Description from the author on Modrinth

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)

How to install Ultra Realistic PBR Shader Pack

  1. Install Iris (with Sodium) or OptiFine for your Minecraft version: shaders need one of them.

  2. Download the .zip file from Modrinth. Do not unzip it.

  3. In Minecraft, open Options, then Video Settings, then Shader Packs, and click Open Shader Pack Folder.

  4. Drop the .zip file into that folder, pick Ultra Realistic PBR Shader Pack in the list and click Done.

  5. Shaders are heavy on the graphics card. If the game gets slow, pick a lower profile in the shader settings.
