To be fair I doubt something like this is possible, and if it is I assume it’d be incredibly difficult.
An in-game editor similar to a game engine map editor that allows a player to build up (or build down) surface areas on maps such as smooth dirt.
Basically the ability to create things such as hills or holes within your condo (Specifically Smooth Dirt).
To be honest I’m not sure how such a feature would or could work. In fact it may just break the purpose of smooth dirt being… well… smooth.
This all probably sounds incredibly stupid, in which I apologies for. Please give some feedback on this.
