Got rid of seams in Wet Function's women textures as best as I could. Neck and hands specular seams are WAY less noticeable.    Incompatible with Skyrim LE due to BC7 compression, but I suppose you can downgrade them to whatever format it uses.   Update @alex77r4 converted them to LE and graciously shared them with us.   They should totally work, but please tell us in the comments if they mysteriously don't.
