The archive contains the 3ds max 2015 scene for Corona and V-Ray + fbx files.

The renderers for the preview are made in Corona Render 9. On the Corona Legacy Mtl model. A version of Corona Render at least 1.5 is required. The conversion of materials to V-Ray is performed using V-Ray scene converter.

The Turbosmooth modifier is applied to the bag during rendering (geometry for smoothing). Adjust the degree of smoothing as you need.

Poly: 15 859
Verts: 16 773

All my models are optimized, made for smoothing (where it is needed). They do not have unnecessary geometry and unnecessarily heavy maps. All archives are as light as possible without loss of quality. All objects and materials are logically named.

"For Corona Render: it is recommended to install a version not lower than 1.5, since the glossiness of the materials is configured with PBR in mind.

Who works in a V-Ray version 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, then the BRDF field will be empty. Choose Blinn, Phong or Ward – which is preferable for you."
