Spawning and Controlling Decal parameters via Blueprint

I’ve created a blood emitter with an event generator so that the blood droplets spawn splats which use an animated image sequence to spread out upon impact. Unfortunately, the splats do not angle themselves to line up with terrain or other surfaces the way a Decal does…so I need to replace them with a Decal. What I need though is:

  1. The Decal to spawn on the ground at a specific time/event set within Cascade (blood drops hitting ground)
  2. To begin playing through the 0-1 dynamic parameter I’ve setup in the decal material for its flipbook
  3. To stop playing at the value of 1.0 in the dynamic parameter and remain there as a persistent splat.
  4. To spawn ANOTHER Decal which applies itself to the character and does all of these same things, only follows character around.

Here is blood as it currently stands. No decals at all, no blood damage remaining on character, just animated splat particles on the ground.
