I want to create a Custom Biome Provider which only generate my custom biomes, i tried a lot with overiding the Vanilla Biomeprovider and looked in the class how it works but that always only caused a crash, i tried creating a Gen Layer but the problem there is the rivers and Oceans still spawn, i want a completly Vanilla Bilme Free world, no rivers, no ocean, only my biomes, how is this possible and what i need to know to override the Provider?
