Stack + Deform mesh along a path

For my current project i need stack + deform a mesh along a path.

I found a video where is shown what i need.
Thats the video: Unity Blog
The problem is where to get this?

It looks like that project is going to bi published in the EasyRoads3D packet for 49$.
The problem is that the EasyRoads3D need a Terrain to work.
The project is designed for the Ipad2 and terrains + Mobile = does not work.

Has anyone a idea where to find something like in this video or got a idea how to build it for at my own?

Hi Malzbier,

Only just saw your post. What you see in the video can be done with EasyRoads3D. The roads tool by itself works with the terrain object. The procedural objects tool can be used without the terrain object. You can easily use that to create roads.

Or why not use the roads tool on a low resolution terrain object and export the terrain to .obj afterwards? Many people do that for mobile / iOS development…
