TFC-MI Compat is a small NeoForge compatibility module for Minecraft 1.21.1. It does not add new blocks, items, or world generation. Instead, it changes how TerraFirmaCraft and Modern Industrialization interact, so a single world can move from hand-made stone tools to a powered factory without either mod having to be played in isolation.
Why this exists The two mods were built independently. TerraFirmaCraft expects fuel, manual handling and slowly accumulated metal; Modern Industrialization expects tagged machine parts, power grids and energy capabilities. On their own, several of their systems do not recognise each other. This module bridges those points where configuration files and KubeJS scripts cannot, using a small set of mixins and commands.
Features and what they change for the player
- Fire bricks in MI multiblocks. Modern Industrialization's structure checks accept any block carrying the #c:fire_bricks tag. A player who has already fired TFC fire bricks for a kiln or a bloomery can use those same bricks to build MI machines, instead of producing a second unrelated brick type just to satisfy a structure check. Early pottery and brickwork therefore stay useful well into the industrial stage.
- Electrically heated crucibles. TerraFirmaCraft crucibles can draw electric power. Instead of standing next to a crucible and feeding it fuel by hand for every batch, a player can wire it into the same grid that runs the factory and keep metal casting going while doing other work.
- Capability bridge. Standard NeoForge capabilities are translated between the two mods. Energy and fluids produced on one side can be consumed on the other, so a TFC-side device and an MI machine can form one continuous production line rather than two separate loops with manual transport in between.
- Chunk-based quarry veins. Quarry output follows the ore veins actually present in the chunk. Prospecting and choosing where to place a quarry remain meaningful decisions in the late game, instead of the quarry yielding an identical fixed list of resources everywhere.
What a playthrough looks like A player starts by knapping stone, firing clay and forging the first tools. Later, the same bricks they learned to make are accepted by industrial multiblocks; the crucible they once heated by hand can be powered from a generator; and prospecting results still decide what the quarry yields. The early work is not discarded when the machines arrive - it becomes the input to them. That continuity is the reason to use this module: it lets one world carry both halves of a long tech progression.
Requirements and scope Requires TerraFirmaCraft 4.x, Modern Industrialization 2.x, and NeoForge on Minecraft 1.21.1. All four behaviours above are adjustable in config/tfcmi_compat-common.toml. No new blocks or items are registered, so adding or removing this module does not change the item registry of an existing world. This is an early release developed alongside a modpack; values and behaviour may change as either mod updates.
