[SOLVED] How do I remove default biome generation for custom biome

[Xoroshio]

Hi there, how do i remove the default generation? My biome generates very default things such as caves, dirt, water, and grass.

How do I make it only generate features? For example, the biome would be void with some floating custom features.

ok, i solved it by using a FlatLevelSource chunk generator and having no layers. i also called setDecoration();
