About this project
What does Technical Engineering 4 add?

Welcome to Technical Engineering!
Introduction
Technical Engineering 4 (TEN4) is the official fourth-generation sequel to the Technical Engineering mod series. Built around the concept of "General Autonoma," it provides a highly modular and configurable automation framework. TEN4's tech tree spans the complete industrialization process from basic FE-powered machinery to quantum computation. New content accepts both vanilla and newly added resources as inputs and interfaces with vanilla mechanics, allowing players to build complex control systems without learning a new logic language.
Features
Automation. TEN4 provides a complete automation toolchain, simultaneously supporting energy, item, and fluid transport, with conditional routing and programmable logistics capabilities. Devices offer powerful control features—each type of input and output can be individually configured, and comparator output is supported for advanced redstone integration.
Configurability. From individual machine processing speed and energy capacity to the overall balance curve, the vast majority of parameters are exposed through configuration files, tag systems, and other means. Modpack authors and advanced players can adjust mod behavior to suit their preferences without resorting to code-level modifications.
Flexibility. Every device serves multiple legitimate functions. This design reduces the need for excessive single-purpose machines.
