Create: Pipes'n physics
by StaticFX
Create: Pipes'n physics replaces the pipe and pump behavior of Create with a physics-based fluid engine for NeoForge 1.21.1.
What it does
Fluid flow in its pipe networks is calculated from the structure of each network. Fluid tanks generate pressure in connected pipes, so two connected pipes level out their fluid and move it downhill without any pump. Pumps act as boosters that lift fluid a set number of blocks, and the lift no longer depends on a fixed range: a pump supplies head to the whole network.
Viscosity and density set how fast a fluid flows and how hard a pump has to work to lift it. Siphon effects emerge from the same rules, and an open-ended pipe on a titled tank loses fluid. A tank's weight changes with its contents, density affects that as well, and a vessel's angle or center of gravity shifts how fluid moves through it. The mod also adds cross-level piping and a custom renderer that keeps fluid drawn parallel to its flow.
Create: Pipes'n physics is open source under the MIT License. It requires Create, and the optional Sable dependency is supported. A server running it needs every connecting player to have it too. Files are published for NeoForge 1.21.1 only, with 3.2.1 as the latest build from 2026-09-10.
Key features
Physics-based fluid engine
Flow in each pipe network is computed from the network's structure instead of fixed pump ranges.
Pressure from tanks
Fluid tanks create pressure in connected pipes, so fluid levels out and moves downhill on its own.
Pumps as boosters
Pumps add lift of a set number of blocks and supply head to the whole network, with no range limit.
Viscosity and density
Each fluid's viscosity and density determine how fast it flows and how much lift it needs, and siphons form from these rules.
Dynamic tank weight
Tank weight changes with the fluid inside, and a vessel's angle and center of gravity shift how fluid moves.

What the author says
Pipes'n Physics overhauls Create's pipe and pump system with a new physics based engine. Flow is calculated based on the pipe networks structure. Pumps dont have ranges anymore, but supply head to your network and can lift fluid blocks.
