hierarchical Instanced static mesh component - How to correctly in BP?

Hey guys, i am working on some blueprints atm and have like a small problem now.

Can someone tell me Difference in Unreal between:

  • Adding multiple HISMC in ONE Blueprint (lets say 10 stones)
  • Adding 10 Blueprints with ONE HISMC in it (one stone in One Blueprint, but 10 Blueprints, makes 10 Stones in the end)

Does this actually make a difference? Visually basically not, but in rendering time or how the engine does handle it?

I am used to add HISM all in one blueprint and it can handle thousands of meshes with no problem at all i cant say how is the performance if you use more blueprints to handle that but from my perspective its very performant
