The fast-moving ribbon particle trail looks different on the server and client.
It looks as though the client was drawing the previous frame.

Steps to Reproduce


  1. Open attach project in Editor
  2. Set the value 2 for "Number of player" option
  3. RunPIE
  4. Press 1 Key in Server


Client can see the long trail effect more than server.


Server and Client can see the same trail effects.


Repro is to move static mesh with attached trail particle at high speed. The server synchronizes movement coordinates and synchronizes location with client with RepNotify.
