What is Iris Shaders?

3 parts

Same as in the All the Mods 10 8.1 guide

Iris is a shader pack loader for Minecraft. It is meant to be compatible with existing OptiFine shader packs, so you can load the shaders you already know and change how the game looks.[1]

What this pack ships

The pack includes the NeoForge build of Iris Shaders, version 1.8.14 (a beta release). It has been in the pack since version 2.25 or earlier.[2]

Getting shaders to use with it

Iris only loads shader packs, so you need to download one yourself. The shaders section on Modrinth is the place to browse.[1]

Iris supports almost all shader packs. The project keeps a list of unsupported shader packs and a list of unfixable limitations, so check those if a shader misbehaves.[1]

Where it sits in the quest book

Unverified The sources here do not show any quest chapter, group or position for Iris, and they do not show whether the ATM Star path uses it.

How do you get started with Iris Shaders?

2 parts

Same as in the All the Mods 10 8.1 guide

Iris is a shader pack loader. It is built to work with existing OptiFine shader packs, so the mod itself is only half the setup: you also need a shader pack to load.[1]

Your first steps

  1. Find a shader pack. The shaders section on Modrinth is the place the Iris project points you to for browsing them.[1]
  2. Read the installation guide on the Iris project's documentation. It is the official walkthrough for getting set up.[1]
  3. Check the list of unsupported shader packs before you download one. Iris supports almost all shader packs, but a few don't work.[1]
  4. Skim the list of unfixable limitations in Iris, so you know what to expect if something looks off.[1]
Tip: If something goes wrong, the Iris FAQ page is the first place to look. The Iris Discord server is also where you can chat about the mod and get support.[1]

Anything to craft?

Unverified We couldn't confirm any in-pack recipes, items or quests for Iris, so there is nothing to craft or unlock here. Treat it as a client-side setup step rather than a progression step.

How does Iris Shaders work?

2 parts

Same as in the All the Mods 10 8.1 guide

Good news for your automation plans: there's nothing to wire up here. Iris Shaders is described as a modern shader pack loader for Minecraft, built to be compatible with existing OptiFine shader packs. It's a visual mod, and the source material doesn't describe any machines, multiblocks, power, fluids or item handling.[1]

What Iris actually does

Iris loads shader packs and applies them to the game's visuals. The shader packs themselves are separate downloads, and the project points you to the shaders section of Modrinth to find them.[1]

Compatibility and limits

Iris supports almost all shader packs, but not every one. The project keeps a list of unsupported shader packs and a separate list of unfixable limitations. Check both if a shader pack looks broken or won't load.[1]

Tip: If a shader pack misbehaves, look at the project's FAQ, its unsupported shader packs list and its limitations list before assuming something is wrong with your install.[1]

Unverified This pack's specific Iris settings, default shader pack, keybinds and any pack-specific changes could not be confirmed from the available sources. No config files, recipes, quests or in-game descriptions for Iris were provided. This site does hold FTB Skies 2: Aero's own recipes, read from the pack itself: look the item up in the item browser.

What changed in Iris Shaders between versions?

2 parts

There isn't much version history to tell for Iris Shaders in this pack. FTB Skies 2: Aero 1.10.0 ships a beta build of Iris Shaders numbered 1.8.14, and the mod was already in the pack by FTB Skies 2: Aero 1.0.3 or earlier.[3]

Current version

The mod's own changelog for this 1.8.14 beta build is short: it updates to Sodium 0.8 and fixes a few old bugs. It doesn't say which bugs were fixed, so there's nothing more to tell you there.[4]

Pack changelogs

Unverified The pack's own release changelogs are where any change to this mod between pack versions would be recorded. The sources here contain no pack changelog entries for Iris Shaders, so how its version changed across pack releases, or whether the pack altered anything about it, is not shown.

Items and blocks

We can't match this mod to the pack's item list: it registers as iris, and the pack's recipe dump has nothing under that name. That means we found nothing, not that the mod adds nothing. Search the item browser
