I've been doing Code (Text): ChunkGenerator vanillaGenerator = super.getDefaultWorldGenerator("world", ""); to get an instance of vanilla's ChunkGenerator but it seems to return null. How am I supposed to get it? And if you wonder why I need it, well, I want to add my own custom BlockPopulator, but to do so I need to override the function getDefaultPopulators inside of a custom ChunkGenerator class that i created. The problem is, as soon as I create that custom ChunkGenerator class to register my new populators, all the code of chunk generation is lost and my world is just void. I need to code myself the whole chunk generation in there. So I wanted to get an instance of the vanilla ChunkGenerator to pass it to my custom ChunkGenerator class and just use its generation.
