Black outline

what is causing this? I am using Vray Sun/Sky and my building has this black line around it.

Check you color mapping - Affect Background.
Also are you using the VRay Physical Camera ?

I unchecked the effect background and I’ll try it agin. Yes I am using Vray’s Physical Camera? I’ll update with a response letting all know if the effect background was the issue. Thanks for the fast reply.

SubPixel? and unclapped colours can or may cause this aswell.
