How does Fortnite handle Player Visibility with the Replication Graph?

Hello,

We’re using the Replication Graph and are considering options on how to remove the enemy team characters from the rep view while they are out of sight. We’ve considered line tracing to the characters future point based on velocity but this sounds expensive for a game with a lot of players like Fortnite. Could you share any insights on how you’ve solved the problem please?

Hi,

I don’t believe Fortnite uses any sort of line tracing. In the replication graph, this kind of thing is generally handled by the dynamic spatial frequency node, which can adjust the replication frequency of actors depending on their position relative to the client’s pawn’s field of view.

Thanks,

Alex

Hi Alex. That’s interesting to hear, thanks for the info.

I’m assuming you have a system in place to prevent ESP style hacking… is there something else you would use to handle this? Or is Easy Anti-Cheat generally enough to keep them at bay for Fortnite?
