Iris Shaders in FTB StoneBlock 4

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.

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]

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.

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]

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 StoneBlock 4's own recipes, read from the pack itself: look the item up in the item browser.

FTB StoneBlock 4 1.21.0 ships Iris Shaders as a 1.8.14 beta build for Minecraft 1.21.1. Iris was first included in FTB StoneBlock 4 1.0.0 or earlier, so it is not a recent addition.^[3]

Mod changelog highlights

• The 1.8.14 beta build, the one in the pack now: updates to Sodium 0.8 and fixes a few old bugs. The changelog does not say which bugs.^[3][4]
• 1.8.12-snapshot+mc1.21.1-local: fixes support for Pixelmon. The sources do not show this build in the pack.^[3][5]

Unverified Which FTB StoneBlock 4 releases changed Iris, and when it moved to its current version, is not shown in the sources here, because they contain no pack changelog entries for this mod. Check the pack's own release changelogs for that.
