William Wythers’ Overhauled Overworld Data Pack (1.21.10, 1.20.1) is a comprehensive Minecraft data pack that meticulously transforms the vanilla overworld into a visually stunning and immersive landscape. Without relying on mods, this data pack breathes new life into your Minecraft world, creating a more cohesive, atmospheric, and picturesque experience. Enjoy playing this data pack!

Features:
- Adds many sub-variants to biomes, as well as unique and rare transition regions where various biomes meet.
- Trees of all shapes and sizes fill the world.
- Stony cliffs and scree escarpments are common in the highlands.
- Ore blobs (diorite, andesite and granite) no longer pollute the clean grey of stone cliffs. Instead, these ores are found in abundance in their own allocated places.
- Diorite is readily available in the Flower Forest, granite in the Sunflower Plains and Birch Forest, and andesite in the Meadow and Cherry Grove.
- Lava lakes and springs are no longer to be found in the surface of overworld biomes, except for the volcanic Stony Peaks and Windswept Hills biomes.
