# Amplified world generation without excessive flooded caves
|
|
|
|
This datapack changes Minecraft's noise parameters to remove flooded caves in amplified world generation.
|
|
It achieves this by increasing the terrain density (= more stone/dirt) around y=46,
|
|
which cuts off most surface water from the cave systems.
|
|
It shouldn't make it harder to find caves since some seemingly ignore the inital density generation.
|
|
|
|
## Installation
|
|
|
|
Download the [.zip](https://github.com/FliegendeWurst/amplified_fixed/releases/download/v1/amplified_fixed.zip) and save it in your datapacks directory.

As you can see, some flooding near the surface remains. I believe that can be corrected by tweaking the y level of my fix, but that will also lead to more terrain changes.

## Removing all flooded caves
|
|
|
|
It is also possible to remove normal flooded caves by decreasing the `fluid_level_floodedness` noise.
