Create: Pipes n Physics 3.0.0

For Create 6.0.10 on NeoForge 1.21.1. Existing worlds load fine, but pipe networks behave differently.

Features

Fluid lives inside the pipes

• Pipes are no longer instant wires: every pipe block holds real fluid (250 mB by default). Sources drain as the front advances, sinks fill when the column arrives, and nothing is duplicated or lost. Breaking a pipe spills its contents.

• Rendering shows the actual pipe contents: trickles run shallow, pressurized lines pack full, idle runs settle to the tank's waterline. Works on dedicated servers.

• Siphons must be primed once and then keep their prime. Pumps no longer self-prime a dry suction line (enablePumpSelfPriming restores it).

• Two fluids forced together break the pipe, with Create's reaction (water + lava → cobblestone).

• pipeVolumePerCell = 0 restores legacy instant transfers.

Centrifuge (requires Sable)

• Spinning contraptions fling fluid outward through the plumbing.
• New centrifuge recipes: a fast-spinning tank separates a mixed fluid, products route to radial taps by density.
• Public API

Gases

• Lighter-than-air fluids flow up through pipes, pool in the highest tank, and equalize correctly between tanks.
• A tank of gas provides lift on a Sable contraption (enableGasBuoyancy).
• Molten fluids flow 3× faster in ultrawarm dimensions (nether for example).

Valves

• One-way mode: a direction dial turns any fluid valve into a check valve, with in-world direction arrows for goggle/wrench holders.
• The throttle is now cranked by shaft rotation or a Valve Handle; the scroll box is replaced by the direction dial.

Displays, Ponder, readouts

• Display link sources for pipe flow, pump output, and tank contents.
• Ponder scenes for pump, pipes, valves, and the physics, running the live engine.
• Pour particles at open mouths and into tanks.
• /pipegraph: live overlay, per-pipe flow history, and an engine report for any machine block.

Bug Fixes

• TFMG: coke ovens serve a different fluid per face; blast stoves no longer crash the server and connect through their real ports.
• Create Propulsion: chained burners fill as one network; a tank stacked on a burner no longer drains into it (thanks @SpyC0der77).
• Create Diesel Generators: distillation tower inputs stay fillable.
• CROWNS: fixed parallel pump transport that silently vanished fluid.
• Broken fluid capabilities from other mods no longer crash the server.
• Pipe and tank waterlines match on screen; gravity drains stop exactly at the pipe opening.
• Basins drain from any level and separate multi-fluid contents completely.
• Fixed oscillations: pipe↔tank ping-pong, gas churn between tanks, horizontal mouths drinking their own spill.
• New pumpDrainAnyLevel option to ignore the connection height when pumping from tanks.

Performance

• Network layouts are cached between ticks instead of re-scanned every solve (enableNetworkCache).
• Contraption pipe scans on Sable sub-levels are cached, cutting idle tick cost with ships present.
