Description from the author on Modrinth

Phial

Phial is a work-in-progess shader that aims to add several post-processing options to mimic pixel art.

As of the latest version it has:

  • Color quantization to limit the screen colors to a arbitrary color palette. (defaults to the Ressurect 64 palette)
  • Customizable pixel mapping to lower the screen resolution
  • Ordered dithering
  • Customizable vignette

Custom Palettes

To input custom palettes, you can unzip the shader and locate the palette file at:
shaders\assets\palette.glsl

This requires a special format of storing colors, namely a vector 3 normalized GLSL array. To quickly convert a list of hex colors to this format, you can use the following site:

snorfield.github.io/palette-to-shader/

Once converted, you can simply open the palette.glsl file in a text editor such a notepad and replace the contents. Don't forget to save!

All you need to do to see the changes is reload the shader.

How to install Phial

  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 Phial 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.
