Why is this happening to me?

What should cause this result? no shadow in the billboards, splotches in a no reflective gray diffuse material, and some weird metal results?
it has a sun and a physical camera + medium quality vray express settings.

Also check if you have Reflective caustic enable on Indirect Illumination rollout. Some time produce that kind of issue.
