Weird circles

[brunocarvalho]

Sometimes i am getting these weird shapes on my objects when i render. This huge circle like a big fingerprint and i don't know were this come from.

 

Example:

 

I deleted my lights, placed a simple material deleted the rest of the arrays i made and rendered and it is still there.

 

I asked on other places on the internet but no one knows what this is. I'm learning all by myself so i don't know anyone to ask what i am doing wrong. If someone could give me a hand i would be extreamly gratefull.

 

This is the cleaned version of the Max file however it still shows the pattern on the balconys.
