Gregnautics

Gregnautics is a hard tech-survival modpack built around TerraFirmaCraft, Create, GTCEu and Create: Aeronautics

Gregnautics combines TerraFirmaCraft survival with GregTech-style industrial progression and Create-based mechanical automation. Early progression is grounded in TFC: geology, metalworking, food, climate, charcoal, bloomery processing, and hand-forged tools matter before machines take over.

As the pack opens up, Create and its addons become the bridge between manual survival and industrial production. Mechanical processing, lathes, saws, mixers, compacting, thermal recipes, rubber production, wiremaking, gears, springs, rods, plates, and other components are reworked to fit TFC and GTCEu instead of existing as disconnected duplicate systems.

GTCEu provides the main long-term technology backbone: material tiers, electricity, chemistry, advanced alloys, machines, and high-end automation. Duplicate metals, fluids, plates, sheets, wires, gears, rubber, coke products, and other overlapping items are gradually unified so recipes use one coherent material progression.

Create: Aeronautics is integrated as a later-game engineering goal rather than a separate sandbox. Flight and advanced mechanical systems are intended to sit on top of the same metallurgy, rubber, electronics, and machine chains used elsewhere in the pack.

Main features:

  • TerraFirmaCraft-based survival and metallurgy
  • GTCEu 8 tech progression
  • Create automation adapted to TFC materials
  • Reworked recipes for metals, rubber, electronics, gears, springs, wires, rods, plates, and tools
  • Deduplicated materials across TFC, GTCEu, Create addons, and other mods
  • More realistic alloying, forging, casting, heating, and machine-processing chains
  • Create: Aeronautics progression integrated into the pack economy
  • Custom KubeJS compatibility and balancing scripts

Note: this pack currently depends on a SNAPSHOT build of GTCEu 8.
