Create Nuclear Ore Gen Tweaks
by Vasys
Create Nuclear Ore Gen Tweaks lets server owners configure how uranium and lead striated ore deposits are placed in newly generated chunks, and it requires Create Nuclear.
What it does
The addon makes the placement of uranium and lead ore in Create Nuclear adjustable. Its NeoForge common config sets how many placement attempts per chunk are made for uranium and for lead, how rare the large striated deposits are, and the bounds of generation height for each deposit type. Four vertical distributions are available, including one biased toward the bottom of the world.
The addon replaces the placed-feature data files of Create Nuclear with three lightweight placement modifiers, while the original configured features stay intact, so vein shape, size and the ore blocks themselves remain under Create Nuclear's control. Create Nuclear is required as a dependency. The mod runs on client and server, so both the server and every player need it, and it is released under the MIT License as open source for 1.21.1 only, with NeoForge as its only loader.
Key features
Per-chunk placement attempts
Uranium and lead ore each get their own placement attempt count per chunk, set in the config file.
Striated deposit rarity
A rarity value sets how often large striated deposits appear, where 18 means roughly one attempt per 18 chunks and larger values are rarer.
Height and distribution control
Minimum and maximum generation height can be set per deposit type, with four vertical distributions to choose from.
Applies to new chunks only
Changes affect only chunks generated after the settings load, and existing chunks are not regenerated. The game or server must be restarted after editing the file directly.

Use cases
Who it’s for: Server owners running Create Nuclear who want to change how uranium and lead deposits are spread across new terrain. Players who keep the default placement can leave the addon out, since it only changes generation parameters.

What the author says
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…
