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
