Amplified world generation without excessive flooded caves

This datapack changes the 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 and copy into your datapacks directory.

Removing all flooded caves

It is also possible to remove normal flooded caves by decreasing the fluid_level_floodedness noise.
