Custom Virtual Vein
by Non_coffee
Custom Virtual Vein lets server owners define connected virtual ore veins of varying sizes across world chunks, configured through files and extracted with Multiblocked2 custom machinery.
What it does
Virtual veins are placed in the world as data rather than as blocks. The vein size, the chunks they occupy and the conditions under which they yield output are all set in configuration files. A machine built with Multiblocked2 reads the configured vein and produces output from it, so the mod connects vein generation to crafting-style machinery.
Each vein condition can be written inside a recipe condition. A recipe input that is arbitrary cannot set a vein, but a recipe output must set one. After the settings are saved, the primary, intermediate and advanced vein detectors show a vein's location and power, and a vein view displays the veins that exist in the loaded world. Placing a configured machine over a chunk then extracts the vein that corresponds to it, at the power the chunk holds.
Custom Virtual Vein requires Multiblocked2, which must be installed next to it. The mod runs on Forge and is published for 1.20.1 only, with the latest file 1.0.3 for 1.20.1, released on 2026-05-24. Because it is a client and server mod, the server and every player need it. The code is all rights reserved and is not open source.
Key features
Configurable vein sizes
Virtual veins can be set to different sizes and placed across world chunks through configuration files.
Recipe-driven vein conditions
Vein conditions are written inside recipe conditions, so a recipe output can require a vein and an input cannot.
Vein detectors
Primary, intermediate and advanced detectors locate veins, and a view shows the veins present in the world.
Multiblocked2 machinery
Configured machines extract the vein of the chunk they are placed over, at that vein's power.

How it compares
Block Veins is server-side only and uses the MIT License, with files for 1.20.1 – 1.21.11, so players need nothing installed. Multiblocked2 is client and server and open source under the GNU Lesser General Public License v3.0 only, and it is the machinery base this mod depends on rather than a direct replacement.
