I modified the ‘SkeletonMeshReproductionSystem_Demo’ in the content example to make it look like the picture above, but now we only move the particles in a certain direction using any Velocity value.
Q1. Can I get that particle to move in the direction of SkeletalMesh’s vertex normal?
Q2. Can I control the particle animation that opens and gathers on the particle with dynamic parameters?

I would be really grateful if you could help.
