Vray Light creating un-rendered parts in render elements

[AC5L4T3R]

Hello,

In my current scene I am lighting a car. I have two overhead lights with affect reflection and specular turned off. when I have both lights on, there's a part of the car that doesn't render, only shows black squares. If I turn it off, it renders fine. If I have a blend material or vraycarpaint material I have this problem, if I have a standard grey material applied, I don't have this problem. The RGB pass is completely fine and I really can't see what the problem is. I've tried a different car (a squire model) and it renders fine.

I fixed the problem... the second light was a copy of the first. I deleted it, made a new one and the problem was fixed. I can't share the file because it's under NDA but maybe someone can replicate it.
