[Answered] - Doubt in using Replays

I have added a replay functionality in my game using functions given in UGameInstance, however it will only replay player movements . I have other actors that control the environment (time of day , weather etc) based on saved info. Which additional info should I add to get those actors simulate in the replay ?

Just an update , I read more about Replay system and I guess I have to make the code multiplayer compatible . Will that be the only change ?

I will answer my own question just incase anyone bumps into the same issue. Yes replay system will keep track of only the replicable elements.
