@ Tucan-Tiki:  I a little confused about your statement about oversaturation of the skin texture.  I don't know which Poser version you are using, but lately many of us have been spreading the word around the importance of Gamma Correction and the need to apply it routinely if you are using any Poser version that is not PoserPro.  Such disregard for proper monitor calibration will only lead to overblown specular highlights and oversaturation of all textures.  The bluishness on M4's skin texture is to counter-balance the redness of the texture and, IMHO, a rather cheap way at correction.  BB's method not only corrects but enhances the texture as well as applies Gc.
