heyas; i did a quickie short bit of road on my latest pic. it was on top of a plateu, so it wasn't too difficult. doing a windy road over hills and mountains mighte be tougher. i duplicated the terrain and gave the second one the road (actually cobblestones) texture, then shrank it down on the z (vertical) axis. then i went into the terrain editor with the original terrain (with grass material) and set a shallow 'dig' along where i wanted the road to be. keep in mind that it is hard to see where what is on the terrain preview, so it might be a good idea to try to paint it in the 2d app, like bop suggests.
