This little program lets you draw spline roads onto grayscale height maps that then can be used in iClone (5 or 6).
It has a lot of controls for how the road the road follows the terrain. Width, cut, etc. are all there.
Fairly easy to figure out as well.

This is amazing! I'm definitely planning to use this for something...
