Wrong Minecraft version

NoClassDefFoundError: Sodium VertexBufferWriter Missing

What the log looks like

java\.lang\.noclassdeffounderror:\s*me/jellysquid/mods/sodium/client/render/vertex/vertexbufferwriter

How to fix it

  1. Update Physics Mod (or Physics Mod Pro) to the latest release built for your Minecraft version (for example, version 2.12.4 or newer on Minecraft 1.19.4).
  2. Update all other Sodium addons and rendering mods in your mods folder—especially Indium and Iris Shaders—to versions explicitly marked compatible with your installed Sodium version.
  3. If you are using an older mod or Physics Mod Pro build that has not been updated for your Sodium version, downgrade Sodium (e.g., from 0.4.11 down to 0.4.10 on 1.19.4) and downgrade Indium (e.g., to 1.0.15) so their versions align.
