Vampire Blood Textures      This mod/resource adds 18 blood textures with a vampire theme for Slavetats or Racemenu to be used for screenshots. See the reference sheet for details. Applicable ingame via the MCM menu of slavetats or in racemenu.   The textures are mostly made for females even though some can be used on male characters as well and look just fine. Body textures are made for for UNP based bodies but I don't expect them to look too bad when used with CBBE. Fa
