Trying to add what would be a tattoo to skin (Tween Ryan 7 Iray). No matter what color I make it, whether it's added to the map file or added as a LIE, it renders red.

Images attached showing it added to both a G3M with Iray G3M Maps/Shaders and G3M with Tween Ryan 7 Maps/Shaders. It's fine on default G3M, but it's red (in the render) with Tween Ryan 7 Maps/Shaders.

Why?
