Hey Devs. Here is a suggestion/request. Please add roof valleys to the menu. Make them if you have to There are hips, but no valleys that i can find, and this doesn't allow for nice roof systems. Fortunately with the green house, glass roof pieces i was able to take the hip piece, use setangle x 180 to flip it upside down and it works well enough for a valley, as you can see in this screenshot. But, i can't do that with solid pieces, because the top and bottom are not the same. This is something that should have been added to FO4 from the beginning.
