No Suit Morphs for GM3 darken the legs

megagearx_eaad3c70d6

I have the No Suit Morphs for Genesis Male 3. Trouble is that for some odd reason, the legs get darker whenever I attempt an Iray render.

The picture is of the Iray preview, which shows the legs darkening whenever I try to render a no-suit. It's not matching the rest of the outfit.

How do I fix this? Was this a common problem with the No-Suit?
