Thank you for the fast the replies.
I had initially done a render to texture using a camera view and saving it on every tick. But this was without the toolset you have mentioned. My method would basically freeze the gameplay fps to almost 1. I will try out your recommendation and update here.
Hey thanks for this one, we currently already have a recorder and playback system similar to this in the project, but the replay section broke during a version change. Maybe I can use this to go through it and figure out what needs changing. Will update when Ive tried it out. Thank you.
