Details
FloodWorld is a Fabric mod that replaces all air with water during chunk generation.

- Fully configurable (ModMenu + Cloth Config)
- Cave flooding by default
- Server compatible, Works on multiplayer servers. Clients do not need the mod installed.

Configuration
Requires ModMenu and Cloth Config for in-game configuration
Replace Air - Fills regular air blocks with water
Replace Cave Air -Fills cave air blocks with water
Max Water Height - The Y level below which air becomes water
Native Flooding - Places water during generation (fast) vs post-processing tick queue (compatible)

Dependencies
Required:
- Fabric Loader
- Fabric API
Optional (for config screen):
- ModMenu
- Cloth Config

Minecraft 1.21.x (Fabric) Should work on fabric multiplayer servers, server-side only, no client installation required

Settings only apply to newly generated chunks. Existing chunks will not be retroactively flooded or un-flooded. On first world creation there may be a brief loading screen delay while Minecraft locates a valid spawn point above the waterline. Changing the Native Flooding setting requires a world restart to take effect on new chunks.
