Principal Shaders (26.2, 1.20.1) – Volumetric Clouds and Reactive Weather

August 8, 2026

Principal transforms lighting in your Minecraft world while keeping the classic vanilla style. This shader pack adds volumetric clouds that float across the sky and reactive weather that changes how blocks look during rain. It gives the game a realistic feel without changing the blocky shapes you know.

Features:

Adds thick volumetric clouds that drift across the sky instead of flat textures.
Changes the lighting based on the weather, making storms look darker and rain feel wetter.
Paints cinematic skies during different times of the day.
Keeps the original vanilla feel of the game while upgrading the shadows and light rays.
Casts realistic shadows from blocks, trees, and buildings across the ground.
