Traffic Spline Builder for Giants Editor

A handy tool for Giants Editor that converts hand-drawn splines into ready-to-use two-way traffic splines for the traffic system. Simply select the spline you drew down the middle of the road and apply the script: it automatically generates a forward spline and a reverse spline (...Reverse), aligned parallel to each other and to the terrain, and places them inside the map's splines > trafficSplines structure – creating the groups itself if they don't already exist. Key features:

• Configurable lane offset distance (with a suggested minimum safe value)
• Maximum distance between points to control spline detail
• Align to terrain or to objects (asphalt, bridges) – splines are never placed below ground
• Option to generate AI splines instead of traffic splines
• Automatic crossroad grouping
• Automatic end-connection between separately drawn segments
• 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 or hundreds of traffic splines.
