A minimalist, mod-compatible one-block-void world type for Forge 1.16.5./1.20.1
Start with nothing but a single block beneath your feet — and everything else is up to you.
Void One Block adds a brand-new world type to Minecraft. Instead of generating normal terrain, it strips everything away and leaves you standing on exactly one block, floating in the void. From there, it's your job to survive and expand — while biome identity still works exactly as it should, so modded biomes and biome-aware systems behave normally even though there's no terrain to look at.
No mountains. No oceans. No forests. No structures to stumble into. Just you, one block, and whatever you build from there.
The Overworld spawns you on a single platform block above an endless void. The block regenerates itself if it's ever removed by outside means (but never overwrites anything you've placed — it only fills in plain air).
Take the challenge further — the Nether and the End can be voided too:
Both are optional and configurable independently.
This void generator preserves original biome sources, so modded biomes (BYG, BOP, and similar) still assign their correct biome IDs to your world — useful for anything that keys off biome identity. Structures, however, are intentionally disabled across every void dimension: no strongholds, villages, fortresses, bastions, End Cities, or modded structures will generate. The one-block challenge is meant to be self-contained rather than a structure hunt.
Choose exactly what you start on. By default, Void One Block pairs with Random Item Generator Resurrected, spawning you on its mystery item block for an extra layer of unpredictability. Don't have that mod installed? No problem — it automatically falls back to plain minecraft:bedrock so the world always generates safely.
spawnBlock = "random_item_generator_resurrected:item_block"Enabled the bonus chest at world creation? It'll spawn right beside your starting block, using the standard vanilla loot table — one time only, and it won't reappear once it's been placed.
End gateways get a small safety platform automatically, so stepping through one in a void End won't strand you in empty space.
World generation settings are marked stable, so you won't get the "This world uses experimental settings" pop-up when creating a Void One Block world.
| Option | Default | Description |
|---|---|---|
spawnBlock |
random_item_generator_resurrected:item_block |
The block placed beneath the player at Overworld spawn. Falls back to minecraft:bedrock if the configured block/mod isn't present. |
voidNether |
true |
Voids Nether terrain entirely. |
voidEnd |
true |
Voids End terrain while preserving the fountain, obsidian spikes, and dragon fight. |
Structure generation is always disabled in every void dimension — this is no longer a configurable option.
Void One Block is designed to work great on its own, but it shines alongside Random Item Generator Resurrected — your starting block becomes a mystery item source, turning the classic "one block" survival challenge into a proper progression loop.
(Random Item Generator Resurrected is an optional dependency — Void One Block works fine without it.)
