A road and lot editing tool that lets creators lay out nodes and segments, then generates road surfaces, borders, bridges, junctions, markings, props and parking lots as chunked meshes. It stores a graph of nodes and Bezier segments, builds arc-length tables and cross-sections, and runs a rebuild pipeline that produces PolygonMesh geometry and prefab placements. Profiles and styles are GameResources that define materials and parameters, and the code has debug helpers and stable hashing for change detection.
An editor plugin that lets creators draw and edit road networks, lanes, and parking lots, and conform terrain to the roads. It has scene tools for selection, drawing, lane editing, lot placement, and terrain shaping, with gizmo previews and sidebar UIs. Picking helpers, gizmo renderers, and undo-wrapped edits tie it together, and a debug dump writes border data for inspection.
