Hello, I'm not sure if this is currently possibly due to the way its currently implemented but would it be possible to change the Y axis starting point for raise ground? My idea is to place a buildable floor and start the raise ground only above said floor. This would allow you to create a tunnel effect by excavating a mountainside > building your tunnel with floors as the roof > raising the ground from the placed floor upwards and leaving a hollow section underneath. This would emulate the tunnel/underground base in anything other than a generated boulder. It doesn't have to be the floor just an example. Is it possible for something like this? Cheers RangeCreed
