Silva Pro
Silva Pro is a lightweight Minecraft shaderpack designed to deliver modern, atmospheric visuals without demanding high-end hardware.
The shader focuses on realistic lighting, soft shadows, natural atmospheric scattering, improved water, procedural clouds, cinematic post-processing, and smooth performance across low-end, integrated, and mid-range GPUs.
Silva Pro uses an optimized GLSL 1.20 pipeline compatible with Iris and OptiFine, keeping the shader accessible to older hardware while still offering higher-quality rendering options for more powerful systems.

- Animated foliage, crops, vines, fire, and lava
- Wind gusts and weather-reactive vegetation
- Separate lighting behaviour for the Overworld, Nether, and End
- Optimized for Iris and OptiFine
Performance
Silva Pro is built around scalable rendering.
Lower quality levels reduce expensive shader operations such as shadow samples, SSAO samples, SSR steps, cloud detail, and atmosphere integration. Higher quality levels progressively increase visual fidelity for hardware with additional GPU headroom.
This allows Silva Pro to provide a good visual upgrade even on integrated graphics while still offering advanced rendering features for stronger systems.
Compatibility
- Iris
- OptiFine
- GLSL 1.20 / OpenGL 2.1+
- Minecraft 1.16+ through modern versions

## 📦 Compatibility
Silva Pro reaches its first stable Long-Term Support release with major improvements across lighting, atmosphere, shadows, bloom, post-processing, and performance scaling.
## 🌤️ Sky & Atmosphere
- Replaced the old gradient sky with analytic Mie + Rayleigh atmospheric scattering.
- More natural blue skies at noon and orange/red sunrise and sunset tones.
- Added quality-scaled atmosphere rendering for low-end to high-end hardware.
- Improved sun appearance with a realistic corona ring and horizon reddening.
- Reworked clouds with layered procedural detail and improved depth.
- Improved stars with multi-frequency twinkling, colour variation, and rare brighter stars.
## 💡 Lighting
- Upgraded to full Cook-Torrance specular lighting using GGX, Smith geometry, and Schlick Fresnel.
- Improved metallic surfaces with colour-tinted specular highlights.
- Added improved foliage subsurface scattering for more natural leaves.
- Added multi-bounce ambient lighting to brighten dark undersides naturally.
- Improved torch and lantern light falloff.
- Improved handheld lighting transitions.
## 🌑 Shadows & Ambient Occlusion
- Improved soft shadows with more stable PCSS blocker sampling.
- Smoother contact-shadow transitions and better shadow bias handling.
- Improved coloured shadows through water and stained glass.
- Upgraded SSAO with cosine-weighted sampling and improved falloff.
- Reduced unwanted SSAO halos on flat surfaces.
## ✨ Bloom & Post Processing
- Reworked bloom using Dual-Kawase filtering for a smoother circular glow.
- Added a 13-tap bloom prefilter to reduce bright-pixel artifacts.
- Added subtle adjustable lens-dirt effects.
- Added AgX tone mapping for better handling of bright skies and dark caves.
- Upgraded FXAA to a higher-quality 9-tap implementation with Sobel edge detection.
- Replaced the old sharpening method with AMD CAS adaptive sharpening.
- Improved dithering to reduce visible colour banding.
- Improved underwater distortion, night vision, and lava vision effects.
## 🌊 Water
- Improved water rendering and depth-based absorption.
- Improved ripple normals and surface detail.
- Refraction, Fresnel reflections, and underwater effects remain available.
- Screen-space reflections remain optional for players who want higher visual quality.
## ⚙️ Quality & Performance
- Added automatic quality scaling for shadows, SSAO, SSR, clouds, and atmospheric rendering.
- Low-quality settings reduce expensive sampling for integrated GPUs.
- Higher presets automatically increase rendering quality when more GPU power is available.
- Continued optimization of water, shadows, and fullscreen effects.
## 🌎 Dimensions
- Continued separate rendering behaviour for the Overworld, Nether, and End.
- Improved atmospheric and lighting handling across dimensions.
## 📦 Compatibility
- Maintains the legacy GLSL 1.20 pipeline for broad hardware compatibility.
- Optimized for Iris and OptiFine.
- Designed to remain lightweight while providing a significant visual upgrade over vanilla Minecraft.
- Silva Pro v1.0.0 is now a stable LTS release.**
