Forge Multiblocks in 1.7.2 are not supported by buildcraft 6.16 with builder.
Later on I will try it with 6.17 and 1.7.10 - but i still fightingl with updating my server :-)

I plan on making a mod that makes bc pipes and other mod's cables/pipes microblocks compatible, that is with Forge Multipart, when I have finished my wardrobe mod and jaffacake mod, if no one has done it yet.

@Dijkstra1 - @amadornes has already been working on that and I have made massive improvements to the API to make this possible in the future; perhaps you two could collaborate?

@Chicken-Bones oops, i saw it like microblocks :D

Argh, I'm confused with naming convention in this thread. There means Forge Multipart or Immibis's Microblocks? Anyway Buildcraft provide schematic support only for itself and vanilla, nothing other.

It's modders (in this case Immibis's) work to provide support for schematics.

Hahah, immibis. It's up to either buildcraft or a plugin mod to add support for this.

Needless to say, we're very happy to provide support for people implementing schematics! Closing this issue.

You have to ask another modder with enough time and motivation to make a compatibility module.

this means, BC don´t want to support Forge Multipart with builder or the problem is schematic format don´t support it? So, who I have to ask, because I think I am not the only one, who like to see nice BC-builders placing Forge Multipart blocks?
