Description from the author on Modrinth

What is the Kappa Shader?

A shaderpack that aims towards a realistic, but also authentic look. So it is not plainly using physically accurate vales and equations like many other packs do. Instead, while still using many accurate calculations, it is tweaked to reproduce what you could observe in nature, which usually goes beyond just having equations to describe most phenomenons.

What features does it offer?

  • Dynamic soft shadows
  • Screen-space path-tracing (SSPT)
  • Temporal Anti-Aliasing and Upscaling (TAAU)
  • Procedural realistic skybox with multiple cloud layers
  • Screen-space reflections and optional offscreen environment reflections (when enabling the reflection capture)
  • Volumetric fog
  • Random per-day and daytime driven weather parameters controlling clouds and fog
  • labPBR resourcepack support
  • Various optional lens effects such as depth of field, lens flares and vignette

and many, many more.

Any Requirements?

  • Optifine for 1.16 or newer/Iris 1.5.0 or newer
  • GTX 1050/RX 560 or similar/better (has to support OpenGL 4.0, something faster than those is recommended though)
  • Windows/Linux
  • DUE TO REPEATED ISSUE-REPORTS: Intel HD 5000 Graphics and older are NOT supported!

How to install Kappa Shader

  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 Kappa Shader 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.
