More of a input question rather than an issue. I know UE has a built in save system, and the online subsystem has functionality to make use of many online platform’s cloud save systems. Can these both be used with one another? I only ask because when I looked at WriteFile in the docs it takes an array of UInt 8s. Even if the 2 cannot be used together I have noticed that steam has cloud sync that uploads save files to the cloud without dealing with the coding side of things, but my concern is will other platforms have this as well? the platforms that im concerned about is EOS, and the Game Consoles.
i think you want to take a look at this one here Save System / Cloud Save / Encryption / Slot management | Fab
yeah they work together but you have to bridge them yourself - vanilla SaveGame writes .sav to Saved/SaveGames, cloud WriteFile wants bytes. so you SaveGameToMemory → bytes → WriteFile to cloud, and reverse on load
steam also has auto cloud sync that just uploads the folder without code, but thats config side and you need to handle conflicts/versioning yourself
advanced save system from fab Save System / Cloud Save / Encryption / Slot management | Fab Save System / Cloud Save / Encryption / Slot management | Fab does that bridge Save System / Cloud Save / Encryption / Slot management | Fab - you keep using save slots normally and it can sync via Steam Cloud or EOS cloud if you configure them, otherwise just local. also has encryption so the synced bytes are not plain .sav
