I thought it was FixTintGamma, but that did nothing either. I thought it was my ENB, but turning that off did nothing. I also uninstalled Fair Skin, but the seam was still there. I use Fair Skin, which boasts being seamless as shown in the user-submitted pictures, so I know it isn't that and it was seamless before. The women in my game have a pretty noticeable discoloration between their neck and body. I've been trying to figure this out for a while now.
