again it turned out exactly as planned, so i guess we did figure out how this works.
here's our material list:
BOARDS
35 plum
25 cypress
BLOCKS
100 cypress
STONE
151 feldspar
99 cinnabar
so, again, according to jorb's guide, the 1st and 2nd wood are defined by the BLOCKS you put, not the boards.
the 3rd and 4th wood are defined by the BOARDS and not the blocks.
so if you want a house with the 1st wood like cypress and the 2nd wood spruce, you'll want to have about 55 of cypress and 35 of spruce.
and the same goes for boards, you have to have at least half as much as the 1st wood for the second.
not sure if i'm making myself clear, but anyways, that's how it works for the stone mansion at least. we tested twice and it worked perfectly.
