Description from the author on Modrinth

What is the UShader?

This shaderpack is a recreation of a modified version of SEUS v10.1 I used privately for a long time. Took me a while to match some of the unique looks the SEUS version had but I eventually figured it out.
Please note that this pack does not perform better than SEUS v10.1 with the default settings due to many new effects that didn't exist in that version, like volumetric clouds and fog. With the correct settings however it is able to outperform it by a lot while producing much better visuals.
It is also important to note that this pack does not use any code from SEUS v10.1.

What features does it offer?

  • atmospheric sky
  • volumetric fog
  • volumetric clouds
  • dynamic shadows
  • soft shadows
  • screen-space raytraced ambient occlusion (RTAO)
  • water volume
  • dimension support
  • wind effects
  • temporal anti-aliasing and upscaling (TAAU)
  • motionblur
  • bloom

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 is generally recommended though
  • Windows/Linux
  • DUE TO REPEATED ISSUE-REPORTS: Intel HD 5000 Graphics and older are NOT supported!

How to install UShader

  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 UShader 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.
