Medieval Realism Shaders

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)

Profiles

Profile · For
Potato · integrated graphics and very old GPUs
Low · low-performance PCs. Low mode is perfect for them; the author plays on a Radeon RX 550 with it
Medium (default) · mainstream mid-range GPUs at 1080p
High · upper mid-range and high-end GPUs
Ultra · high-end GPUs

Requirements

• Minecraft Java 26.3 with Fabric
• Sodium 0.9.2+ and Iris 1.11.7+
• Graphics backend set to OpenGL (Video Settings). Iris does not run on Vulkan.

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.
