Changelog for BuildCraft 6.3.0


  • Lenses! Crafted from an iron ingot, a dye and a piece of glass in an Assembly Table, they are used to color items passing through them on pipes. (asie)
  • Yes, you can stick them on the sides of pipes. Fancy!
  • Filters! Replace an iron ingot with a bar in the lens recipe to filter items passing through by color.
  • Facade rework: hollow facades are now explicit, separate items, craftable in the Assembly Table. (You can also turn existing regular facades to hollow facades and back.) (asie)
  • More machines can now be controlled with gate actions (asie)
  • Lapis and Daizuli pipes can have their colour set with a dye (asie)
  • Multiple pulses with Autarchic Pulsars are now back (asie)
  • Quartz Gates! Inbetween Iron and Emerald gates, they contain 2 trigger/action sets with 1 parameter for each! (asie)
  • Fuel energy production rate config option (marcin212)
  • Gate and chipset recipe cost multiplier options for modpack developers (asie)
  • Gates and wires now glow in the dark when active (ganymedes01)
  • Pipe wires have a slightly improved texture (CyanideX)
  • GUI improvements:
  • You can now use the scrollwheel in Gates (to scroll through triggers and actions) and Zone Planners (to zoom in and out) (asie)
  • F5 now refreshes the zone planner map (asie)
  • Chutes can now be powered with Engines, much like wooden pipes, to extract items; however, they have a 10 RF/t cap (asie)


  • Adjusted quarry speed to return pre-RF speeds (asie)
  • Massive rendering improvements (especially in terms of shading) (ganymedes01)
  • Reduced pipe item network packet size (asie)
  • Optimized TileEntity lookups (asie - with thanks to skyboy)

  • Wooden pipes used 10 RF too many in rare edge cases (asie)
  • Wooden power pipes could not have gates for checking energy in nearby machines (asie)

For modders:

  • New API: IRedstoneEngineReceiver - does what the name says it does.
  • Massive buildcraft.api.transport/buildcraft.api.pipes rework.
  • Unused functions removed from buildcraft.api.core.
  • PipePluggable API refined enough to let people define custom PipePluggables.
