Stone Block Generation

I build this mod, because I liked playing in stoneblock packs.
This one uses the premise that was introduced in Stoneblock 3 and 4 where you have stone, then nether, then end. 

A complete StoneBlock-style world generation mod for NeoForge 1.21.1

Built to match the world profile used by StoneBlock 3 and StoneBlock 4, Stone World Generation replaces the standard overworld with a fully solid stone world — no sky, no surface, just rock in every direction. Designed to drop into any modpack that wants that StoneBlock feel without being locked into a specific pack.

What It Does

Instead of the normal overworld, you spawn inside a solid stone world divided into concentric biome rings that radiate outward from the center. Each ring transitions smoothly into the next using custom blend biomes, creating a natural progression from safe starter area out into increasingly dangerous territory.

Features

World Generation

• Fully solid stone world — no caves, no sky, no void bedrock issues
• Custom noise settings for a perfectly flat, seamless stone fill
• Lava sea layer in the Nether region from bedrock up to -40y.
• Compateability with other ores that generate ore/stones.

Ores

Each biome ring has its own ore set placed at appropriate depths and densities:

• Stone zone: Coal, Iron, Copper, Lapis, Andesite, Diorite, Granite, Amethyst
• Deepslate zone: Iron, Gold, Lapis, Redstone, Diamond, Emerald
• Nether zone: Nether Quartz, Nether Gold
• Eternal/Deep Dark zone: Ancient Debris

Structures

• Trial Chambers — fully enabled with custom loot tables tuned for StoneBlock progression. Normal and Ominous variants both supported with unique, rare, and common reward tiers
• Mineshafts — enabled across appropriate biome rings
• Monster Rooms — enabled for dungeon crawling
• Dungeon Crawl (optional) — biome mappings included for compatible dungeon generation if Dungeon Crawl mod is present

Spawn Room

• Custom spawn room generated at world origin in the Stone Safe zone
• Gives new players a safe foothold before venturing into the stone

Loot Tables

All Trial Chamber loot tables are customized — more progression-appropriate rewards including enchanted books, diamonds, gold, iron, wind charges, and experience bottles. Ominous vaults scale up with better gear and higher diamond/emerald counts.

Compatibility

• NeoForge 1.21.1 — required
• Dungeon Crawl, Apotheosis,Not Enough Trials / Hellish Trials 
• Designed for use in modpacks — no hard dependencies beyond NeoForge and Minecraft

Installation

Drop the JAR into your mods folder. No configuration required. Works best as part of a StoneBlock-style modpack where the overworld is expected to be a stone void.

This mod replaces the overworld dimension. Do not use in a world where you want a normal overworld to exist alongside it.
