Number of Meshes/Materials/Textures/Blueprints:49/39/35/3

Extra Assets Provided: a number of basic low poly meshes of roads, intersections and props, with multiple UVs for texturing, AO and lightmapping, along with textures(road texture is 1024x1024px) and materials, suitable for mobile or VR purposes.

Size: about 106 MB.

Additional Notes:

  • only one low poly vehicle mesh is included, vehicles do not detect collisions for now, a path must consist of unidirectional road splines
