Hello,

I am building an urban scene involving roads and streets on which vehicles will travel. Unlike many of the pre-made urban scenes, my scene has changes in elevation throughout the town.  Does anyone have experience or suggestions on how to get roads to conform to hilly terrain?

Thanks,

Nathan

you have a few choices -

1 - easiest -  just paint it on,  and use bump maps to add any extra detail.   ( which you can do with sculptris or blender - both of which are free,  but take a moment to learn ...sculptris being the easier of the 2 )
2 - intermediate -  there's a software on steam called - Race Track Builder -  where you make a terrain and conform tracks and roads to it.-  you create the whole terrain with track in that software then may have to export that direct x file to blender to convert to obj.
3 - intermediate / advanced -  rigging a track -  adding bones to a road / track model then shaping it in scene to your terrain. - ironically enough probably the ugliest of these 3 choices because the bones will bend the tracks with slight corners so any curves won't be smooth / round.

Greetings, Direx

Unity has multiple assets that let you paint roads onto terrain. I assume it would allow you to export the objects as well.

Thanks to everyone for your advice.
