In City Sample project, UE 5.2, I’ve found a male human skeletal mesh and a static mesh respectively. How to convert / make the optimized static mesh. Thanks in advance.
More details:

  1. the skeletal mesh has 8 materials for detailed part while the static mesh has only 1 for the full body;
  2. the skeletal mesh has 4 LODs while the static mesh has only 3.
