Masterful Machinery Upgraded

[1.21.1-0.12.0] - 2026-10-12

Added

• Fluid volumes show a port's fluid inside the machine, filling up as the port fills. Add a visuals list to a structure with { "type": "fluid_volume", "from": [x, y, z], "to": [x, y, z] }, or "area": "K" to fill every spot of layout key K. "port": "K" picks which fluid port it shows; without it, any fluid port in the machine. From KubeJS, .fluidVolume(from, to, port) and .fluidArea(key, port).
• PneumaticCraft air ports show their pressure on the controller screen.

Fixed

• /reload now updates placed controllers. New or changed processes used to stay unused until the controller was broken and placed again.
• The debug tool no longer fails in singleplayer with duplicate entry.
