I tried to make a world generation, but results are really weird.

what did you mean by 'really weird'

I mean, everything is void, and also, every structure from every dimension generated in overworld. For example, Nether structures generated in overworld.

when you do what, since you haven't so much world generation stuff?

@Luis_ST OK, the void isn't weird, but, the Nether structures in overworld is really weird, and I want to fix that.

that is your error, use the other constructor for the DimensionStructuresSettings
for the StructureMap you can take a look at the Default Map in DimensionStructuresSettings.DEFAULTS

I did that, but nothing happened:

package com.kg.kgforge.factory;

import java.util.Optional;
import net.minecraft.util.registry.Registry;
import net.minecraft.world.biome.Biome;
import net.minecraft.world.gen.ChunkGenerator;
import net.minecraft.world.gen.DimensionSettings;
import net.minecraft.world.gen.FlatChunkGenerator;
import net.minecraft.world.gen.FlatGenerationSettings;
import net.minecraft.world.gen.settings.DimensionStructuresSettings;
import net.minecraftforge.common.world.ForgeWorldType;

public class KGFactory implements ForgeWorldType.IChunkGeneratorFactory {
    @Override
    public ChunkGenerator createChunkGenerator(Registry<Biome> biomeRegistry, Registry<DimensionSettings> dimensionSettingsRegistry, long seed, String generatorSettings) {
        return new FlatChunkGenerator(new FlatGenerationSettings(new DimensionStructuresSettings(Optional.empty(), DimensionStructuresSettings.DEFAULTS), biomeRegistry));
    }
}

now you do exactly, what the first constructor does
in other word you haven't changed anything

take a look at the DimensionStructuresSettings#DEFAULTS copy the logic,
and do the same thing for the Structures you want to spawn

Then, modded structures will not work anymore.

then copy the DimensionStructuresSettings#DEFAULTS into a new Map,
then remove the Structures which shouldn't generate and then use this Map in your DimensionStructuresSettings
