I would research and get Bagginsbill's VSSProp which contains skin shaders ideal for all situations.  It will swap out all the old garbage in both characters and replace it a substantially better shader arrangement.  It was developed during the P7 version and has been slowly upgraded over the different iterations ever since.  But the old V4 shader composition has become completely wrong because it took advantage of deficiencies loaded in earlier Poser versions.  Using it, as is, now, looks out of place.
