TheMaxFPS Shader

Realistic Vibes brings Minecraft's vanilla world to life with grounded, natural lighting instead of flat block shading. Sunlight and moonlight cast soft, filtered shadows across the terrain; water rolls with gentle waves and reflects the sky and sun with a realistic fresnel effect; grass, flowers, and vines sway in the wind. Torches and other light sources flicker gently instead of sitting at one flat brightness, lava throbs with a slow emissive pulse, and patchy cloud shadows drift across the ground as if clouds were passing overhead. Rain darkens and dampens exposed ground, diving underwater tints and dims your view, and volumetric light shafts beam through gaps in trees and mountains at sunrise and sunset. A filmic color grade (ACES-style tone mapping, boosted saturation, subtle vignette) ties it all together for a "real camera" look, while distance fog blends smoothly into the sky.

Built to be readable and easy to extend — every shader file is plain, commented GLSL following the standard OptiFine/Iris pipeline.

Features:

• Dynamic sun/moon directional lighting
• Soft, slope-aware shadow mapping (no acne, no peter-panning)
• Waving, reflective water with sun/moon glint
• Wind-swaying grass, flowers, and vines
• Torch flicker on block-lit surfaces
• Pulsing emissive lava glow
• Animated, drifting cloud shadows
• Rain wetness on exposed ground (skips indoor/cave areas)
• Underwater color grading
• Volumetric light shafts (god rays)
• Bloom on bright light sources
• Filmic tone mapping, saturation boost, and vignette
• Distance fog that blends into sky color

Compatibility: OptiFine or Iris (Fabric/Sodium), Minecraft Java Edition.
