Way to make use of Skyrim's blood impact?

[Fredas]

I swing a sword at a dead NPC's leg, and I get two effects: 1) A blood spurt at the point of impact.  2) The point of impact on the NPC's body gains a random blood texture.  Ie not the entire body or the entire face, but a specific location on the body.

 

PlayImpactEffect does not work on bodies.  Other methods I know about essentially apply a texture across the entire body, as opposed to specifically the point of impact.

 

I want to make use of whatever process Skyrim is using when it does this.
