Medieval Realism Shaders
Grounded, period-film lighting for Minecraft. Think candle-lit taverns, misty mornings over a village and grey
overcast rain on wet cobblestone, not a fantasy glow-fest.
Features
- Physically based sky: real sunrises and sunsets, a proper moon, stars and dark, moonlit nights
- Soft shadows: contact-hardening on High/Ultra, and coloured shadows through stained glass
- Firelight: warm torches, lanterns, campfires and candles with a subtle, natural flicker
- Atmosphere: height fog, morning valley mist and volumetric light shafts
- Fluffy volumetric clouds (Medium and up), puffy 2D clouds on Potato/Low
- Rain: wet, darker stone, wood and dirt, with puddles on flat ground
- Water: reflections, refraction, depth-based colour and caustics
- LabPBR 1.3: normal maps, specular, emissive and parallax occlusion mapping, plus good fallbacks for
packs without PBR maps - Filmic grade: AgX/ACES tonemapping, earthy colours, restrained bloom, auto exposure
- Settings menu in English and Português (Brasil)

Recommended resource pack
Patrix 32x (free, LabPBR, built for shaders). Install
Continuity with it, or Patrix's grass shows "ENABLE CONNECT TEXTURE".
For a lighter option without PBR, try John Smith Legacy.
AI disclosure
The shader code was written by Claude (Anthropic) agents in Claude Code, directed and play-tested by me.
