I’m trying to follow along and thought it was easy enough while creating the basic assets, but then I discovered they’re not truly following the grid lines when I thought they were so I’m going to have to go back and fix them so they stick to a standard proportion.
Looking at it more closely now, I realize the problem lies in creating the walls like the door and window are off scale. Going back and using the square as a reference for size should fix it. I’ll update with my findings.
