Cozy Autumn – Warm Cinematic Shader

Cozy Autumn is a complete lighting overhaul that discards Minecraft's flat, uniform illumination in favor of a cinematic, physically inspired renderer. Rather than simply tweaking brightness, it rebuilds how light behaves: sunrises and sunsets glow with genuine radiance, shadows gain depth and softness, and water reflects the world with true specular highlights. This shader solves the problem of lifeless, flat scenes by injecting a painterly autumnal mood—warm golds, amber horizons, and deep rust tones—while still preserving enough visibility for building, exploring, and combat.

It is built for players who treat visuals as part of the storytelling, from builders capturing their latest medieval village to survival players who want a cozier, seasonal atmosphere. Content creators and screenshot artists will appreciate the cinematic HDR tonemapping and dynamic sky, while anyone running a mid-range or high-end GPU can enjoy playable framerates. The shader leans into autumn's soft light rather than cold realism, so expect exaggerated warm tones during golden hour that may not suit every biome.

• HDR Tone Mapping: Applies an ACES Filmic curve to compress bright highlights without clipping, maintaining detail in sun-lit surfaces and deep contrast in shaded areas.
• Dynamic Atmosphere: Custom Rayleigh scattering controls time-of-day color transitions, paired with exponential depth fog and procedural volumetric clouds that drift and layer naturally.
• Advanced Water Rendering: Ray-marched Screen-Space Reflections (SSR) with sky-environment fallbacks and Fresnel intensity for rippling lakes and rivers that mirror the surroundings realistically.
• Autumnal Color Grading: A seasonal LUT shifts hues toward warm oranges, amber highlights, and muted greens, reinforcing the cozy feel particularly during morning and evening hours.
• Soft Shadow Cascades: Variable penumbra shadows that create natural, deep umbra under trees and structures, with contact hardening near the occluder for subtle, realistic shading.

Requirements: Cozy Autumn demands a dedicated GPU with OpenGL 4.3 or Vulkan support. You will need Iris Shaders or OptiFine (1.16.5 or newer) to run the pack. Performance is significantly heavier than vanilla; a mid-range card like an RTX 2060 or RX 5600 XT is the minimum for stable 60 fps at 1080p. Playing on integrated graphics is not practical. Some features, such as volumetric clouds, can be toggled in shader settings to reclaim performance.
