Hallway 3d model
If you work in V-Ray version lower than 3.1 be careful, the materials section in the BRDF is Microfaset GTR ( GGX ), your version is older than 3.1 , then the BRDF field will be empty. Choose Blinn, Phong or Ward, whichever is more preferable for Corona render, it is recommended to use version 1.5 or higher, since the glossiness of materials is adjusted for PBR.
Enjoy using it and have a good projects =)
