Create Nuclear Ore Gen Tweaks
A small NeoForge addon for Create Nuclear that makes uranium, lead, and striated ore-deposit generation configurable.
It does not add new ores and does not replace Create Nuclear's configured features. Instead, it overrides the corresponding placed features and reads placement settings from a NeoForge common config when new chunks are generated.
Features
- Configure uranium ore placement attempts per chunk.
- Configure lead ore placement attempts per chunk.
- Configure how rare Create Nuclear's large striated deposits are.
- Configure minimum and maximum generation height for each deposit type.
- Choose one of four vertical distributions:
uniformtrapezoidbiased_to_bottomvery_biased_to_bottom
- Built-in config screen through the NeoForge Mods menu.
- Keeps Create Nuclear/Create's own
config_filter, so their ore-generation toggle still applies.
Requirements
- Minecraft
1.21.1 - NeoForge
21.1.93or newer for Minecraft 1.21.1 - Create
- Create Nuclear
Tested with Create Nuclear 1.3.2-beta.3.
Install the mod on both the server and clients in multiplayer.
Configuration
Open:
Mods → Create Nuclear Ore Gen Tweaks → Config
Or edit:
config/cnoregen-common.toml
Restart the game or server after editing the file directly. Changes affect only chunks generated after the new settings are loaded. Existing chunks are not regenerated.
Default values
| Deposit | Frequency | Height | Distribution |
|---|---|---|---|
| Uranium ore | 4 attempts per chunk | Y -128 to 0 | biased_to_bottom |
| Lead ore | 8 attempts per chunk | Y -128 to -64 | uniform |
| Striated deposit | 1 attempt per 18 chunks | Y -128 to 0 | biased_to_bottom |
count controls placement attempts, not the number of ore blocks inside a vein. Vein shape and size remain controlled by Create Nuclear's configured features.
For striated deposits, rarity = 18 means one placement attempt for approximately every 18 chunks. Larger values make them rarer.
How it works
The addon replaces these Create Nuclear placed-feature data files:
createnuclear:uranium_ore
createnuclear:lead_ore
createnuclear:striated_ores_overworld
The replacement data uses three lightweight placement modifiers registered by this addon:
cnoregen:config_count— reads the configured attempts per chunk.cnoregen:config_rarity— reads the configured one-in-N chance.cnoregen:config_height— reads the configured height range and distribution.
The original configured features, ore blocks, vein definitions, and Create config filter are left intact.
