- To display the relief of the rope fibers, you need to enable Displacement in the render settings
- Who works in a 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 - which is preferable for you.
For Corona render it is recommended to use version 1.5 or higher.
