Does it go on the server or on players' games?

Iris Shaders is a client-only mod: it doesn't run on the server. Each player installs it in their own Minecraft if they want it. Add it in the panel as "Players only" and it ships inside everyone's modpack.

How to add Iris Shaders to your server

  1. Open the panel and create a world with a compatible loader and Minecraft version (Fabric and NeoForge, per the table above), or open one you already have.
  2. In the world's "Mods" section, search for Iris Shaders in the Modrinth catalog. You'll only see what works with your world.
  3. Add it with the "Players only" option, the one the panel suggests for this mod.
  4. Start or restart the server so it installs along with its dependencies.
  5. Ask your friends to download the .mrpack modpack from the panel again.
