If you're getting dirty splotches, like she's been rolling in the fireplace, you're probably using the ProPack textures, rather than the P4 ones. I made this mistake with Vicki 2, when I first got her. ProPack uses a different bumpmap format (jpg, I believe). See that you're using the correct texture sets. Stephanie's come with two icons in the MAT files, one for P4 and one for ProPack (PP). If you're not using ProPack, make sure you're using the P4 version. That should cure it. Melanie
