issues with face over lapping and generator ranges

[_Aka_]

you are the best.

Thank you

One last question, is there a way to iterate on the extruded mesh vertices on road edge so I can get their position, then i can use the position to generate my own custom mesh.

The extruded mesh is made of successive shapes linked between them. All the shapes have the same number of vertices. So if your shape is rasterized into 10 vertices, then iterate on yourMesh.vertices by jumping 10 vertices at each iteration to get the same vertex on each shape
