VrayIes shadow problem

[blackyesnegro]

Hello I'm new in this forum,

I'm making a bathroom scene in vray 1.5 sp2, and I have an odd shadow produced by the Ies light.

Here you can see the same effect (like a hole) in every sinks I put in the scene, i think could be some problem with the sink model. i've changed the shadow setup from de Ies, and there are changed but not that i want.

 

here you can see some diferents samples of it.
