Feature generation/1.17.1-0.2
This page covers Voluminous Energy's feature generation for 1.17.1 (0.2) and 1.18 (0.2). All values are the defaults of the common config file (voluminousenergy-common.toml) and can be changed there. Where 1.18-0.2 differs from 1.17.1-0.2, both values are given.
Technical background
Features are added in code through Forge's BiomeLoadingEvent. Unlike 1.16.5 and earlier, the config now uses absolute anchors: an ore picks a height uniformly between its bottom anchor and top anchor. Nothing is added to Nether biomes, and only Eighzo is added to End biomes.
These versions have no deepslate ore variants, no Red Saltpeter Ore, and no ore deposits. All of those were added in 1.18.1-0.3.
Ore blob features
| Ore | Biomes | Replaces | Count per chunk ("Weight") | Bottom anchor | Top anchor | Size |
|---|---|---|---|---|---|---|
| Saltpeter | Desert category, Badlands, Eroded Badlands | Sand, Red Sand | 4 | 55 | 256 | 33 |
| Bauxite | Any biome that is not Nether or End | minecraft:base_stone_overworld | 16 | 10 | 60 | 8 |
| Cinnabar | 9 | 1 | 256 | 6 | ||
| Galena | 3 | 12 | 32 | 6 | ||
| Rutile | 3 | 1 | 16 | 4 | ||
| Eighzo | End biomes | End Stone | 1 | 1 | 36 | 4 |
In 1.18-0.2 the anchors were not changed for Minecraft 1.18's deeper world, so no ore generates below Y 1. The minecraft:base_stone_overworld tag includes deepslate, so ore blobs that reach deepslate replace it, but they place the regular (stone-textured) ore block, because deepslate variants don't exist yet.
Crude Oil features
Oil features are added to every biome except the Nether and the End. The number is the average number of chunks per feature: a lower number means more features.
| Feature | Height range | 1.17.1-0.2 chance | 1.18-0.2 chance | Generation step |
|---|---|---|---|---|
| Surface Crude Oil lake | 1.17.1: 5 above the bottom of the world to the top 1.18: bottom to top | 1 in 65 chunks | 1 in 144 chunks | Lakes |
| Underground Crude Oil lake | 1.17.1: 5 above the bottom of the world to the top 1.18: bottom to top | 1 in 15 chunks | 1 in 16 chunks | Lakes |
| Crude Oil geyser | Bottom to top of the world | 1 in 100 chunks | 1 in 208 chunks | Lakes |
Rice
Rice generates in every biome except the Nether, the End and oceans (oceans can be enabled with "Generate Rice in Oceans").
- 1.17.1-0.2: 32 placement attempts in every chunk, between Y 55 and the top of the world.
- 1.18-0.2: once every 32 chunks on average, between Y 48 and 384.
