Who works in a V-Ray version lower than 3.1 be careful, in the materials in the BRDF section there is a Microfaset GTR (GGX), 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. You also need to add the VRayDisplacementMod modifier to the chair itself (a screenshot of the settings is in the archive).

For Corona render, it is recommended to install a version at least 1.5, since the glossiness of the materials is configured with PBR in mind.
