[UE4.24 - Niagara] Emit particles from a moving mesh

Hi everyone,

I’m new in Unreal Engine and I’ve been struggling with a problem for few days now.
I created a 1st person game project.
I imported an FBX mesh with a mocap animation. When I place it in my scene, everything works just fine. The character moves properly [Screen1.png].
My goal now is to get that mesh to emit particles. So I made a particles emitter and system which works fine in the preview [Screen2.png].
I remembered that I needed to link everything with a Blueprint, so I made one. I didn’t really know what kind of Blueprint I should make, so I tried with 2 differents kinds (Actor & Character) [Screen3.png & Screen4.png].
The thing is I can’t manage to make my character emit anything when I press Play or Simulate.

Do you guys have an idea of how I could achieve it ?
I’m pretty sure it’s easy, but as I’m new, I don’t really know what I’m doing wrong.

N.B. : Note that my mesh is a non-playable character. I just need it to move on its own so I can render everything up with a camera.
