V-Ray for Rhino whare are the buttons ?

Hi I installed V-Ray for Rhino, in command it says: Loading V-Ray for Rhino, version Dec 19 2008 13:30:00

but where are the buttons ?

Hi
You have to make V-Ray your current rendering engine. Click on the “Render” menu on the main Menu and then click on “Current Render” then select V-Ray as your current render.
