Marking Fluid

Marking Fluid is a color-coding tool that prevents Copper Transport Pipes from connecting to each other. Use it to segment networks and run multiple independent pipe systems side-by-side.

Usage

Right-click Copper Transport Pipes with marking fluid to color-code them:

  1. Craft marking fluid with desired dye color
  2. Right-click copper pipe with marking fluid
  3. Pipe takes on the dye color
  4. Pipes will only connect to other pipes of the same color
  5. Different colored pipes will not connect to each other
  6. Unmarked pipes connect to all colors

Removing Marking

To clear a pipe's color marking: - Sneak + right-click with empty hand - Pipe returns to unmarked state - Can now connect to any pipe

Connection Rules

Same color pipes: - Connect to each other - Form isolated networks by color

Different color pipes: - Do not connect to each other - Keeps colored networks separate

Unmarked pipes: - Connect to all pipes regardless of color - Can bridge between different colored networks

Use Cases

Run parallel networks: 

[Red pipes] ═══ [Red network A] (red only connects to red)
[Blue pipes] ══ [Blue network B] (blue only connects to blue)
    (Red and blue networks remain separate)

Isolate same-colored networks: 

[Green network A] → [Green pipes only]

[Green network B] → [Green pipes only]
    (Two separate green networks won't merge)

Organize complex builds: 

Different colored pipes for different purposes:
- Red = ore processing
- Blue = item sorting
- Green = overflow management

Tips

  • Only works on Copper Transport Pipes
  • Each dye creates a different color
  • Sneak + empty hand to remove marking
  • Visual indicator shows pipe color
  • Alternative to physical separation
  • Cleaner than using blocks to separate networks
  • Different from filters - this prevents physical connections
