Configurable Cobblegen

Configurable Cobblegen lets you control what lava and water generators produce. Keep the default vanilla cobblestone behavior, or add ores, blocks, and custom weighted outputs through a simple server config.

Built for NeoForge 1.21.1, this mod is designed for skyblock packs, progression packs, custom resource generation, and any setup where cobble generators should provide more than plain cobblestone.

Features

• Replaces vanilla lava-water cobblestone and stone generation with configurable weighted results.
• Keeps vanilla behavior by default with minecraft:cobblestone=100.
• Uses simple relative weights, so rare blocks stay rare and common blocks stay common.
• Supports any registered block id, including blocks from other mods when they are installed.
• Includes optional Create compatibility for drill-based cobblegen setups.
• Does not require Create to be installed.
• Falls back safely to cobblestone if the configured entries are invalid or empty.

Configuration

The server config contains a generation section:

Enabled Toggle

Use enabled to turn configurable generation on or off.

Weighted Blocks

Use generatedBlocks entries in this format:

namespace:block=weight

Example:

minecraft:cobblestone=100

minecraft:iron_ore=5

minecraft:gold_ore=2

Weights are relative. With the example above, cobblestone is the most common result, iron ore is uncommon, and gold ore is rarer than iron ore.

Create Compatibility

Configurable Cobblegen includes optional support for Create's optimized drill cobblegen behavior.

When Create is present, the mod hooks into Create's cobblegen optimization so drill-based generators can roll the configured weighted output instead of always returning the same vanilla block. Create is optional; the mod works normally without it.

Recommended For

• Skyblock modpacks
• Custom progression packs
• Ore generator setups
• Create-based cobble farms
• Servers that want config-driven resource generation
