Resource packsIris Shaders Error: Framebuffer must have at least one color buffer
What it looks like in the log
java.lang.IllegalArgumentException: Framebuffer must have at least one color buffer
How to fix it
- Press Esc in-game, go to Options > Video Settings > Shader Packs, and switch to an Iris-compatible shader pack (such as Complementary, BSL, or newer releases of Chocapic13).
- Update Iris Shaders (or Oculus on Forge) and Sodium (or Embeddium) to the latest version available for your Minecraft version, as newer Iris releases include workarounds for legacy shaders.
- Update the shader pack itself if a newer version is available from the author on Modrinth or CurseForge.
- If you only experience this error in a specific dimension like The End, press 'K' (default Iris toggle hotkey) to temporarily turn off shaders while exploring that dimension.
