Iris Crash: Shadow Program Requested, But the Pack Does Not Have a Shadow Pass

What it looks like in the log

java.lang.IllegalStateException: Shadow program requested, but the pack does not have a shadow pass?

How to fix it

  1. Update Iris Shaders (or Oculus if playing on Forge) alongside Sodium (or Embeddium) to the latest release for your Minecraft version, as the Iris team fixed this dimension-switching bug in newer builds.
  2. If you are playing a locked modpack and cannot update Iris, press 'K' (default hotkey) or go to Video Settings -> Shader Packs to toggle shaders off before entering a portal, then turn them back on after arriving.
  3. Update your active shader pack to a newer version or test with a different shader pack to verify whether the pack's dimension files are broken.
