Black Circle Rendered in Mirror Reflection

[stephen_ocallaghan]

Im using vray for sketchup but each time I render its as if my position, perspective is rendered as a black dot in mirror reflections. Does any one know why and how I can stop it? I have attached a couple of screen shots to show how it follows me around as I render from different positions.
Thanks

This is to mask out the photographer...
Try lowering the reflection threshold in the material or global. (I don't know the exact name for that parameter right now.)
