## 📢 "It doesn't work" — three checks before you comment

**1. Nothing changed in-game?** The #1 cause, by far: the pack isn't selected.

Shaders live in **Options → Video Settings → Shader Packs** — a screen Iris adds,

**not** the Resource Packs screen. Pick **Afterimage**, press Done, let it compile.

Not sure it's on? Search `latest.log` for `Using shaderpack` — that line is the truth.

**2. Crash or missing Shader Packs screen?** Version mismatch.

This pack needs **Minecraft 26.1.2 on NeoForge** with **Iris** and **Sodium** builds

labelled for 26.1.2 (Iris 1.11.3 / Sodium 0.9.1 at the time of writing). Iris has never

supported Forge — Forge won't work, and neither will older Minecraft versions.

Playing **She Remembers** on 1.21.1? Use the ECLIPSE pack the mod installs from chat —

that one matches your version.

**3. Looks wrong rather than broken?** Every effect has a dial with a plain-English

tooltip in **Shader Options** — shadows, fog, the Nether's darkness, the entire End sky.

Also: updating to a new pack version resets your dial changes (Iris keys settings to the

zip's filename). That's a fresh-tuned default, not a bug.

Known and documented: spider/enderman eyes don't glow with the pack on.

**Still broken after all three?** Comment with: your MC + Iris + Sodium versions,

an F2 screenshot, and any `[Iris]` or shader lines from `.minecraft/logs/latest.log`.

That's usually enough to fix it in one reply. 🌒
