True Raffaele - and for transparent obejcts this is true also. Still with FG
and BG split into separate passes there seems to be no cheap solution to
adding DOF to motionblurred material that I've heard of, except for those
situations where depth in a given pass can be ignored and a fixed out of
focus filter can be applied to the separate passes. Any suggestions?
