Description from the author on Modrinth

Samarium Shaders is a lightweight yet visually stunning custom Minecraft shader pack designed for Fabric (supporting Minecraft 1.21.11 and 26.2). Built to merge high-end visual realism with performance optimization, Samarium Shaders completely transforms your Minecraft world into an immersive, atmospheric experience.

✨ Key Features:
Raymarched Volumetric Clouds: Dynamic, 3D procedural clouds that drift across the sky with realistic density, self-shadowing, and atmospheric depth.
Rayleigh & Mie Atmospheric Scattering: Breathtaking sky colors, realistic horizon fades, and gorgeous golden-hour sunsets.
Real-Time Soft Shadows: Crisp, optimized sun-perspective shadows utilizing 3x3 Percentage-Closer Filtering (PCF) and shadow-map distortion for clear close-up details.
Realistic Water Physics: Multi-layered procedural wave displacement, Schlick’s Fresnel reflections that mimic real-world water surfaces, and shimmering sun specular highlights.
Living World Animation: Subtle wind-waving effects injected into leaves, tall grass, crops, and modern flora.
ACESS Filmic Tonemapping: Rich contrast, natural lighting exposure, and cinematic post-processing depth.

🎛️ Fully Customizable In-Game Menu:
No need to touch code to tweak your experience! Open the Shader Options menu right inside Minecraft to adjust:
Quick Performance Profiles: Instantly switch between Low (Performance), Medium (Balanced), and Ultra (Cinematic) presets.
Cloud & Shadow Quality: Scale your raymarching steps and shadow resolutions on the fly.
Atmosphere Controls: Fine-tune camera exposure, sunlight bloom intensity, and cloud coverage.

How to install Samarium Shaders

  1. Install Iris (with Sodium) or OptiFine for your Minecraft version: shaders need one of them.

  2. Download the .zip file from Modrinth. Do not unzip it.

  3. In Minecraft, open Options, then Video Settings, then Shader Packs, and click Open Shader Pack Folder.

  4. Drop the .zip file into that folder, pick Samarium Shaders in the list and click Done.

  5. Shaders are heavy on the graphics card. If the game gets slow, pick a lower profile in the shader settings.
