Smallerveins
Small mod that caps the Ore vein size to a set amount and allows to reduce spawn rate overall
About this Mod
SmallerVeins
A simple Minecraft mod that gives you more control over ore vein generation.
This project was made to give players an actual incentive to make farms/factories, not intended to be played on its own (you could definitely do that as well if you want to)
Features
- Limit vein size – Cap the maximum size of all ore veins.
From personal experience, Sizes smaller than 4 result in almost no ore veins at all, especially in caves, since most attempts there fail anyway - Reduce spawn chance – Make ore veins generate less frequently
Configuration
| Option | Default | Range | Description |
|---|---|---|---|
maxVeinSize |
4 | 1–64 | Maximum size of any ore vein |
genChance |
100 | 0–100 | Chance (%) that a vein generates at all |
