face_off's skin shader can be used on V4, accually on any object/person/etc that one can imagine (hopefully nobody models a booby ball......), just need to rework it a little
it's like you have a can of paint, but your brush is the wrong type and unusable on the project

another thread has a link to his tutorial to fix it, simple to do. or go the path i did when he first made it and understand how it works so you can rebuild the node structure yourself, which i do since it's only a part in the end shaders i use :)

as for what's in the packages, not sure, i steer clear of colored maps, too limiting to the end result IMO, greyscale maps much more control :)
