3ds max 2016 for Corona (CoronaLegacyMtl) and V-Ray + obj. Preview rendered in Corona 11.

The model is made for anti-aliasing. Turbosmooth with 1 iteration is used in the scene.

Important! The Weighted Normals modifier was used on the model. If you need to make adjustments to the models geometry, use the Edit Normals modifier, select all normals and Reset them, then collapse the stack.

For Corona Renderer: it is recommended to install version not lower than 1.5, since the glossiness of materials is configured taking into account PBR.

For V-Ray versions lower than 3.1: in the materials in the BRDF section there is Microfaset GTR(GGX), if your version is older than 3.1, the BRDF field will be empty. Select Blinn, Phong or Ward - what is preferable for you.
