Description
Ecospherical Expansion is a mod aimed towards recreating biomes with more diversity and aesthetically pleasing scenes. Additionally, this mod adds custom integration with the Large Biomes and Amplified world presets; While also adding 8 new world presets to choose from.
NEWER VERSIONS (1.21+):
This mod will not be updated anymore, it has been replaced by my newer mod Hydrological (Overworld Terrain & Biomes) - Minecraft Mods - CurseForge

NOTE: Versions below 1.20.x do not have world presets. In those versions, this mod simply redoes the vanilla biomes.
Default:
- Terrain above the surface is the same as vanilla.
- Caves are now much more open.
- Oceans now lead into sprawling cave systems.

- Biomes are much larger.

Amplified:

- World height has been extended to Y512.
- Terrain has been reworked to add massive variation in style across large distances.
- There are now small floating islands that generate above the existing terrain.
