Start with nothing, build everything.
Large total conversion mods.
Map generation and terrain modification.
using gear girl and !skins makes it so you cannot hand craft void buildings besides the sheds https://i.imgur.com/Pp4R9aw.png i dunno if this is an issue with !skins or with this mod.
The tooltip still says the engineer can craft it, so hand crafting should work. If it doesn't, it would seem to be a problem with the other mod.
I gave this some more thought and I think I figured out a solution. Voidcraft 1.4.5 should resolve this issue.
