-The materials are specially made for each render engine and not converted

-This stool can be used indoors and outdoors

-For Corona Render: it is recommended to install a version not lower than 1.5, since the glossiness of the materials is configured with PBR in mind.

-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
