Setting up footprints as decal?

So i am trying to use a decal i have made as a footprint when the character walks, i have set up notifies but i cannot cast them to the player location and have no idea how, if anyone could help then that would really be appreciated as there are 0 tutorials.


You need to add additional elements to your character. These elements will help find you locations to generate decals. Try to follow this tutorial.

looking at it i think i can make it work for what i want, thanks a bunch
