More Darkness

More Darkness makes Minecraft nights and caves feel truly dark. The moon phase dynamically affects nighttime brightness — full moons cast a dim glow, while new moons plunge the world into near-total darkness. Caves without light sources become pitch black.

Features

• Moon phase lighting — Night brightness follows the 8-phase lunar cycle. Full moon is the brightest, new moon the darkest.
• Pitch black caves — Underground areas with no light source are completely dark by default.
• Per-dimension control — Enable or disable darkness independently for the Overworld, Nether, and End.
• Configurable minimum brightness — Set a floor for nighttime light (starlight, atmospheric glow) so new moons aren't completely black.
• Cave ambient light — Add a faint ambient glow in caves if full darkness feels too harsh.
• Shader-aware — Automatically disables itself when an Iris or OptiFine shader pack is active, since shaders handle their own lighting.
• Polytone compatible — Works alongside Polytone and resource packs that provide custom lightmaps.
• Respects vanilla effects — Night Vision, Conduit Power, and lightning flashes behave normally.
• Client-side only — No server installation needed.
