Re-posting "I'm the only one who can't figure this out" multiple times isn't going to help you, tell us what you're getting wrong
for one how to I make the roof inside the house flat, because the bottom of the top/bottom brick is textureless
plus how do I make it so that I don't need flat bricks to fill in the gaps left by roofs
I also want to know how to make a semi ramped/flat roof
