This datapack changes the terrain shape in lowland biomes (eg. Plains, Forests etc). This is done by editing the 'offset' and 'factor' density functions, making it incompatible with any other pack or mod that changes either of these files.
Edits to 'offset' lower the base height in these areas. Edits to 'factor' reduce areas of pronounced bumpiness, as well as make areas such as Windswept Savanna less extreme. Mountain biomes are unaffected. Full list of changes in info.txt.
