Light and Dark Hell

by Imaginarium__

Light and Dark Hell changes the lighting of the Nether and the sky, so that the dimension is lit only by light sources.

NeoForgeClient-side onlyApache License 2.01.21.1

What it does

The mod alters how light is calculated in the Nether. Sources such as torches and other light-emitting blocks are the only illumination, and everything else stays pitch black. The sky turns a blinding white, so a player starts with a single torch and has to make it last. Fog is reduced, which makes navigating the dimension harder.

The effect works by hooking into Minecraft's own light map shader uniforms, so it changes lighting without replacing textures. Iris and Oculus shaderpacks can have some of their settings replaced in certain spots, and optimization mods that leave the vanilla lighting pipeline in place have not been widely tested. The mod is for NeoForge on 1.21.1 and is installed on the client only, so servers do not need it.

Dependencies are optional. YetAnotherConfigLib (YACL) adds a settings screen, while the mod still runs without it. Configuration has to be adjusted by hand for the options that are not exposed in the screen, and the author notes the settings are not self-explanatory.

Key features

  1. Light-only illumination

    Only light sources emit light in the dimension, so everything else stays dark.

  2. White sky

    The sky is rendered as a blinding white expanse, a sea of nothingness above the Nether.

  3. Reduced fog

    Fog is lowered in the Nether, which limits how far players can see while navigating.

  4. Shader uniform hook

    The lighting change is applied through Minecraft's light map shader uniforms, rather than through texture replacement.

Who it’s for: Players who want a darker, harder Nether with lighting that differs from vanilla, and who can accept manual config tweaks.

Questions

Does Light and Dark Hell need YetAnotherConfigLib?

No. YetAnotherConfigLib (YACL) is an optional dependency. It adds a settings screen, but the mod runs without it.

Does the server need Light and Dark Hell?

No. Only the player's game needs it, and servers run without it.

Can Light and Dark Hell be used with shaderpacks?

Shaderpacks for Iris or Oculus may be overridden in particular cases, so the lighting may not appear as intended with them.

What the author says

The sky is blinding white. Everything else is pitch black. The only light in this world is the light you carry. A world reduced to Silhouette, isnt it frightening how far a simple change can go?
