Rendering interior with Vray

Hi, I am trying to render an interior using Vray, however it just keeps coming out black!! Even though i have added lights etc. Please Help!

Hi Meghewitt,

the problem you describe could have multiple reasons so to get a better answer its better to upload a file.
until then try the following: open a new rhino instance, copy all your content to to the new file and assign grey material to all objects inside vray. start an interactive rendering. If the rendering is still black there is most likely a problem with your installation
