Use Generic Presets in V-Ray for SketchUp to apply predefined settings to a Generic material.
Overview
Generic Presets apply predefined material or environmental settings to an asset. Applying a preset completely replaces the asset's current configuration. Every parameter value changes to the value in the selected preset. Child assets, such as linked textures, are disconnected or deleted depending on their hierarchy level.
