Hi, I’m using the 3rd Person C++ Template. I have not touched the character class blueprints much. Only to add in an on key press event. All I’ve done was add in the create session, find session , and join session. There’s some replication issues that I’m not sure how to fix. If the host moves around before a client has loaded in the skeletal mesh component and character position will not match up.

In the image look at like 1 and line 4 for a visual representation of the problem. Important Note This issue will not occur if the Client 1 does not move at all until Client 2 successfully joins.

To Reproduce:

  1. Create brand new 3rd person template
  2. add the dependencies Onlinesubsystemnull (skip is using BP only project)
  3. in defaultengine.ini add [OnlineSubsystem] DefaultPlatformService=Null
  4. Open ThirdPersonCharacter(blueprint) and add the following code shown in the attached picture.
  5. Client 1 presses Q(creates server)
  6. Client 1 moves around in the world
  7. Client 2 presses E(joins session)
  8. Make client 1 move around and you’ll see the replication issue.

Solution: Delete the character placed in the level(this is default in the template). This will fix replication issue. If a dev could explain why this would be super awesome. :slight_smile:
