Fractured meshes with weird Normals/Reflections. You will see weird normals / reflections on the surface, seems each fracture piece has it's own reflection angle.

Repro rate: 3/3

Tested this in //UE5/Release-5.0-EarlyAcess @ CL#16730400 and the issue did not occur there, it is a regression.

Steps to Reproduce
  1. Create a new Third Person BP project
  2. In the Content Browser, search for SM_Cube_03
    • Ensure you have "Show Engine Content" enabled in the Content Brower's settings
  3. Place two instances of SM_Cube_03 into the scene by each-other
  4. Select one of the instances and create a new Geometry Collection utilizing the Fracture mode
  5. Apply a Uniform fracture to the Geometry Collection
  6. In Details, disable "Show Bone Colors" (Shift + B)
  7. Observe the differences between the two instances of the cube

Results: Normals on the fractured SM_Cube_03 do not match that of the unfractured mesh.
Expected: Normals on the fractured SM_Cube_03 matches the unfractured mesh.
