I’m working on getting replays working in my project, but UE4 is not saving them. They’re being started/stopped by the “Execute Console Command” blueprint in accordance with the respective console commands that are listed in the documentation. Since the output log states that replays are not enabled for Play In Editor builds, I’ve been running the project as a standalone game, which shouldn’t have that restriction as the other ways are listed with “PIE” next to them.
I’m using version 4.15.2, if that helps.
