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

Renders for the preview were made in Corona Render 9. On the Corona Legacy Mtl model. Corona Render version 1.5 or higher is required. Materials were converted to V-Ray using V-Ray scene converter.

Some objects have a Turbosmooth modifier applied to them during rendering (geometry for smoothing). Adjust the smoothing level as needed.

Poly: 50 152
Verts: 52,264

In the model:
Choreographic/ballet barre in three variations
Composition of mirrors with illumination
Set of a mat, a fitness band, a strap, a roller for MFR, balls for self-massage and a thermos / water bottle

All my models are optimized, made for anti-aliasing (where it is needed). They do not have unnecessary geometry and unjustifiably heavy maps. All archives are as light as possible without losing quality. All objects and materials are logically named.

"For Corona Render: it is recommended to install version not 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. Choose Blinn, Phong or Ward - what is preferable for you."
