There no demo support in UE4 for now, you would need to make one yourself, by recording events and replicate them
In UE4 is there the opportunity to do server-side demo-rec?
I want to be able to set up the server to record a 3-5 minute session and then play it back as a spectator. I want to be able to change the cameras as it plays back.
ie. In a car racing game, I want to be able to do a replay from different camera positions around the track like Gran Turismo or Forza.
I’m not interested in just screen capture. It is essential that I can replay the same events and move the camera.

So does that mean it remains a possibility or is that a definite “no, it’ll never happen”?
Yes it a possibility and very high actually considering UT community wants that for new UT
Demo Recording (Network Replay Capture) was added in 4.6. The only documentation I can find is from the release notes:
This allows you to save an “instant replay” of your gameplay! It captures your game’s network stream to a “demo” file that you can play back later or share with others. You can even use time-warping to slow down your game or fast-forward through it quickly.
Demo recording works automatically with any Unreal Engine game that is networking-enabled.
- To start recording, use the console command
- To play back a previously recorded game, use the console command
- Try using the slow-motion and fast-forward features! Use the console command
- For example, to play back at half speed use
- The ShooterGame sample has been updated with built-in support for browsing saved replays using the new “Demos” in-game menu. Check it out! (Note that you still have to use
DemoRecto save a replay, first.)
There’s mention of bHandleDedicatedServerReplays in the GameMode doc and this question may be of use.
