Who works in Vray -in Paradise version lower than 3.1 be careful, in the materials in the BRDF section there is a Microfacet GTR (leaning), if your version is older than 3.1 , then the BRDF field will be empty. Choose a Pancake, Fong 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 the materials is configured with PBR in mind.
