if necessary and taking into account the use in close foreshortenings

if necessary, you can disconnect all elements from the object with one click:
1- Translate an Editable Mesh Object
2- assign explode (it is slightly lower) with a value of 100, confirm
3 - optionally back to Editable Poly

========================================
Who works in the 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 install a version of at least 1.5, since the glossiness of materials is adjusted for PBR

Enjoy your use and beautiful renderings!
