Ok, so build the road in another 3d modeling program, import a terrain into that program, use a drape function like cloth to lay the road on the terrain, then export the road into vue and paint the eco system around the road?
That is something I can do in 3dmax. I just need to make sure the road is thick enough to protude through the terrain when back in vue and the cloth material in 3dmax is thick enough not to pick up the minor bumps in the terrain.

Thats the biggest problem. When you make a terrain the average person would build a road that hugs the ground, up and down mountains and so fourth. In vue even using the python script  for roads, it simply rasies the terrain to a specified height, so it you want a road that wraps around a mountain from bottom to tip it cant be done.

I hope someone fixes this, because as a film maker I was looking to VUE to do a shot that would cost $40k if done in real life. All the things Vue can do and something as simple as a road is almost impossible.

Thats interesting. Have you seen any that show asphalt roads?
