Veridian A realistic shaderpack for Minecraft 1. 20. 1 and 1. 21. 1 (Fabric + Iris). One pack works on both versions.

Features - Atmospheric sky with Rayleigh/Mie scattering, sunrise/sunset warmth, and stars - Soft shadow mapping with PCF penumbra and colored shadows through stained glass/water - Volumetric raymarched clouds with self-shadowing - Animated water waves, shore foam, Fresnel reflections, and screen-space reflections (SSR) - Volumetric light (sun shafts / god rays) - SSAO, bloom, and tonemap options (ACES / Uchimura / Reinhard) - Colored lighting on placed light sources (torches, glowstone, etc.) - Held torch light - Distant Horizons support (terrain lighting, optional water) - All settings adjustable in-game via the Iris shader menu

Performance Medium to High impact on modern GPUs. Heaviest settings are cloud steps, SSR steps, volumetric light steps, SSAO samples, and shadow filter samples — these can be lowered for weaker hardware. Install 1. Minecraft 1. 20. 1 or 1. 21. 1 with Fabric + Iris (Sodium recommended) 2. For distant terrain, install Distant Horizons 3. Place the .zip in .minecraft/shaderpacks/ and select it in Options → Video → Shader Packs

Limitations - No labPBR resource-pack support — smoothness/metalness are constant per material type - SSR only reflects on-screen geometry (screen-space limitation) - Atmosphere is an analytic approximation, not a multi-scatter LUT
