Tengo el V-Ray Objects, pero no está activado el FUR

En la Barra de Herramientas tengo el V-Ray Objects, pero no tengo activado el Fur, alguien me puede ayudar con este problema. Muchas gracias.

What version of V-ray are you using? Are you really using SketchUp 5 as you put in your profile?

Make sure that you have a group selected first…then Fur icon will activate’

Here it is greyed out since the geometry is not grouped:

Here it is grouped and now Fur can be used:
