City Sample Vehicles meshes not appearing properly when packaged

hello everyone, I am looking at using the City Sample Vehicles pack in my project. For some reason I’m getting this weird behavior where the vehicle skeletal meshes don’t render properly when packaged .
In the editor it looks fine . The physics/collisions match the correct static meshes. so far I’ve tried to:

  • make sure the entire city sample vehicle folder is correctly migrated/copied from a different project
  • forcing the entire folder to cook
  • doing a clean rebuild/package
  • validated all the assets
  • made sure there’s no errors or warnings when packaging.
    Does anyone have any idea what could be the issue or at least in what direction I could research?
