CoronaLegacy Mtl + Vray Materials

The TurboSmooth modifier is applied to the model during rendering

Polys:716 Verts:742 (without TurboSmooth)

For Corona render, it is recommended to install version no lower than 1.5, since the glossiness of materials is configured taking into account PBR.

If you're using a V-Ray version earlier than 3.1, please note that the BRDF section in your materials will show Microfaset GTR (GGX). If your version is older than 3.1, the BRDF field will be empty. Select Blinn, Phong, or Ward—whichever is more preferable for you.
