I’m just modifying the existing Niagara System located in Content Example
ContentExamples/Content/ExampleContent/Niagara/NeighborGrid3D/StructuralSupport/StructuralSupport
and plugged in the code provided by @Michael.Galetzka, set a bool for the to-be-killed particles. And then adding a Kill Particles action.
I’m still trying to achieve the same thing as the demo to make a particle-filled actor that moves with skeletal meshes. It’s not a straight forward process as skeletal meshes don’t produce mesh distance field, so one would have to first make a cut-up static mesh, then fill the limbs individually so each emitter can be assigned to follow a bone later on.
