Steps to Reproduce

  • Use the default replication system (not Iris).
  • Have a multi-player map which uses WorldPartition (no streaming on server).
  • Run dedicated server (with `-traceFile -trace=“frame,bookmarks,net” -netTrace=1`) and connect client to server.
  • Load above map and have client player move around causing level streaming.
  • View trace in Insights and inspect packet details in Networking tabs.
  • Note that `ClientAckUpdateLevelVisibility` (server --> client) and `ServerUpdateLevelVisibility` (client --> server) use lots of bandwidth seemingly on sending `FUpdateLevelVisibilityLevelInfo::PackageName`.
