My goal is to create fully customizable, lane-level roads for engineering previews, with applications in driving and racing games, municipal transportation design, architectural visualization, and more. With minor modifications, you can make your own assets compatible with my add-on and expand your asset library independently, rather than being limited to what I provide.

To improve the interaction and performance of road editing, I modified Blender’s source code and introduced new nodes through AI-assisted development. These include Point Gizmo for generating handles, Attribute Output for persistently storing handle data, and Curve Intersections for handling intersections between curves.

These nodes form part of the road editing workflow. The accompanying custom Blender build provides the full node interaction experience, and I plan to add more nodes as practical production needs arise.
