Generate color inside the crevice of scar using a mask.


I have a low and high poly mesh from zBrush. I bake the details in SP2024 to the low poly. I can't seem to figure out what map is being used for the details like my scars and teeth marks. For example, I am trying to add blood in the crevice of the scar maybe using a mask based on height or narmal.
I am not sure if this is possible. Perhaps someone can suggest a method.
