Black objects on render.

[prae]

Hi i apologies if this is the wrong place,

Im rending a fly through using the physical sun sky and camera, and im getting some objects on my model appearing black but they all have the same material.

Im rendering with vray 1.5 rc3. with gi. The model has come in from dwg, so im wondering if there is a prob with that. Im sorry if this turns out not to be a vray problem, but if anyone knows why this might be happening please let me know.

Thanks
