Textures were rendered in good quality
The structure of the material allows you to change the size of the pile (through tiling), if you need to change the size of the carpet.

The object is single, textures and material have logical names

For Corona render, it is recommended to install a version of at least 1.5, since the glossiness of materials is configured taking into account PBR

Those who work in V-Ray versions lower than 3.1, be careful, in the materials in the BRDF section there is Microfaset 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
