Solved Chunk Generation

Hi, I am working on a custom chunk generator and basically, I want to add vanilla cave generation to my world and in the docs it says you can override shouldGenerateCaves() to enable it. So I put this in my code and neither structures nor caves generate, can anybody help me out here's what I put in my chunk generator class:

Code:

@Override
    public boolean shouldGenerateCaves() {
        return true;
    }
    @Override
    public boolean shouldGenerateStructures() {
        return true;
    }

Also is there any way I could implement custom structures from a file, like a structure file that Minecraft uses with structure blocks in-game to make my life easier for modifying the structures, is the only way to achieve this by creating the structure in the code? Or is there a way to use a file?

 

Do you have this override in your main class?

PHP:

@Override
public ChunkGenerator getDefaultWorldGenerator(String worldName, String id) {
    return new CustomChunkGenerator();
}

 

Yes

EDIT: Nvm I guess seems that you cannot have caves generate using that method if you do not fill your entire underground with stone, specifically stone.
