Eternal Prism الشيدرات لماينكرافت 1.21.1, 1.21

Eternal Prism

A cinematic Iris shader that makes Minecraft feel alive — volumetric light, 3D clouds, living water and a night sky worth staring at. Scales from low-end PCs to cinematic ultra.

Features

Light & Atmosphere

• Volumetric light — real light shafts through trees and terrain
• Soft shadows (PCSS) — shadows blur naturally with distance
• Two-tone lighting — warm sunlight, cool sky ambient
• Height-based ground fog — morning mist settles in valleys
• Aerial perspective — distant terrain fades into the sky

Sky

• Volumetric 3D clouds with self-shadowing (SUPER_HIGH/ULTRA)
• Milky Way, nebulae and twinkling stars at night
• Aurora borealis — procedural, different every night
• Golden sunsets with time-of-day color grading

Water

• Gerstner waves — physically-shaped, animated
• Screen-space reflections — water mirrors the world
• Caustics, foam and subtle rainbow iridescence (it is a prism, after all)

World

• Swaying foliage — leaves, grass and flowers react to wind
• Wet surfaces in rain — blocks darken and shine
• Cinematic post-processing — bloom, DoF, film grain, ACES tone mapping

Fully customizable — 26 options

Toggle every effect individually and tune brightness, saturation, contrast, wave height, fog density and more — right from Shader Options. No reinstall needed.
