This article helps you find why V-Ray for SketchUp buttons Add Fur, Convert to Clipper and Mesh Light can be grayed out.
Overview
Sometimes the buttons for Mesh Light, Fur and Clipper are grayed out. At first glance, this might cause some confusion as to whether or not the tools are actually working/usable.
For more information on how to use the tools described below, visit the Geometry page.
Cause and Solution
This is a standard and expected behavior linked to the way SketchUp functions and more specifically, to how it handles geometry. In short, geometry, which is not Grouped (Make Group) or made into a Component (Make Component) lacks certain functionalities. To put geometry into Group or Component:
