Light Spots Created while Rendering

[happyface_906]

Hi.
I'm having issues with rendering surfaces with V-ray. After rendering, the surfaces are filled with dark spots as you can see in the top part of the rendering. Also, there are tiny light spots that are created on the shiny surface. I have tried several settings but don't seem to be able to resolve this issue. Does anyone know what the problem might be?
Thank you!
