Sky reflection?

[JudgeBao]

I have metal materials on my facade and the roof. So when I render the scene, some of the materials turned blue. SO I guess that is the metal reflecting the sky, any suggestion to get rid of the blue reflected thing?

Re: Sky reflection?

it is possible that you need reverse the face in SU. because the default SU material is blue. 
if its not the case lower the IOR/intensity of the reflection.

Thanks for the quick reply, I guess that it is because of the fresnel ior. Because i didnt change it when i apply the vismat. ;D
