Feature generation/1.18.1-0.3

This page covers Voluminous Energy's feature generation for 1.18.1 (0.3) (0.3 Beta 1 to Beta 2). All values are the defaults of the common config file (voluminousenergy-common.toml) and can be changed there.

Technical background

Features are still added in code through Forge's BiomeLoadingEvent, now using Minecraft 1.18's placement modifiers (HeightRangePlacement, InSquarePlacement, CountPlacement, RarityFilter). This is the first version with:

• deepslate ore variants and Red Saltpeter Ore,
• an "Exposed Discard Chance" per ore (the chance that a blob touching air is not placed),
• ore deposits,
• height anchors updated for the deeper 1.18 world (Galena, Rutile and Eighzo moved down, Cinnabar and Saltpeter up to 320).

The config still calls the per-chunk count "Weight". It was renamed "Count" in 1.18.2.

Ore blob features

Ore blob placement (all use uniform height placement)

Ore	Biomes	Count per chunk	Bottom anchor	Top anchor	Size	Exposed discard chance
Saltpeter	DESERT or MESA category	4	55	320	33	0
Bauxite	Neither NETHER nor THEEND	16	10	60	8	0
Cinnabar		9	1	320	6	0
Galena		3	-48	12	6	0
Rutile		3	-64	-32	4	0.75
Eighzo	THEEND	1	1	36	4	1

What each ore replaces

Ore	Replaces → places
Saltpeter	forge:ore_bearing_ground/colorless_sand → Saltpeter Ore forge:ore_bearing_ground/red_sand → Red Saltpeter Ore
Bauxite, Cinnabar, Galena, Rutile	minecraft:stone_ore_replaceables → regular ore minecraft:deepslate_ore_replaceables → deepslate ore
Eighzo	forge:ore_bearing_ground/end_stone → Eighzo Ore

With an exposed discard chance of 1, any Eighzo blob that touches air is discarded completely. Since much of the End is exposed to the void and to surface air, Eighzo is noticeably rarer in this version than in 1.18.2-0.3.1.2 and later, where the chance was lowered to 0.5.

Ore deposit features

Ore deposits are added to every biome except the Nether and the End, at the "Underground Ores" step. Each one is placed on average once every chance chunks. "Disallow surface ore deposits" (default false) stops deposits from generating where they can see the sky.

Ore deposit placement

Deposit	Height placement	Bottom anchor	Top anchor	Chance (1 in N chunks)	Enabled by default
Copper	Triangular	-16	320 (see note)	26	Yes
Iron	Triangular	-64	74	56	Yes
Gold	Triangular	-64	-48	112	Yes
Bauxite	Uniform	10	60	64	Yes
Cinnabar	Uniform	-64	320	56	Yes
Galena	Uniform	-48	12	78	Yes
Rutile	Uniform	-64	-48	128	Yes
Eighzo	Uniform	1	36	192	No

Copper deposit top anchor bug: in 1.18.1 the copper deposit reads the Cinnabar deposit's top anchor (320) instead of its own "Copper Ore Deposit Top Anchor" (112), so copper deposits can generate up to Y 320 and changing the copper setting has no effect. This was fixed in 1.18.2.

Crude Oil features

Oil features are added to every biome except the Nether and the End, at the "Lakes" step, between the bottom and top of the world.

Feature	Chance (1 in N chunks)
Surface Crude Oil lake	144
Underground Crude Oil lake	16
Crude Oil geyser	208

Rice

Rice is placed once every 32 chunks on average, in every biome except the Nether, the End and oceans (oceans can be enabled with "Generate Rice in Oceans"). A rice plant is only placed where the chosen block is empty and has water directly below it.

Rice height bug: the intended range is Y 48 to 320, but in 1.18.1 the top anchor setting was registered under the same config name as the bottom anchor ("Rice Bottom Anchor"). Both therefore read the same value, which defaults to 320, so every attempt is made at Y 320, where there is never water below. As a result, rice should almost never generate naturally in 1.18.1 with default settings. Changing "Rice Bottom Anchor" moves both ends of the range together, so rice can only ever be attempted at that single height (for example 63, the block above sea-level water). This was fixed in 1.18.2, which has separate "Rice Bottom Anchor" and "Rice Top Anchor" settings.
