When I playtest the game and begin to build on the ground it’s frustrating because it starts to build beneath the ground and would be pretty annoying for players to put up with that… I don’t now what could be causing the problem. I have been removing the floor and adding a whole new ground like 6 times already but no matter what I can still build beneath the floor, and if I put the ground higher when I build a wall when playtesting half of the wall is clipped through the ground, so I aligned it as best as I could so it does not do that but regardless it will still let me build beneath the ground.
As you can see I can build under the ground.
Another screenshot under the ground to show how it looks like. Can anyone please help? been stuck on this for awhile.
