According to the API listed on the roblox developer site, the Terrain object only has methods that allow you to clear all terrain, add terrain or edit the properties of terrain. Is there any way to clear selected areas of terrain dynamically in-game without clearing all of it and pasting what you want to keep?
function ClearTerrain(Cframe,Size) workspace.Terrain:FillRegion( Cframe, Size, Enum.Material.Air) end ClearTerrain(CFrame.new(0,0,0),Vector3.new(100,100,100))
It's simple, but next time at least do some research. I shouldn't have to search up "How to clear a specific region of terrain", and find out that its the first result. Cmon.
