Corona version 9
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
