About

This mod replaces vanilla world generation with more realistic, continuous terrain — smooth biome transitions, natural coastlines, and rolling landscapes. Building on the original mod (whose oceans were unfinished and never actually generated — in fact, you can't find any ocean in GTNH), it delivers a complete ocean overhaul. Centered on the ocean theme, it adds a matching set of biomes, terrain, and structures, so the sea is no longer an empty blue void but a living part of the world.

This mod is a drop-in replacement for the RWG mod in GTNH. (Use caution with existing saves.)
