Hello! BuildCraft 6.3.2 is out, and with it – a few minor additions and a lot of highly important bugfixes, as is the norm for tiny point releases. Grab it here.

EDIT: And also, BuildCraft 6.3.3 is out, fixing a few miscodings and leftover debug code.


  • [#2381] Individual robot blacklist (asie)
  • [#2377] Make swimming in oil a lot harder (Vexatos)
  • [#2376] Make oil behave like lava? (asie)
  • Add block description support to facades (asie)
  • Add fluid/power number hiding support (immibis/asie)
  • Add support for connected textures using getIcon() in facades (asie)
  • Make facade lookups much less strict (asie)


  • Performance optimization for auto workbenches (immibis)
  • Performance optimization for block breaking robots (hea3ven)


  • [#2404] Bug in energy consumption routine (asie)
  • [#2397] Inventory not updating properly when removing pluggables (asie)
  • [#2389] Facades added through IMC only allow crafting of metadata 0 in multiplayer (asie)
  • [#2388] add-facade IMC checks block.getRenderType() on server (asie)
  • [#2386] Vanilla logs not facadeable (asie)

  • Check if another mod added fluids before us (asie)
  • Fix docking stations staying linked when changing a robot’s main link (hea3ven)

After a short beta run, I am mostly confident that we can have a stable release of BuildCraft 6.3. As always – some other mods might crash with it while they update their APIs.

Get them at the usual download page.


BuildCraft 6.3.1


  • Pluggables, when removed, go directly into your inventory


  • [#2368] Cannot place torches on facades (asie)
  • [#2366] Startup crash in Blueprint Library (asie)
  • [#2362] No construction marker recipe (asie)
  • Pluggables can be removed more freely again (asie)


  • Updates to German, French, Hungarian, Japanese, Russian, Slovak and Chinese (various authors)

BuildCraftCompat 6.3.1


  • Compatibility with Iron Chests for builder schematics
  • Partial compatibility (~50% of blocks) with Carpenter’s Blocks (block, stairs, slope, daylight sensor, pressure plate, gate, safe, ladder) for builder schematics

EDIT: BuildCraftCompat is now out, fixing a crash bug with FMP!

Double release today! After almost a month of wait, I am proud to announce the release of two new betas!

First off is BuildCraft 6.3.0, with a lot of new features, which I’m sure many of you BuildCraft fans will enjoy. They range from new features (lenses, filters), improvements (GUI scrolling, Quartz Gates) to bugfixes (NPEs, quarry fixes).

Second, however, is a new mod. We call it “BuildCraftCompat”. It adds compatibility code to BuildCraft for support of external mod APIs. Currently, we support:

  • CoFH inventory APIs (for inventory connection and item pipes – yes, tesseracts now work!),
  • MineTweaker recipe APIs (the syntax is very similar to the BC 6.0 syntax MT had),
  • NEI integration (NEI Integration recipes + ledger overlay support),
  • FMP integration (for the Builder – thanks ChickenBones!),
  • RedLogic integration – freestanding bundled cables now connect to pipes and can be controlled with gates (currently off by default, as it’s experimental).

More support is planned soon! This is the first release and I’m very excited about what you do with the new features in BC and BCC 6.3.

BuildCraft 6.3.0 changelog follows.


  • 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:

  • Massive rendering improvements (especially in terms of shading) (ganymedes01)
  • Reduced pipe item network packet size (asie)
  • Optimized TileEntity lookups (asie – with thanks to skyboy)

  • [#2353] Liquid dupe bug with BlockTank (asie – with help from mezz)
  • [#2348] NPE when removing a docking station of an unloaded robot (hea3ven)

  • NPE in ResourceId (asie)
  • Rare NPE in Assembly Tables (asie)
  • 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 – SHOULD be mostly backwards-compatible
  • Unused functions removed from buildcraft.api.core.
  • PipePluggable API refined enough to let people define custom PipePluggables.

EDIT: Released BuildCraft 6.2.6, which does an urgent update to the RF API (fixes newest CoFH mods, Ender IO?) and fixes a crash bug with fluids. Sorry!

BuildCraft 6.2.5 is out today, and with it come many small improvements and tweaks – just like you have come to expect from us! Download it from the usual download page.

PS. By the way, if you have been experiencing Filler/Zone Planner/Builder lag with WAILA – an update from ProfMobius is coming very, very soon to fix that…
