I'm not a pro texture artist, but these look fairly good imo, or at least better than the original (not that it was bad, but I prefer more of a subtle layer of dirt than splatters). I curated it specifically for CBBE (+ 3BA) and HIMBO bodies so there are no seams. This is by no means perfect, but I may try to improve on it later.

I recommend using this retexture for blood and Xtudo's seamless soap texture for soap. The esp makes some changes to the opacity of the overlays. It includes the same changes to the soap overlay as Xtudo's. If you don't want the esp, you can delete it. It's not necessary, but the dirt won't look as intended.

I also recommend swefrida's beautiful body textures, primarily BnP - Male Skin and BnP - Female Skin!
