had some trouble with the lips when I used the material system I used for the first version (the one with slightly tinted lips and more shine on them). The difference between face material and lip material caused a nasty edge under specific light situations. So I changed the lip's material settings and used the same I used for the face.

That "nasty edge" I think is what I was talking about earlier when discussing how SSS can be affected by separate materials, when I was explaining why I eliminated the scalp material and made the head all one mat. The way that SSS is calculated, based on material thickness and other measurements, at least in render engines such as Lightwave and Mental Ray. I also said at the time I didn't know if it would matter or not to Poser, since I don't really know how Poser does its fake SSS.

I did also mention that it could adversely affect the lips for the same reason, but figured it would be minimal. Maybe not. That was in the last paragraph I wrote up where I said I had mixed feelings about the lips being separated or not.

I can reattach them to the face UVs, if you guys want. It might be better for Poser and some of its shaders, but again I'm really not sure.
