Hi! I have a question about how traffic splines work in MapToPlay.
When I generated the map for the first time, the tool correctly identified the roads. I applied the buffer, refined the edges to make them smoother, and used roadbed to level the terrain. Then I used the road constructor, and everything worked perfectly.

When I entered the game, one of the road splines was working fine.
Later, I went back to the editor, made some adjustments, and for some reason, my splines were no longer generated on the map.

I reimported everything again, but that didn’t solve the issue.

Since you’re the creator, could you explain how splines are generated or what I should do to make them appear again?

Suggestion:
It would be great to have a tool that generates only the splines for future use in Giants Editor. For example, when creating a road, each segment could generate a spline—even if not used for traffic—so it could later be adapted in Giants Editor. In my case, I don’t use traffic in my maps; I only use splines as a base for AutoDrive.

@XLFarmsProjects Traffic splines are generated during export from the lanes configured in Road Constructor. If the road geometry or lane connections change, the export may skip those splines. For vector edits, use Select to click a feature and move, insert, or delete its vertices. Use Draw for new points, lines, or polygons, then wait for the edit to save before exporting again.

A spline-only export for AutoDrive would be a useful feature request.

Cheers!

It could be something like a line companion tool, but designed to generate a spline.
