Corona version 9
Materials CoronaLegacyMtl + Vray

CoronaLegacyMtl requires a version of Corona Renderer at least 1.5 since the cards are designed to use PBR (roughness-metallic)

Vray materials are obtained using Vray-converter
Who works in a V-Ray version lower than 3.1 be careful there is a Microfaset GTR ( GGX) in the materials in the BRDF section 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.
All cards are designed for the PBR roughness-metallic workspace.
