Iris Crash: Missing sampler Sampler1 in GlCommandEncoder.trySetup

What it looks like in the log

java.lang.IllegalStateException: Missing sampler Sampler1`, thrown from `GlCommandEncoder.trySetup` (line <so> on this build), reached via `GlRenderPa

How to fix it

  1. Update Iris Shaders and Sodium to the newest release for Minecraft 26.1+ to get the fix for PBR sampler validation (tracked as Iris issue #3137).
  2. If no fixed Iris version is available yet, open Options -> Video Settings -> Shader Packs -> Shader Pack Settings and disable PBR, Integrated PBR, Normal Maps, and Specular Maps.
  3. If the game crashes before you can reach the menu, edit your active shader pack's .txt configuration file inside the shaderpacks folder to turn off PBR features, or switch to a non-PBR shader pack.
