  1. You will need to load a previously captured replay. To do so, click “Load capture and select from the list presented.

  2. Once a capture is selected, you must now create at least one video set, and apply your settings to be replayed. See Replay settings below for information on the various settings.

  3. If you are using the Luna Playground attribute to surface your game variables, you can find these in the Field Sets section of a Video Set.


  1. When you have created your video set(s), you can press Replay!”. The editor will enter play mode and start to replay and capture videos. Do not interfere with Unity whilst recording is taking place.

  2. Once finished, you may access Project > LunaTemp to find the output video(s).
