Version Corona 9
Materials CoronaLegacyMtl
In versions CoronaRender 6 and lower, CoronaLegacyMtl=CoronaMtl
For Corona render, it is recommended to use a version no lower than 1.5, as the glossiness of materials is set with PBR in mind.

Version Vray 5
Materials VRayMtl
Those working in V-Ray versions lower than 3.1 should be careful, as the materials in the BRDF section use Microfacet GTR (GGX); if your version is older than 3.1, the BRDF field will be empty. Choose Blinn, Phong, or Ward – whichever is preferable for you.
