Last night I had an opportunity to load some content for Kids4, and I also managed to examine the skin texture shaders.  Sadly, those shaders are exactly the same as V4's and M4's, a blue Diffuse_Color on the PoserSurface to "correct" the redness of the skin texture.  As Laurie, mentioned, VSS will correct that.  I have prepared some renders and settings just to illustrate the differences you will notice if corrective implementation is taken to improve your scene.
