Well traditionally for my models all objects have correct names in English there are materials and multi-materials which are also renamed textures are also renamed. All the textures painted by myself.

[!] IMPORTANT. Materials for rendering V-Ray if the automatic conversion of materials for Corona Render passes with problems your scene hangs or is destroyed I cannot bear responsibility for this. Open and convert the model in a separate scene.

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.
