Technical Engineering 4
by Licphel
Technical Engineering 4 is the fourth-generation sequel in the Technical Engineering series, a NeoForge tech mod for 1.21.1 that adds logistics devices and a modular automation framework.
What it does
The mod is built around General Autonoma, a configurable automation framework. Its tech tree covers the whole industrial path, from basic machinery powered by FE energy to quantum computation. Newly added resources and machines accept both vanilla and mod inputs, and they interface with vanilla blocks.
Machines can be tuned through configuration files, tags and other means. Processing speed, energy capacity and most other parameters can be adjusted for each machine, which lets modpack authors and advanced players shape the mod without editing code. Players can also wire up control systems through the mod's mechanics without learning a new logic language. Because a single device often serves several functions, the design needs fewer single-purpose machines.
The mod is published for NeoForge only, with files for 1.21.1. Every player and the server need a copy of the mod. It is released under the MIT License, and the source code and issue tracker are public.
Key features
Modular automation framework
General Autonoma gives machines a shared structure that can be combined into larger automated production lines.
Industrial tech tree
Progression runs from FE-powered machinery through to quantum computation, covering the full industrialization process.
Vanilla compatibility
New resources, inputs and interfaces connect with vanilla blocks and items, so existing worlds can be extended instead of replaced.
Configurable machine parameters
Processing speed, energy capacity and most balance values can be changed through configuration files and tags.
Logic-free control systems
Control systems are assembled from in-game mechanics, so players can automate without a separate programming language.

How it compares
Grid and FE is a NeoForge mod for 1.21.1, also released under the MIT License and open source, with a similar client and server environment. Grid Engineering is another NeoForge mod for 1.21.1, open source under the MIT License and used on both client and server. Technical Engineering 4 is a fourth-generation sequel with its own tech tree, whereas those two focus on their own grid and engineering systems.
