Hi. For all fans of "Dirt Rally" helps to search "modders" of tracks of Dirt Rally, you can open the path of the tracks with "3dsimed" I have no knowledge to edit beyond the textures, I think that based on the tracks by default you can change the route, I even think new tracks. Seek help modders who want to add or modify their own tracks, if they know any help communicate this. Below I leave the link as the tracks are the 3dsimed, thinking it may be possible with the BTB editor, hopefully we not find people to join.
