The model uses materials that may not be displayed correctly in very old versions of the engine.
Quincey carpet from Eco Kilim in two sizes:
1700*1200 mm
2900*2000 mm
The carpet is made by geometry
The pile material is made using Displacement in the material settings
(for more general angles, I recommend using lower Displacement values - 1 mm, for close angles - 3 mm or more)

The object is a single one, textures and materials have logical names
Texturing Unwrap UVW
For Corona render, it is recommended to install a version not lower than 1.5, since the glossiness of materials is configured with PBR in mind
Who works in a V-Ray version lower than 3.1 be careful, there is a Microfaset GTR ( GGX) in the materials in the BRDF section, if your version is older than 3.1, then the BRDF field will be empty. Choose Blinn, Phong or Ward – which is preferable for you
