Vray render problem... help

[Fender]

Newbie here (obviuosly), im using Vray, Viz4.. then i rendered a test scene below. Using Direct light and Vray shadows checked on transparent and area shadows THEN...

 

the test scene looks fine except on the edges of the walls and windows, looks like there is a "wash-out", like untidy painting or what.. doesnt look like nice.. you can notice immediately... . HELP! What could be causing this?

 

 

Thanks for all the help

your hsph subdivs are too low. make it 50, and interpolation 20. give it a try. post an update.

Your Nm thresh and color thresh is to high... reduce it... that is causing the artifacts...

[Fender]

sorry guys for the delayed update... was outta town,.. anyways, i followed all your suggestions and thanks its working fine now, i increased the hsph and interpolations and decreased Nm and color tresh ... thanks the only drawback is its taking too long to render, about 10 minutes, cant imagine if i put all the details in here i think it gonna take an hour... is this normal? anways keep em coming, thanks for all the help
