Hierarchical Instanced Static Mesh Component not working when too small poly count in Mesh

  1. Upload my Static Meshes, Set Lod Number = 2 in FBX Import Options(see link below)
  2. Create a Empty map
  3. Create a simple actor with HierarchicalInstancedStaticMesh Component
  4. Set Static Mesh of HierarchicalInstancedStaticMesh Component(see link below)
  5. Add 2 instances(maybe more)
  6. Move them manually in different directions
  7. Place the Actor in the game and turn on Mesh LODs in View Mode
  8. Try to Replace Static Mesh and move the Camera
  9. LODs not work on the lowpoly model(around 2000 poly and below) and work on hipoly(8000 poly +)

This Meshes almost copy each other, just 1 additional subdivision in Blender - It’s all the difference.
