Terrain from freeform curves
The "Create Terrain" component does not really care what kind of curves it gets. It does not have to be flat curves or uniform curves or conform to any other restrictions.
As such you can create terrains from quite freeform curves. You can draw you terrain around a house and vary the height of the curve as much as you like.
Or you can draw any kind of shapes that tilt and toss and the component will create a terrain that matches the curves as you like.
Only restriction to note is that the curves cannot cross each other. Or rather they can and the components wont even complaint about it but if the point where the curves cross each other is not at the same height the tools will have a tough time figuring out you one curve height is more important than another and it will create a messed up terrain mesh. When chaining "Edit Terrain" components curves from one component can overlap curves from others though as the last curve will allways take precedence.
Thats it. Go make some freeform terrains!
