Steps to Reproduce

  1. Create an entity prefab component

  2. Copy the entities until your hierarchy contains 2 entities, in sequence, with the same ID.

  3. Place an entity with a mesh as a descendant of these 2 entities. The outliner should look like this:

    P_NAME
  entity_id_duplicate
    entity_id_duplicate
      mesh_entity

  4. Add the following component to P_NAME that disables descendant mesh components at game start.

    using { /Verse.org/SceneGraph }
using { /Fortnite.com/Game }

test_child_mesh_visible_component<public> := class<final_super>(component):
  OnBeginSimulation<override>():void =
    (super:)OnBeginSimulation()
    if:
      FortRoundManager := Entity.GetFortRoundManager[]
    then:
      FortRoundManager.SubscribeRoundStarted(OnRoundStarted)

  OnRoundStarted():void =
    for (DescendantMesh : Entity.FindDescendantComponents(mesh_component)):
      Print("Disable Descendant Mesh")
      DescendantMesh.Disable()

  5. Run the game

Expected Result

The descendant mesh component on mesh_entity should be disabled (not visible).

Observed Result

The descendant mesh component is visible.
