With EasyRoads it is faster and convenient the terrain alignment. Also when need to edit the road network, for example, moving an intersection all connected roads adjust.
After reading your posts I decided to have a go at making my own roads in my 3D modelling software (I'm using Softimage XSI which is sadly now defunct

), and I'm quite pleased with the results so far but I forsee a few issues further down the line so I'm just wondering how you went about constructing your roads.
Did you create your road network as a single mesh ?
I made my roads as a set of tiles - one tile for a straight section, one for a curve and another for a junction etc.and then put them together in the editor, but I can see how this might be a problem later on if and when I start to vary the terrain height. So I was wondering how you went about making your roads as they look so nice.
