Topology of geometry:

- forms and proportions of The 3D model most similar to the real object
- detailed enough for close-up renders
- the geometry of the model was created very neatly
- almost no many-sided polygons
- the model is ready and does not needed smoothing modifiers

Materials and Textures:

- Blender files included Standart materials and Shaders
- large size textures included

Organization of scene:

- to all objects and materials names in scene are appropriated
- real world size (system units - mm)
- coordinates of location of the model in space (x0, y0, z0)
- does not contain extraneous or hidden objects (lights, cameras, shapes etc.)
