Shape Carpet Collection by Benuta
Carpet textures were rendered in good quality
The carpet material has a complex structure, where you can separately change the scale of the pile if necessary.

Objects are uniform, textures and material have logical names
For close angles, I recommend adding TurboSmooth

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
