Corona 11 version
Materials CoronaLegacyMtl + Vray
In versions of CoronaRender 6 and below CoronaLegacyMtl=CoronaMtl
CoronaLegacyMtl requires a version of Corona Renderer at least 1.5, since the cards are designed to use PBR (roughness-metallic)

Version Vray 6
Vray materials obtained using Vray-converter
Those who work 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 - whichever is preferable for you.
All cards are designed for the PBR roughness-metallic workspace.
