When I get to the end of a cliff with my build and place a foundation that overhangs the edge even a small bit, I have to build a tower of foundations to the next elevation to support the one foundation I want that is only 5% overhanging the cliff.
I would foundations to get support just from touching the ground mesh, regardless of having some overhang.
I like this.
I'd also love to have pillars behave like foundations since that would make cliffside builds look so much better than just stacks upon stacks of foundations.
