World Generation & Dimensions

World generation mods rewrite what the game builds before you ever place a block, so they matter most on a brand new save. Some add biomes and trees, some reshape terrain into taller mountains and deeper canyons, some rework caves or where ore actually spawns. The larger ones add entire dimensions with their own skies, mobs and materials, or overhaul the Nether and the End instead of leaving them half finished.
