Force Unity Terrain to be flat-shaded?

Is it possible to force a Unity Terrain to look flat-shaded? I am making a game with a kind of old-school, flat-shaded polygon look (think Virtua Racing kind of thing), but I’d like to retain the editing convenience of Unity Terrain.

Is it possible to foce the terrain to use a very simple shading model that doesn’t apply smoothing, etc.?

I don’t think so. From what I remember you use textures not materials to paint on the terrain…

I am actually wrong!!! There are terrain shaders now!
