There is 1 copy of the model saved in the scene, and the customized material is assigned to the model. There are 6 spheres next to the model, each with its own material applied to it.

All the objects have normal names.
All materials have convenient names.
All textures have a unique name.

The Turbosmooth modifier is assigned to the model in the scene in Render Iterations=2 mode, which is applied only during rendering.
The obj file contains a model without using Turbosmooth.

The Pivot Point is aligned to the center of the model.

Those who work in V-Ray versions lower than 3.1 be careful, the materials in the BRDF section contain Microfaset GTR (GGX), if your version is older than 3.1, then the BRDF field will be empty. Choose Blinn, Phong or Ward, whichever is preferable for you.

For Corona render, it is recommended to install a version not lower than 1.5, since the glossiness of the materials is configured with PBR in mind.
