I'm with Rhia on this one.  Without any additional information from the OP, you're offering a shotgun approach as a solution.  I totally disagree with the alternate_diffuse and alternate_specular channel statement, those connections can be controlled with an HSV2 node or converting the white chip to a greyscale color.   Snarly's EZSkin3 uses those connectors for Superfly renders so there is no validity that Superfly does not like the alternates.
