Zarya is a fork of minecraft-miniature-shader by Mateus A. Kreuch, with a large visual extension layer added by Throw New Error.

What's new in Zarya

• Volumetric lighting — god rays with weather and rain interaction
• Atmospheric fog — height fog, Mie-style scattering, Nether fog, weather blending
• Procedural clouds — three-layer cloud model (low / mid / upper), cloud shadows
• Temporal anti-aliasing (TAA) — Catmull-Rom history sampler, YCoCg color clipping
• FXAA + sharpen — fast edge AA with configurable sharpness recovery
• SSAO — screen-space ambient occlusion
• Procedural normals — generated from albedo at runtime, no resource pack needed
• IPBR — specular, emission and normals driven by image analysis
• Procedural stars — twinkle, color temperature, density control
• Waving foliage — leaves and tall plants with snow / rain amplitude modulation
• Distant Horizons/Voxy support — LOD seam dithering, shadow pass, lod water
