Buildcraft-Legacy
by Thepigcat76
Buildcraft-Legacy ports the Buildcraft pipe, machine and engine set to NeoForge, giving 1.21.1 players pipes, tanks and oil processing with newer textures.
What it does
The port brings back Buildcraft's transport network for NeoForge: item pipes, fluid pipes, crates and tanks move and hold materials between machines. Engines that run on redstone, Stirling power, combustion or creative current supply the machines, and advanced filters control what each pipe accepts. Oil processing is part of the included machine set.
The author describes the project as a port of the original Buildcraft, with new textures and features aimed at players who remember the older mod. It is in early stages and is prone to bugs, and the author notes that adding features and maintaining the many mods they work on means the timing may vary strongly. Porting Dead Libs is required, and the mod is released for NeoForge 1.21.1 only. Servers that run it need every player to install it too. The code is under the Mozilla Public License 2.0, so Buildcraft-Legacy is open source, with public links to the source and the issue tracker.
Key features
Item and fluid pipes

Power engines
Engines run on redstone, Stirling, combustion or creative current, and supply power to the machines they connect to.
Advanced filters

Tanks, crates and oil
Tanks store fluids and crates store items, and oil can be processed as part of the included machines.

Use cases
Rebuilding a Buildcraft setup
Players who used the original Buildcraft can rebuild a similar pipe and engine setup on NeoForge 1.21.1.
Who it’s for: The mod suits players who want the older Buildcraft pipe and engine layout on a NeoForge 1.21.1 world. Because the project is in early stages, players who want a fully stable base may prefer to wait for later releases.
