-V-Ray render
-Corona render (CoronaPhysical materials, therefore in Corona 6 and below the materials will not be read)

- Turbosmooth modifier applied to models (display in viewport - 0 iterations, 2 iterations on render)
Those who work in V-Ray 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 - what is preferable for you
