Frequently asked questions

What does the Hydrological Mod do to world generation?
It overhauls the overworld by generating massive continents and entirely new terrain layouts instead of endless random landmasses, creating a more structured world.
Where can you find unique ore placements in this mod?
Copper and gold veins spawn on Dripstone Cave walls, while iron and coal generate in Lush Caves, and diamond shafts appear just above bedrock.
What visual features make the environment feel more alive?
The mod adds glowing blocks like blue ice, fireflies that dance around tall grass at night, and custom temperature-based fog that changes color depending on your biome.
What special world presets does the mod offer?
The mod provides special presets that let you play on floating islands or floating caves for a unique survival experience.
What custom decorative blocks are included in the mod?
The mod adds custom blocks such as leaf piles, wood walls, dry grass, and mushroom slabs for decorating your builds.
How does the server-only mode work?
Server-only mode turns off custom blocks so that players can join a server without needing to download the mod themselves.
