Basic Smooth WorldGen Datapack
by McMarmaj
Basic Smooth WorldGen Datapack is a data pack that adds biome variants to the world, including plains with flowers, colder plains with pumpkins and a jungle with savanna-style trees.
What it does
The data pack changes how the world generates. Plains get a variant rich in flowers, typically found around the lower meadow areas. A colder plains variant mixes a cold taiga look with meadow-like amounts of blue and white flowers, and another colder plains variant contains many pumpkins, some carved as jack o'lanterns, alongside yellow and orange flowers. A cold forest variant blends the normal dark forest with an autumn-like appearance.
The pack also adds a mountain variant resembling the pale garden, a plains variant with cherry grove terrain, smaller trees and more flowers, and a shore version of the swamp with tall grass and higher bog spawn rates. A jungle biome takes on savanna-like trees, a moss ground and a higher concentration of trees. Server owners install it as a data pack, and the server requires it while the client may leave it out. Files cover 1.20.1 – 1.21.8 across Fabric, Forge, NeoForge and Quilt, and snapshot builds are published.
