Currently using 4.8.1 and it seems the only way to emit particles off of a mesh is by using the emit off of skeletal mesh / vert in cascade. This works in some cases, but gets tricky when you want to emit off of a child skeletal mesh of a character. This is also tricky because the only way I’ve gotten a dynamically spawning particle system to work is by having a separate skeletal mesh character blueprint that is called for each particle effect and sets the appropriate parameters of that particle system, to point cascade to the correct skeletal mesh actor. If I am taking the more difficult route, I would love to see a simple example spawning particles off of a static mesh actor, and a good way to set that actor from blueprints as I want to dynamically spawn the particles.
