Lucid Blocks World Generation Guide

Directories

Terrain, weather, vertical layers, spawn tables, building blocks, and soundtrack.

Dungeons, towns, temples, pyramids, and other large constructions placed inside biomes.

Trees, rocks, pillars, mushrooms, houses, and other small objects scattered across the world.

Vertical cycle

The overworld loops vertically. 30 biome layers stack on top of each other, each 256 blocks tall. Climb or dig past 7,680 blocks and you come back to the same sequence.

Your layer is decided by Y. Terrain noise can shift the border up or down by about 32 blocks, so layer edges ripple. Within a layer, your X and Z pick one of the biomes assigned to that layer; each biome in the list has its own frequency weight.

The overworld references 122 biomes. Most sit in the two layers around spawn: 59 in Eden Surface and 16 in Underground Eden.

Core numbers

Constants used by the overworld generator.

Field	Value	Meaning
Biome width (X, Z)	32	How wide a single biome pick is.
Layers per cycle	30	Stacked vertical layers before the loop repeats.
Layer height	256	Blocks of Y per layer.
Cycle height	7,680	30 layers × 256. Travel this far on Y and you loop back.
Boundary jitter	±32	Terrain noise shifts layer borders by up to this much.
Spawn layer	6	Y = 0 lands in Eden Surface. New worlds spawn at roughly Y = 54.
Default seed	3	The Generator resource's internal default, overwritten at runtime by the per-world (hashed) seed.

How biomes get picked

Biomes do not blend. Every point in the world falls into one 32 × 32 cell, each cell carries one biome pick, and edges get a second pass that cleans up slivers.

Field	Value
Grid	A 32 × 30 × 32 grid of biome picks wraps around the world. Same cell on a different seed still holds the same biome. Y changes the pick because Y shifts which row of the grid you read.
Edge cleanup	Before a cell confirms its biome, the game checks a small ring of nearby cells (five across X, five across Z, three stacked on Y). If any of those disagree with the center, the cell blanks out. Slivers and thin biome patches never reach the world.
Minimum footprint	The cleanup pass is why biomes have clean straight edges and a visible minimum size. A biome will not appear as a one-block sliver next to a larger neighbor.

Layer map

Open biome directory

The 30-layer cycle from top Void down through Naraka. Y ranges are for flat ground; terrain noise shifts the borders by up to 32 blocks either way.

Dimensions

Eight separate worldspaces. Only Naraka uses the full layered cycle. The other seven run single-biome worlds — most with fixed native terrain, Alma with a generated dungeon maze.

Naraka

131 biomes

The ordinary qualia. Full 30-layer vertical cycle with 122 biomes, structures, decorations, and day/night spawns. All normal gameplay happens here.

How you get there	Default starting dimension. Portal blocks return here from other dimensions.

Pocket

1 biome

Single pocket biome. No mob spawns. A personal building space separate from the main world.

Field	Value
Generator	pocket_generator
Biomes	1
Spawn	Y 17
Kill plane	—
Resets	No

Music	Abandoned World
How you get there	Svargaqualia block (portal). Requires Divine world flag.

Firmament

1 biome

Dimension of a grass grid with some plants, grass, and a unique sky effect. Spawns Ofanim and Principality. Places the Janqualia Block as the return portal. Leaving the bounds (Y below −64 or above 512) drains health. When leaving you will be returned to where the Dominion touched you.

Field	Value
Generator	firmament_generator
Biomes	1
Spawn	Y 1
Kill plane	Y < −64 or Y > 512
Resets	Yes
Weather	snow
Music	Silence
How you get there	A Dominion touching the player teleports them in. There is no entrance portal block.

Challenge

1 biome

Challenge arena. No biome-level spawns — the challenge spawns its own vermin. Leaving the arena bounds (Y below −64 or above 512) drains health. After 2 retries, a third death ends the challenge and returns to Naraka.

Field	Value
Generator	challenge_generator
Biomes	1
Spawn	Y 0
Kill plane	Y < −64 or Y > 512
Resets	Yes
Weather	—
Music	Dream Fight / Mindful Killing / Salad Slaughter / Factory Invasion (random)
How you get there	Challenge cutscene from a Cutscene Block.

YHVH

1 biome

YHVH boss arena. No biome-level spawns — the boss encounter is scripted. Death returns you to Naraka without clearing beads.

Field	Value
Generator	yhvh_generator
Biomes	1
Spawn	Y 1
Kill plane	—
Resets	Yes

Alma

1 biome

A single dungeon biome: a maze of plaster-block walls with the occasional white lamp and sometimes (very rare) a Janqualia. It lists Agate as its spawn, but natural spawning only runs in Naraka and the Firmament, so the corridors stay empty. The walls are flat plaster blocks with no texture variety.

Debug biome with white sky. Used for development testing. Not accessible in normal gameplay.

Field	Value
Generator	debug_generator
Biomes	1
Spawn	~ground (raycast down from Y 100)
Kill plane	—
Resets	No
Weather	—
Music	—
How you get there	Debug portal block. Only available when debug mode is enabled.

What a biome carries

Each biome brings its own block list, its own vermin pools, and its own weather. Every chunk is filled from these fields.

Field	Value
Building blocks	The solid-ground block list. Some biomes use one block; others mix dirt, grass, and foliage.
Random decorations	Trees, rocks, pillars, mushrooms, houses. Each biome sets its own spawn frequency.
Water decorations	A separate pool for water surfaces.
Structures	Towns, temples, dungeons, pyramids. Each biome carries its own weight for each structure.
Day and night vermin	Two independent spawn pools. Spawn rates sit between 0.0 and 6.0.
Rare chunk chance	How often a chunk in this biome triggers rare placement rules.
Weather	Rain in 6 overworld biomes, snow in 13, nothing in the other 103.

Fixed terrain dimensions

Five dimensions and the Gallery biome do not use the normal block list. Their terrain is set by the game itself, so the biome data page shows no building blocks.

Dimension / Biome	Terrain blocks
Firmament	Grass, grass foliage, plants, and the janqualia block. The janqualia block doubles as the return portal.
YHVH	Holy ground.
Challenge	Arena shape comes from the active challenge, not the biome.
Pocket	A single Osmium pillar that pokes out of an infinite ocean.
Creative	Flat plane of Essence Block.
Eden — Gallery	A random draw from the full block registry. Foliage, internal, respawn, and heaven blocks are skipped. Layer 6 gallery also places essence block.

World limits

Hard edges, kill planes, and retry rules per dimension.

Field	Value
Horizontal reach	No border. Terrain streams in around you out to 48, 64, 80, or 96 blocks depending on your render distance.
Vertical cycle	Infinite loop. 30 biome layers × 256 blocks = 7,680 blocks per full pass.
Kill plane — Naraka	None. Falling forever is survivable.
Kill plane — Challenge	Leaving Y −64 … 512 drains health.
Kill plane — Firmament	Leaving Y −64 … 512 drains health.
Challenge retries	2 extra attempts per session, added in 2.9.3. A third death ends the challenge.
Side-dimension resets	Challenge, Firmament, and YHVH forget all world data every visit. Naraka, Pocket, Alma, Creative, and Debug persist.
