The images below show the suit (to be used for Obama and Trump) as it is in the window and rendered with basic opengl and as it looks rendered with iray (with the light reflections off the suit).

What could be making that happen? I've tried changing values like reflection, velvet, etc. Nothing makes the light reflection go away.

Any ideas?
