Strange shapes on G8 body in Render results (Iray)

DryreL

It looks fine while inspect the character in viewport but as you can see, it has some strange shapes in render. I set-up character so it would be torment to make again from scratch. How can I fix that problem without lose anything on character? Thanks in advance.

I've got an issue like this also only my shapes are black.

It is caused by an prop on my character. I deleted it and problem solved.
