How to make a particle effect wrap/conform to objects/terrain

I was watching a tutorial on particle effects today and I am wondering if there is a way for a particle effect (or image/decal) conform to the shape of a surface?

As you see here the particles spawn at the bottom of the player capsule (That is where it was defined to). I am wondering if there is away to basically make lay on the ground, like suggested by the poorly drawn red line. Any help would be appreciated

Okay so I found out about deferred decals and I will be playing around with this now. If anyone has any advice they can give me I would appreciate it still.
