Armchair: Laskasas MIUZZA Chair Dimensions: 1500x900x770mm Style: Modern Units: Millimeters Render: Vray, Corona Formats: 3Ds Max 2012, OBJ When using a model in obj format, add a turbosmooth modifier. When using a model in max format, enable the turbosmooth modifier. ======================================== For those who work in a VRay version 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 - which is preferable for you. ======================================== For Corona render, it is recommended to install a version of at least 1.5, since the glossiness of materials is configured with PBR in mind.
