About this project

What does No Worldgen Warning add?

While this warning may be useful for debugging, it becomes excessively verbose when using certain world generation data packs, flooding logs and making them hard to read. This mod simply disables that particular warning, keeping your log files clean without affecting world generation or gameplay in any way.

Features

✅ Removes only the targeted log spam, leaving all other logging intact.
✅ Works on both client and server – no gameplay changes.
✅ Compatible with any mod or data pack – just install and forget.

Technical Details

The mod uses Mixin to inject into the DensityFunctions.TwoArgumentSimpleFunction class and suppresses the warning conditionally. It is safe to add to existing worlds and requires no configuration.

Dependencies

For Minecraft 1.20.1 (Forge): Requires Mixin Booster or Sinytra Connector as a dependency.
Other versions (Fabric, NeoForge, or Forge for different Minecraft releases) do not need any additional dependencies.

Installation

Download the mod jar for your Minecraft version and mod loader.
Place it in your mods folder.
(Forge 1.20.1 only) Ensure Mixin Booster is also installed.
Launch the game – the warnings will be gone!

No Worldgen Warning – keep your logs clean, your mind at ease.
