Niagara Particles

In the current content example called “SkeletalMeshReproductionSystem_Demo_GPU” how can I change the 3d model of the body used in that example?
more over:

  • can I emit particles from a Static Mesh (and not a skeleton mesh"
  • can I attract particles already emitted to be attracted to another static mesh?
  • can I emit particles from an already emitted particle?
    I couldn’t find any answers either in the official documentation, or tutorials, or any other tutorial I could find (Unreal Sunsei Master Class), so I am at a bit of a loss.
    Thank you so much for your help on this
