About Lumarit shaders

Your everyday lens for Minecraft.

Lumarit started from one idea: playing Minecraft should feel like holding a camera. Every setting, from depth of field to colour, is tuned the way a photographer would think about a scene, not just to make it "prettier".

Features

  • Volumetric fog & mist: low valley fog, rain haze and thick atmosphere that changes with the time of day
  • Volumetric clouds: soft, lit clouds that glow at sunrise and sunset
  • Physically based sky: realistic atmospheric scattering and golden-hour light
  • Auroras: northern lights dancing over snowy biomes at night
  • Water: reflections and waves that mirror the sky
  • Depth of field: cinematic background blur, like shooting wide open
  • Lens effects: bloom and sun glare
  • Filmic colour: a custom colour grade inspired by classic rangefinder cameras
  • Dimension atmospheres: unique fog and lighting for the Nether and the End
