About
Ultra Realistic PBR v1.0
A next-generation physically based rendering shader pack engineered for astronomical accuracy, planetary-scale optics, and atmospheric realism in Minecraft.
Features
- Astronomical Sky (Overworld & Deep Space): True 23.5° axial tilt sidereal rotation and Milky Way dust absorption lanes.
- Deep-Space Planetary Mechanics (The End): The End serves as an exo-atmospheric observation vantage point, resolving photorealistic dynamic solar system planets (Venus, Jupiter, Mars, Saturn) alongside the Apollo 17 Earth.
- Apollo 17 Earth: Photorealistic rotating "Blue Marble" Earth in The End dimension, featuring continental geography, dynamic cyclone cloud systems, specular ocean glints, polar ice caps, and night-side city lights.
- Fluid Optics: Translucent water absorption driven by Beer-Lambert law and Fresnel equations, combined with multi-frequency domain-warped waves.
- Weather & SSR: Rain accumulation causes porous surface darkening and real-time Screen-Space Reflections (SSR) across wet blocks and puddles.
- Soft Shadows: 12-Tap Poisson disk filtering with slope-scale and distance-adaptive depth biasing to eliminate shadow acne and Peter Panning.
- Color Science: ACEScg filmic tone mapping with dark-adapted scotopic vision (Purkinje effect).
- Dimension Safety: Native multi-dimension pipeline isolation (
world0,world1,world-1) guaranteeing crash-free cross-dimension travel.
Requirements
- Minecraft Version: 1.16.5 – 1.21+
- Shader Loaders: Iris Shaders / Oculus + Sodium
- Hardware: OpenGL 4.5+ compatible GPU (NVIDIA GTX 1660 / RTX 3060 / RTX 4060+ or AMD equivalent)
