Stoneblock

To create a Stoneblock-like modpack, you can simply set the surface settings as shown in the configuration below.

config/skyblockbuilder/world.json5
{
  "surface": true,
  "surfaceSettings": {
    "minecraft:overworld": "minecraft:bedrock,382*minecraft:stone,minecraft:bedrock",
    "minecraft:the_nether": "",
    "minecraft:the_end": ""
  }
}

The downloaded file also sets the default world type to Skyblock, generating Bedrock at the top and bottom of the dimension. There is only one spawn point, and a starting inventory is included, as shown below: Starting item

config/skyblockbuilder/starter_inventory.json5
{
  "items": [
    {
      "item": "minecraft:wooden_pickaxe",
      "nbt": "{Damage:0,Enchantments:[{id:\"minecraft:efficiency\",lvl:2}],Unbreakable:1b,display:{Name:'{\"text\":\"Infinite Pickaxe\"}'}}"
    }
  ]
}
