Seamless textures are used. For best results on large visible areas I advise you to use a UVW randomizer for a diffuse texture (CoronaUvwRandomizer VrayUVWRandomizer).

It is recommended to install the version of Corona at least 1.5 since the glossiness of materials is configured with PBR in mind.

Those who work in V-Ray versions lower than 3.1 be careful in the materials in the BRDF section there is Microfacet GTR ( GGX ) if your version is older than 3.1 then the BRDF field will be empty. Choose Blinn Phong or Ward – whichever suits you best
