Multicast events aren't triggered in Replay Demonetdriver

[gddeil]

I’m working on a Replay System in a singleplayer game. I’m using the DemoNetDriver, in UE5.3.2.

The replays work well, but events don’t seem to be stored in the replays. I’ve set them to “multicast” (and even tried “run on server”) but the events aren’t called while replaying the .replay file.

I saw the following post and tried to apply the change, but still nothing:

Thanks for your tip ! ProcessRemoteFunction wasn’t called at all, because GetNetDriver is, I think, not correctly implemented, at least in the 4.12 branch. Previous code: UNetDriver* AActor::GetNetDriver() const { UWorld *World = GetWorld(); if (NetDriverName == NAME_GameNetDriver) { return (World ? World->GetNetDriver() : nullptr); } return GEngine->FindNamedNetDriver(World, NetDriverName); } I changed it to: UNetDriver* AActor::GetNetDriver() const { UWorld *World = GetWorld(); …

Any idea on how I can get the events to be called in replays?
