The archive contains FBX OBJ MAX files for Corona 1.7 (PRB) and VRAY 3.6 (Microfacet GTR / GGX) renders.
Render is made in Corona render. Who works in the V-Ray version is 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 the BRDF field will be empty. Choose Blinn Phong or Ward – which is preferable to you. For Corona render it is recommended to put a version not lower than 1.5 since the glossiness of materials is adjusted to fit PBR. After import apply anti-aliasing.
