yeah it is hard to help without knowing your settings...but i think if you put a rectangular light right inside of your window to increas the amount of apparent light coming from the outside will help get rid of some of the splotchiness. Maybe increase the sub-division of your light cache if that is what you are using for secondary bounces in your rendering setup.

Thanks for the info steelers, Im using Irradiance -3/0 my subdiv is set 50. I'm using default camera. I'm sorry guys to bother you,.. I'm very thankful for your replies. I'll try your info steelers. Thanks

What V-Ray version do you use?
What is your setup? IR + LC?
