Smoothing roads on terrains is a pain when map making, especially on sloped roads. The smooth tool is only really good for flat surfaces, and the smooth slope tool just makes my roads even bumpier. The world editor could really use an improved smooth tool where it makes smoothing roads much easier. Right now, in order to get smooth roads, I have to export the heightmap to another application (Blender) and use the sculpting tools to smooth it out and then import it back in as a new terrain. This process is too tedious and any roads and scenery I placed will have to be redone. Also, I think it would be useful to be able to select a decal road and click a button to automatically level and smooth them.
I hope a new smooth tool will come in the future! Can't wait! Driving on the roads in my map is like trying to drive on rocks at high speed!
