Block Veins
Block Veins adds naturally generated ore veins of resource blocks to the Overworld, placed in caves.
What it does
Block Veins adds veins of resource blocks such as diamond, gold, emerald, iron and lapis blocks to the Overworld terrain, where they generate naturally. Veins are placed in caves and only form where a single block is exposed to air, so they show up while exploring rather than at random underground.
The mod is server-side only, so players join a server running it without installing anything. It is published for Forge and NeoForge, with files for 1.20.1, 1.21.10 and 1.21.11, and it is released under the MIT License but is not open source.
Key features
Resource block veins
Veins of diamond, gold, emerald, iron and lapis blocks generate naturally in the Overworld.
Cave placement
Veins spawn inside caves, so they are found while exploring underground passages.
Exposed-face rule
A vein only generates where exactly one of its blocks is exposed to air, which keeps the placement readable.
