1.21.10

What it does

Light Overlay draws a light-level overlay over the world so players can see the light value of the blocks around them. The overlay is a NEI-like view, and it can be switched on and off with the F7 key. The key can be changed in the Controls settings. The mod has no server side, so only the client needs it.

The mod is published for Fabric, Forge, NeoForge and Rift, across 30 release versions, 1.13.2 – 1.21.10. Its latest files are 13.0.0 for 1.21.10 on Fabric and NeoForge, and 8.0.0 for 1.20 on Forge. The code is open source under the Apache License 2.0. Architectury API and Cloth Config API are required dependencies, and the config screen is reached through the mod list or the loader's menu.

Key features

  1. Light level overlay

    Light values appear over the world, similar to the overlay found in NEI.

  2. Toggle key

    Pressing F7 switches the overlay on or off during play.

  3. Key binding

    The toggle key can be changed through the Controls settings.

  4. Config access

    Settings open from the mod list on Forge and NeoForge, and from the loader's menu on Fabric.

Use cases

Spawn checks

Players can see which areas have light levels low enough for hostile mobs to spawn.

Building and farms

The overlay helps with placing torches or planning lit areas before building.

Who it’s for: Players who want to view light levels in the world while playing. Only the client needs the mod, so it can be added to a single-player world or a client without any server change.
