This is the @WeebUVR sweat gloss maps converted to normals. It's a subtle effect just to give the illusion of depth on the sweat. Too much depth, and they look like welts, or people who stayed in the hot tub too long! There are skin presets for Lexi and M6 included for you to build on, or just load the textures manually. You have to load both the Weebu gloss maps into the gloss channel, and these normals into the normal channel. If you need to use these on top of other normals, or you want more fine control of the effect, use the textures with DecalMaker. There are 1x and 2x versions included.
The texture conversion was done in Gimp's Normal Map filter, with Invert Y on and depth 1.0 or 2.0.
