Masterful Machinery Upgraded

[1.21.1-0.7.0] - 2026-09-12

Added

• Nuclear Radiation port. With Nuclear Radiation installed, mm:nuclear_radiation/radiation ports store radioactive isotopes, measured in Bq.
  • Put radioactive items in an input port and it absorbs their radiation.
  • Recipes can use a specific isotope ("isotope": "nr:u_235") or any radiation, and can make radiation as an output.
  • Output ports load radiation onto items, so it can travel from one machine to the next.
  • Stored radiation decays at its real half-life unless "decay": false.
  • Ports are sealed by default; "shielded": false makes a port irradiate the area around it.
  • isotopes, carriers and loadPerItem limit what a port accepts and loads.
  • See docs/radiation.md.
• Energy past 2.1 billion FE. Energy port capacity, maxReceive and maxExtract, and energy amounts in recipes, can now go above 2,147,483,647 FE. Other mods still move at most that much per transfer.
• anyOf structure key. One spot can accept any of several keys, each with its own settings: { "anyOf": [ { "portType": "mm:item", "maxTier": 8 }, { "block": "minecraft:iron_block" } ] }. Works the same from KubeJS.

Fixed

• Free matter tanks now fill. Matter input ports set up with tanks and no matter never took anything from the network. Each free tank now pulls one of the matter types the machine's recipes use.
• The docs said a per_tick energy amount is taken every tick. It is the total for the whole recipe, spread across it. The docs and examples now say so.
