DynamiDucts

A Minecraft NeoForge mod for 1.21.1 that brings back the Thermal Dynamics legacy duct system. Build pipe networks to transport items, fluids, energy, and even players.

Features

Ducts

• Energy Ducts (Fluxducts) transfer RF/FE between machines. 6 tiers from Leadstone to Cryo-Stabilized.
• Fluid Ducts (Fluiducts) transfer fluids between tanks. Hardened variants handle extreme temperatures. Super Laminar variant has unlimited throughput.
• Item Ducts (Itemducts) move items with configurable routing. Impulse variant for faster travel. Flux-plated variants also carry energy.
• Transport Ducts (Viaducts) send players between endpoints. Wrench a face to create an endpoint, right-click to pick a destination.
• Structural Ducts provide non-transferring structure for relay networks and covers.
• Lux Ducts emit light when powered by redstone.

Attachments

• Servos extract items/fluids from adjacent inventories into the network. 5 tiers with increasing speed, stack size, and multi-slot extraction.
• Retrievers pull items/fluids from remote inventories back to the retriever's location.
• Filters control what passes through duct-to-duct connections. Supports whitelist/blacklist, mod sorting, and component matching.
• Relays transmit redstone signals through structural duct networks using 16 color channels.
• Covers disguise ducts as any block. Craft a cover item with any solid block in a crafting grid.

Network Features

• Items visually travel through transparent ducts and bounce back when destinations are full.
• Fluids are shared across the entire network as a single tank.
• Redstone control on all servos, retrievers, and filters (Disabled / Low / High).
• Route types: Nearest-First, Furthest-First, Random, Round Robin.
• Dense and Vacuum item ducts for path weight control.
• Long Range Viaducts for double-speed player transport. Linking Viaducts connect separate networks.

Materials

The mod adds its own ingots and nuggets for metals used in recipes: Lead, Tin, Silver, Invar, Electrum, Bronze, Signalum, Enderium, and Lumium. All metals are tagged with the c:ingots/<metal> and c:nuggets/<metal> conventions, so any mod providing the same metals (Mekanism, Thermal Series, etc.) will work interchangeably.

Simple alloy recipes are included so the mod is fully playable standalone without other tech mods.
