A tool that turns a hand-drawn spline into ready-to-use two-way traffic splines for the Farming Simulator 25 traffic system.
Select the spline you drew along the middle of the road and apply: the script automatically generates a forward spline and a reverse spline (...Reverse), parallel to each other, aligned to the ground, and placed inside the map's splines > trafficSplines structure — creating the groups itself if they don't exist yet.
Key features:
- Configurable lane offset distance (with a suggested minimum safe value)
- Maximum distance between points, to control how detailed the generated spline is
- Align to terrain or to objects (asphalt, bridges), never placing the spline below ground
- Option to generate AI splines instead of traffic splines
- Automatic crossroad grouping
- Automatic end-connection between segments drawn separately
- Point snapping and a safety-distance circle while editing
- Left-hand traffic option, for maps where traffic drives on the left
- Settings window with collapsible groups, plus in-editor documentation and changelog
- UI translated into 12 languages
Works equally well on maps with just a handful of traffic splines or hundreds of them.
