Autonomous mid-size city bus concept.

Geometry:

• No isolated vertices
• No coincident vertices
• No coincident/coplanar faces
• Correct face normals
• No empty objects

Topology:

• Quads and Triangles only
• Model can be cleanly subdividable

Other:

• lighting and cameras are not included in the product (Model file includes only the 3D model)
• Model Scale: real-world scale
• Model centered at origin (0,0,0)
• all objects are named and logically grouped
