Description

Multi Convex Hull created bodies that are not as accurate as in version 4.17 on skeletal meshes

Steps to Reproduce
  1. Download attached 4.18 project
  2. Open Physics asset for Skeletal Mesh
  3. Under Tools < Body Creation < change the Primitive Type to Multi Convex Hull
  4. Leave other Settings the same
  5. Generate All Bodies
  6. See restults
  7. Download attached 4.17 project
  8. Open Physics asset for Skeletal mesh
  9. Go to Reset Asset < New Asset Window < Change Collision Geometry to Multi Convex Hull
  10. Leave other settings the same
  11. Select OK
  12. See results
  13. Compare both results

Expected: The physics bodies are as accurate in 4.18 as they were in 4.17
Result: Physics bodies are less accurate in 4.18 then in 4.17
