Set of book stands, book holders, book racks.

All my models are optimized, made for smoothing (where necessary), it is possible to regulate the number of iterations. Similar objects are multiplied via Instance, there is no unnecessary geometry and unjustifiably heavy maps. Archives are as light as possible without losing quality, objects and materials are logically named.

The archive contains a 3ds max 2021 scene for Corona and V-Ray + fbx and obj files.
Materials for Vray are created using Vray Converter.

Renders for the preview were made in Corona Render 10. On the Corona Legacy Mtl.
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

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. Select Blinn, Phong or Ward - what is preferable for you.
