What it does

Research progress on a chosen item type opens infinite replication of that type in the engine. The engine analyzes an item's structure, including its NBT data, and completely consumes the input when the consumeItems option is set to true, which is the default. Resources are placed in the engine's extraction slot, and the author describes the design as a next-generation Equivalent Exchange system.

The server and every player need the mod installed. Forge is the only loader listed, and the latest file is 2.1.2 for 1.12.2, dated 2026-06-02. The first release came out on 2026-05-09. The source code and issue tracker are public, but the mod is not open source, and it is released under All rights reserved.

Key features

Automatic research consumption
An optional setting consumes research items on its own, which removes repeated clicking through the research screen.
Hand-drawn interface
The GUI uses hand-drawn 2D pixel art, with progress bars that shift color and animate as work advances.
Adjustable GUI layout
X and Y offsets for the GUI buttons can be set in the config file, so they do not overlap the inventory.
Compatibility with other mods
The author states compatibility with HBM's Nuclear Tech and Techguns, which track deep NBT energy and damage data.
