Rhino materials can be converted to V-Ray ones by changing their Type or using the vrayMtlFromRhino command. This action is reversible and is available for all Rhino material types, including PBR materials imported from Substance files (.sbsar).
The benefit of converting a Rhino material's type to V-Ray is to make it available for editing in the Asset Editor, where additional parameters and functionalities help it achieve photorealistic appearance.
From the context menu, you can reset the material parameters to their default values using the Reset to Defaults option.
